Wafer Used Oxidation Equipment Market Overview
The global Wafer Used Oxidation Equipment market was valued at US$ million in 2024 and is anticipated to reach US$ million by 2031, witnessing a CAGR of %during the forecast period 2025-2031.
The wafer used oxidation equipment market—centered on pre-owned vertical and horizontal furnaces for dry/wet thermal oxidation—continues to expand as chipmakers scale specialty capacity and control capex. Demand spans analog, power discretes (Si/SiC), sensors/MEMS, display drivers, and mature logic where 150–200 mm lines dominate. Purchasing certified refurbished oxidation tools offers 40–70% cost savings versus new systems, faster installation lead times, and proven process stability—key advantages while greenfield megafabs absorb OEM production slots and long-lead subassemblies.

Market Drivers
Growth is propelled by three converging forces. First, the upcycle in automotive and industrial electronics elevates oxide quality and uniformity requirements on legacy nodes, increasing tool counts at 200 mm. Second, the wide-bandgap transition boosts oxidation demand for gate oxides and sacrificial oxides on SiC flows, where high-temperature, low-defect growth is essential. Third, cost and ESG pressures push fabs to extend asset life through refurbishment, chamber re-tubing, and controls modernization rather than buying new. For IDMs and foundries running high-mix products, used furnaces provide a low-risk path to add dedicated recipes without disrupting existing fleets.
Technology Landscape
Most transactions involve batch vertical furnaces with quartz tubes and advanced temperature profiling for 150/200 mm, plus select 300 mm tools released from logic/memory nodes. Process sets typically cover dry O₂ growth for thin oxides, H₂O (steam) oxidation for thicker layers, and nitride/oxynitride options via add-on kits. High-value upgrades include modern PID controllers, recipe editors with SECS/GEM connectivity, FOUP/SMIF front-ends, multi-zone heaters for tighter within-wafer uniformity, and advanced boat loaders that reduce particle adders. Refurbishers replace worn components (tubes, boats, O-rings), recalibrate thermocouples/pyrometers, and validate film thickness, refractive index, and defectivity to near-OEM specs.
Notable Trends
Certified-refurb channels are displacing gray-market brokers. Buyers now expect documented as-run data, vacuum integrity tests, safety interlocks, and spare-parts packages. Digital retrofits—data loggers, remote diagnostics, and predictive maintenance analytics—improve uptime on legacy platforms. Chemical usage and abatement are getting attention: closed-loop DI water management for steam generators, improved exhaust handling, and energy-efficient heater drives align with corporate sustainability goals. On the process side, tighter edge exclusion and micro-roughness control are differentiators for advanced sensor and SiC lines.
Segmentation
By wafer size, 200 mm leads revenue, followed by 150 mm; 300 mm units appear intermittently as top-tier fabs retire older lots. By oxidation type, wet oxidation tools (high growth rate) dominate for thick field oxides, while dry oxidation equipment is preferred for thin gate oxides and precision films. By end use, automotive/industrial power (Si, SiC), analog/mixed-signal, MEMS, and discrete devices account for most placements, with R&D and universities rounding out demand. By sales channel, OEM-certified refurb programs and specialized third-party refurbishers outpace simple secondary resales due to warranty, documentation, and process support.
Regional Dynamics
Asia-Pacific is the largest market, supported by extensive 200 mm ecosystems in China, Taiwan, South Korea, Japan, and Southeast Asia. North America shows healthy demand from onshoring initiatives, SiC capacity adds, and specialty analog lines. Europe remains resilient on the strength of automotive, industrial, and power semiconductors, with purchases often tied to modernization grants and energy-efficiency targets.
Competitive Landscape
The ecosystem includes original tool makers with certified-used programs, dedicated refurb houses with global parts depots, and select brokers specializing in turnkey installs. Differentiation hinges on guaranteed film specs (thickness uniformity, refractive index), ramp-to-recipe time, spare parts availability (quartzware, heaters, seals), factory integration (SECS/GEM, MES hooks), and total cost of ownership. Strong applications engineering—recipe transfer, tool matching, and on-site qualification—often outweighs headline pricing.
Challenges and Outlook
Key risks involve parts obsolescence, documentation gaps, and variability across prior owners. Buyers mitigate these with comprehensive FAT/SAT protocols, acceptance criteria tied to metrology targets, and service-level agreements. Looking ahead, steady expansion in power electronics, continued 200 mm reinvestment, and sustainability-driven asset reuse should sustain growth. Vendors that combine rigorous refurbishment standards, digital upgrades, and process guarantees will capture share as the wafer used oxidation equipment market moves toward cleaner, smarter, and more sustainable operations.
