Global Semiconductor Process Gas Abatement Systems Market Outlook, 2031

Market Insights Abatement has transitioned from a sub-fab afterthought into a regulated capital requirement at the center of fab permitting and net-zero commitments, because the U.S. EPA, the EU Industrial Emissions Directive revisions, and national frameworks in South Korea and Japan are progressively lowering allowable perfluorocompound thresholds, converting voluntary NF3 and SF6 reduction programmes into mandatory retrofit obligations at operating fabs. The greenfield construction cycle is the most consequential structural demand driver, with the CHIPS Act, EU Chips Act, and parallel incentive programmes in Japan and India sustaining abatement capital demand into the late 2020s, and each new 300mm fab requiring between 15 million and 40 million dollars in abatement equipment over a two-to-three-year build timeline. The performance bar is being reset by industry benchmarks rather than by procurement preference, with the SEMI SCC Whitepaper "Overview of F-GHG and Nitrous Oxide Semiconductor Abatement Technologies" establishing a minimum Destruction and Removal Efficiency for CF₄ of greater than 95 percent and a maximum goal of greater than 99 percent, figures that represent a significant step beyond the legacy default values used in many ESG reports. Technological leadership has moved ahead of the benchmark, with DAS Environmental Expert's TILIA system independently validated to achieve over 99.9 percent DRE for CF₄ and other fluorinated greenhouse gases, demonstrating that destruction efficiencies exceeding the SEMI SCC upper range are both technically feasible and economically advantageous as carbon taxes rise. Process-level intensity is compounding independently of capacity expansion, because each successive technology node from 128-layer 3D NAND moving toward 300-layer-plus and logic shrinking from 5nm to 2nm and below adds etch steps and per-wafer PFC emissions, sustaining aftermarket and retrofit demand between greenfield cycles. Fab operators are embedding abatement performance into their own net-zero commitments and supplier qualification criteria, with TSMC, Samsung, SK Hynix, and Intel treating PFC destruction as a Tier 1 supplier prerequisite, and TSMC's N2O reduction project lifting electric-heating local scrubber reduction rates from 42 percent to 90 percent across Fab 12A, 12B, 14A, 14B, 15A, and 15B as of October 2025.

DAS Environmental Expert has established the performance benchmark with its TILIA platform exceeding 99.9 percent DRE for CF₄, and the company's SALIX system became the world's first commercially available point-of-use abatement solution for wet bench semiconductor processes, proven fully effective after six months at a Taiwan-based global foundry with zero harmful substances in the exhaust, SEMI S2 and German TA-Luft compliance, and one unit per wet bench replacing elaborate space-filling change-over modules. Ebara competes across combustion and plasma modalities, launching the Model LA+ combustion-based exhaust gas abatement system at SEMICON Europe 2025 with over 95 percent DRE and enhanced processing and durability over its predecessor Model TND, while its Model LPCMN entered sales in January 2025 with four inlet connections and a six-inlet variant following within the year. CS Clean Solutions occupies the dry abatement niche with proprietary dry-bed chemisorption technology that converts hazardous gases into stable inorganic salts without fossil fuels or water, and the company has extended into plasma abatement for fluorinated greenhouse gases and for GaN deposition abatement of H2 and NH3, giving it coverage across etch, ion implantation, chamber cleaning, HDP CVD, LPCVD, PECVD, MOCVD, and ALD applications. Air Liquide's Universal Plasma Abatement System uses atmospheric microwave plasma reaching 6,000 degrees Celsius to achieve over 99 percent DRE for most PFCs and over 95 percent for difficult gases including SF6 and CF4, operating fuel-free with more than 99.5 percent uptime, annual maintenance, and the capacity to manage exhaust from up to four tools simultaneously. Korean suppliers are scaling on domestic fab demand, with Global Standard Technology offering POU scrubbers, PFC and VOC abatement, burn-wet scrubbers, dry scrubbers, and chillers, and UNISEM having developed Korea's first gas scrubber before expanding into gas abatement systems, chillers, and eco-friendly equipment for leading semiconductor manufacturers worldwide.

Market Dynamics Driver: Mandatory PFC destruction thresholds converting voluntary sustainability targets into capital obligations
• Regulatory tightening is no longer aspirational, because the U.S. EPA, EU Industrial Emissions Directive revisions, and national frameworks in South Korea and Japan are progressively lowering allowable PFC thresholds and converting voluntary NF3 and SF6 reduction programmes into mandatory retrofit obligations at operating fabs, creating a compliance-driven replacement cycle that operates independently of capacity expansion.
• The economic logic is reinforced by carbon pricing, because CF₄ carries a Global Warming Potential of 7,390 and even a few tons of unmitigated emissions correspond to millions of tons of CO₂ equivalents, making high-efficiency abatement a direct financial hedge against rising carbon taxes rather than a discretionary environmental expenditure.
• Fab operator commitments are creating demand beyond the regulatory floor, with TSMC planning to complete retrofitting or replacement of all existing on-site electric heating treatment equipment across all fabs by 2028, and the company's methane-assisted electric-heating scrubber retrofit achieving 90 percent N2O reduction alongside a 40 percent further reduction in NOx discharge.

Challenge: Byproduct formation and NOx trade-offs complicating technology selection
• Plasma-based abatement achieves the highest destruction efficiencies but generates NOx byproducts that warrant further attention, and methane-assisted plasma-wet local scrubbers introduce CH₄ to enhance N₂O decomposition while minimizing NOx formation, a balancing act that adds process complexity and requires downstream control beyond the primary abatement step.
• Wet scrubbing handles water-soluble gases effectively, with pre-oxidation combined with wet scrubbing removing over 80 percent of NO₂ in laboratory tests for room-temperature exhaust, but the technology alone cannot destroy stable perfluorinated compounds, forcing hybrid burn-wet-scrub configurations that combine high-temperature PFC destruction with downstream particulate capture at higher capital and operating cost.
• The capital intensity falls hardest on operating fabs pursuing retrofit rather than greenfield construction, because existing sub-fab footprints constrain equipment selection and the addition of point-of-use units alongside centralized scrubbing infrastructure creates integration complexity that greenfield designs avoid by specifying abatement capacity from the outset.

Trend: Predictive maintenance and AI-driven sub-fab intelligence displacing reactive service models
• Sub-fab intelligence has moved from condition monitoring to predictive intervention, with Edwards' models achieving up to 95 percent prediction accuracy across pump and abatement systems, enabling fabs to plan the unplanned, streamline maintenance schedules, reduce costs, and prevent single-point failures from cascading into fab-wide downtime and yield loss.
• The service model is shifting from generic maintenance packages toward outcome-based engagement, with Edwards' Semiconductor Intelligent Service team working backwards from customer goals in yield, uptime, or sustainability rather than selling standard service tiers, and extending data collection beyond its own tools to a range of sub-fab equipment to provide machine health and availability insights across the ecosystem.
• Direct water recycling from waste gas abatement is emerging as a parallel sustainability frontier, with DAS Environmental Expert developing solutions for recycling wastewater from waste gas abatement processes, targeting pollutants specific to each abatement process, minimizing equipment footprint, and optimizing recycling rates to reduce the environmental impact of semiconductor manufacturing beyond air emissions alone.



Segment Analysis By System Type
• POU abatement has gained market leadership because it delivers higher emission control efficiency and direct treatment of process gases at the tool level, and a leading-edge logic fab running sub-5nm nodes may deploy 200 to 400 individual POU units alongside centralized scrubbing infrastructure, with DAS's SALIX proving that one system per wet bench can eliminate elaborate extraction systems and achieve zero harmful substances in the exhaust.
• Centralized scrubbing infrastructure remains essential for treating the aggregate exhaust stream from multiple process areas, and the technology is being re-engineered around N2O reduction and NOx control, with TSMC's methane-assisted electric-heating local scrubber retrofit achieving a 90 percent N2O reduction rate and a 40 percent further NOx reduction while being included in the standard design for new fabs.
• Hybrid configurations combining burn-wet-scrub architectures are the fastest-growing system type because fab operators require simultaneous high-temperature PFC destruction and downstream particulate capture, a dual requirement that point-of-use thermal or wet-only systems cannot satisfy alone, and the hybrid approach is reshaping which equipment vendors capture margin as advanced-node fabs shift toward point-of-use treatment for rising process gas volumes.

By Abatement Technology
• Thermal oxidation systems hold the largest service-type share because of their efficacy against PFCs and hydrofluorocarbons generated during CVD and plasma etch processes, and Ebara's Model LA+ combustion platform achieves over 95 percent DRE while addressing reactive byproduct formation that hinders continuous operation, with a six-inlet variant extending capacity within a single unit.
• Plasma is the most effective option for mitigating fluorinated greenhouse gases and N2O emissions, and Air Liquide's UPAS system uses atmospheric microwave plasma at 6,000 degrees Celsius to achieve over 99 percent DRE for most PFCs and over 95 percent for SF6 and CF4, operating fuel-free with over 99.5 percent uptime and managing exhaust from up to four tools, while methane-assisted plasma-wet scrubbers address N2O removal with minimized NOx formation.
• Catalytic decomposition is advancing through government-backed research, with the Korea Institute of Energy Research developing a high-durability catalyst that maintains full performance in breaking down carbon tetrafluoride after 4,000 hours of continuous operation, stably decomposing over 98 percent of high-concentration CF₄ at 700 degrees Celsius, a lower operating temperature than conventional catalysts, and the technology is applicable across semiconductors, displays, and waste refrigerants.
• Wet scrubbing is the practical solution for water-soluble and acidic gas streams, with pre-oxidation combined with wet scrubbing removing over 80 percent of NO₂ from room-temperature exhaust in laboratory tests, and the technology is frequently integrated into burn-wet-scrub hybrids where the wet stage captures particulate and acidic byproducts generated by upstream thermal or plasma destruction.
• Dry chemisorption-based abatement converts hazardous gases into stable inorganic salts without fossil fuels or water, and CS Clean Solutions has built its franchise on this passive technology with a track record for safety, process reliability, and environmentally sustainable manufacturing, extending the approach into plasma systems for fluorinated greenhouse gases and GaN deposition abatement of H2 and NH3.
• Hybrid platforms that combine multiple destruction mechanisms are becoming the default specification for advanced-node fabs, because no single technology simultaneously achieves greater than 99 percent DRE for stable PFCs, controls NOx byproducts, and captures particulate matter, and the burn-wet-scrub hybrid configuration is positioned to capture the fastest-growing share of new abatement capital.

By Semiconductor Process
• Etch processes are the primary source of high-global-warming-potential PFC emissions including CF₄, SF6, and NF3, and plasma abatement is the most effective mitigation option for these gas streams, with Air Liquide's UPAS explicitly designed to destroy high-GWP PFCs and HFCs emitted by etching processes and CS Clean Solutions offering plasma abatement for the same application.
• Deposition processes generate PFC and hydrofluorocarbon emissions that thermal oxidation systems are most effective against, and CS Clean Solutions covers HDP CVD, LPCVD, PECVD, MOCVD, and ALD applications with dry and plasma abatement platforms, while the sector's diversity of gas chemistries requires abatement systems configured for process-specific exhaust profiles.
• Chamber cleaning with NF3 and fluorinated gases is a major contributor to PFC emissions, and the conversion of what were voluntary NF3 reduction programmes into mandatory obligations is directly increasing abatement requirements for chamber cleaning exhaust streams at operating fabs across the United States, Europe, South Korea, and Japan.
• Diffusion and oxidation processes generate nitrous oxide emissions that require dedicated abatement, and TSMC's N2O reduction project specifically targets electric-heating local scrubbers serving these processes, achieving a 90 percent reduction rate through methane-assisted reduction-oxidation reactions and extending the retrofit across six fabs with full deployment planned by 2028.
• Ion implantation produces hazardous hydride and fluoride gas streams that require abatement before release, and CS Clean Solutions explicitly covers ion implantation exhaust gas treatment within its dry-bed and plasma abatement portfolio, addressing dopant gases including arsine and phosphine alongside fluorinated species.
• Photolithography, wet bench cleaning, and compound semiconductor manufacturing introduce abatement requirements that differ from mainstream CMOS flows, and DAS's SALIX for wet bench applications and CS Clean Solutions' GaN deposition abatement for H2 and NH3 illustrate how process-specific exhaust chemistries demand purpose-built abatement configurations rather than generic scrubber designs.

By Semiconductor Device Type
• Leading-edge logic is the most demanding abatement application because sub-5nm nodes add etch steps and per-wafer PFC emissions, and a single advanced logic fab may deploy 200 to 400 point-of-use abatement units alongside centralized scrubbing, giving abatement equipment density a strong correlation with primary deposition and etch tool spending.
• Memory manufacturing drives high-volume abatement demand because 3D NAND layer counts moving toward 300-layer-plus and DRAM scaling multiply etch and deposition steps, and the concentration of memory fabs at Samsung and SK Hynix in South Korea makes the region a critical regulatory and procurement geography for abatement systems.
• Silicon carbide and gallium nitride power device manufacturing introduces abatement requirements for hydrogen, ammonia, and metal-organic precursors that differ from silicon CMOS exhaust profiles, and CS Clean Solutions' plasma abatement for GaN deposition of H2 and NH3 represents a purpose-built response to wide-bandgap process chemistries.
• Compound semiconductor processes using gallium, arsenic, and indium precursors require abatement that captures toxic metal-organic species alongside fluorinated gases, and the segment's exhaust chemistry diversity makes it a qualification-intensive application where dry chemisorption and plasma platforms compete on species-specific removal performance rather than generic DRE metrics.
• Analog and mixed-signal manufacturing generates lower per-wafer PFC volumes than leading-edge logic but operates across mature nodes with older abatement infrastructure, and the segment represents a retrofit demand pool as voluntary reduction programmes convert into mandatory obligations at fabs that previously deferred abatement upgrades.
• MEMS and sensor fabrication uses specialty gases including xenon difluoride and hydrofluoric acid vapor that require abatement configurations distinct from standard PFC destruction, and the segment's smaller exhaust volumes favour point-of-use systems over centralized infrastructure, creating demand for compact platforms with species-specific scrubbing media.
• Photonics, quantum devices, and research-scale fabrication introduce abatement requirements that do not map onto high-volume CMOS flows, and these applications favour configurable and modular platforms that can be adapted to novel gas chemistries without the capital commitment of a full-scale production abatement line.

Regional Analysis
• North America's abatement demand is being rebuilt through CHIPS Act industrial policy, with Edwards Vacuum completing construction of a 319 million dollar semiconductor supply chain facility in Genesee County, New York, a decision that followed passage of the federal CHIPS and Science Act and was supported by New York's Green CHIPS legislation, and the facility is positioned to supply vacuum and abatement equipment to the domestic fab capacity being constructed under federal incentives.
• Europe's abatement landscape is defined by the EU Chips Act and the EU Industrial Emissions Directive revisions, which are progressively lowering allowable PFC thresholds alongside national frameworks in South Korea and Japan, and the region hosts DAS Environmental Expert in Dresden, whose TILIA platform exceeds SEMI SCC benchmarks and whose SALIX wet bench system is SEMI S2 and German TA-Luft compliant, making Europe both a regulatory originator and a technology supplier to the global market.
• Asia-Pacific commands the majority of global abatement demand because TSMC, Samsung, and SK Hynix fab expansions across Taiwan and South Korea anchor the region's installed base, and environmental thresholds in China, Korea, and Japan require destruction efficiency above 97 percent for fluorinated gases, with Japan's Rapidus initiative and India's greenfield fab incentives extending the growth frontier beyond the incumbent Taiwan and South Korea base.
• South America remains an early-stage abatement market with demand concentrated in Brazil's back-end assembly and test operations rather than leading-edge front-end fabs, and regional procurement is oriented toward point-of-use scrubbers for wet bench and specialty gas applications rather than the centralized burn-wet-scrub infrastructure deployed at advanced-node logic and memory facilities.
• Middle East & Africa's abatement trajectory is policy-led and concentrated in sovereign semiconductor programmes, with Israel's manufacturing ecosystem and Gulf greenfield fab investments under Vision 2030 creating first-time demand for abatement systems as new capacity is designed with environmental compliance embedded from the outset rather than retrofitted after permitting.
