Global Leading Market Research Publisher Global Info Research announces the release of its latest report “Infrared Gas Sensor for Chamber Cleaning End Point Monitoring – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032″. As semiconductor manufacturers face escalating pressure to reduce wafer fabrication costs (reactive gases expensive, cleaning time reduces throughput) and extend chamber life (over-cleaning damages chamber walls, under-cleaning generates particles), traditional time-based chamber cleaning processes are inherently inefficient due to variable cleaning rates (temperature, pressure, gas flow, film thickness). Infrared gas sensors for chamber cleaning end point monitoring address these challenges by directly measuring reaction byproducts (SiF₄, CF₄) released during plasma/thermal cleaning, enabling dynamic end point detection. Infrared Gas Sensor for Chamber Cleaning End Point Monitoring is a gas-sensing device used to precisely detect the end point of a plasma or thermal cleaning process inside semiconductor processing chambers. These detectors monitor specific infrared-absorbing gases, such as SiF₄, CF₄, that are released during chamber cleaning, and determine when the residue (such as polymer buildup from previous etching or deposition steps) has been fully removed. Upstream raw materials for infrared gas sensors for chamber cleaning end-point monitoring primarily include infrared light sources, filters, and photodetectors. Typical suppliers include Hamamatsu, Asahi Kasei Microdevices, OSHINO LAMPS, International Light Technologies (Labsphere), Newport, Andover Corporation, Edmund Optics Inc., and Thorlabs, Inc. Downstream applications include chamber cleaning endpoint detection in CVD equipment. Typical customers include YMTC, Applied Materials, Lam Research, Tokyo Electron Ltd., ASM International, Naura, and Piotech. As a core sensing device in high-end manufacturing fields such as semiconductors and photovoltaics, infrared gas sensors for chamber cleaning end-point monitoring enjoy significant gross profit margin advantages due to their high technological barriers. Overall gross profit margins generally remain in the 45%-55% range.

1. The Chamber Cleaning Challenge: Time-Based vs. Endpoint Detection
Chemical vapor deposition (CVD) is a chemical process in which a volatile precursor reacts with the wafer to deposit a conformal film of material on the wafer. These films include polysilicon, silicon dioxide, silicon nitride, and other silicon-based materials. CVD not only deposits highly uniform films on the wafer, but also on chamber surfaces. From deposition on chamber walls, the chamber must be cleaned regularly to remove the buildup. Removal of chamber deposits is achieved by introducing reactive gases, such as fluorine radicals. These radicals react with the surface film to generate gases such as silicon tetrafluoride and carbon tetrafluoride, which are then removed from the chamber. The optimal chamber cleaning time is a complex function of a number of variables, including the thickness of the deposited material, temperature, pressure, reactive gas delivery, and material chemistry. Traditional chamber cleaning is a time-based process. Due to the complexity of the chamber environment, cleaning rate variables may change or drift. A single cleaning time for a given chamber can vary significantly over time. Therefore, a uniform cleaning time cannot meet all chamber cleaning requirements. Most time-based processes are designed to over-clean to ensure complete removal of CVD films from multiple chambers. Over-cleaning reduces wafer throughput, causes excessive use of reactive gases, and can damage chamber walls. Conversely, under-cleaning causes the deposited film to accumulate over time, generating particles, which ultimately reduces product yield. The Infrared Gas Sensor for Chamber Cleaning End Point Monitoring determines optimal chamber cleanliness by directly measuring the amount of silicon tetrafluoride or carbon tetrafluoride generated. This dynamic approach eliminates the uncertainty of time-based methods. Furthermore, the infrared gas sensor can save costs, reduce cleaning time and reactive gas usage, and extend chamber life.
2. Market Dynamics & Semiconductor Industry Context
According to the World Integrated Circuit Association (WICA), the global semiconductor market size is expected to reach US$ 600.2 billion in 2024, a year-on-year growth of 17%.

According to our data, global shipments of infrared gas sensors for chamber cleaning end point monitoring will reach approximately 1,700 units in 2024, and global shipments are projected to grow at a compound annual growth rate exceeding 12% over the next five years. Key players in the NDIR EPDs for Chamber Clean market include MKS Inc., HORIBA, Teledyne API, and Cubic Instruments. High-end products in the industry are dominated by manufacturers in the United States and Japan. To reduce reliance on imported technology and products, Chinese manufacturers are actively pursuing independent research and development and technological breakthroughs. Chinese NDIR EPDs for Chamber Clean are gradually meeting domestic demand, and the process of domestic substitution is accelerating.
3. Technology Deep-Dive: Single vs. Multi-Gas Detection
Single Gas Detection Type (65% of 2025 revenue): Monitors one byproduct gas (typically SiF₄ or CF₄). Lower cost, simpler calibration, sufficient for most CVD/PECVD cleaning applications. MKS Inc.’s 2026 “SiF₄-Sense” single-channel NDIR sensor detects 0-1,000 ppm SiF₄, 1-second response, 2% accuracy. Largest segment.
Multi-gas Detection Type (35% of revenue): Monitors SiF₄ and CF₄ simultaneously (or other gas pairs). Higher cost, provides cross-validation, identifies cleaning anomalies (e.g., CF₄ indicating incomplete reaction). HORIBA’s 2026 “Multi-EPD” dual-channel sensor (SiF₄ + CF₄) achieves 1ppm detection limit, 0.5-second response. Fastest-growing at 12% CAGR (advanced nodes require process verification).
Core components: Infrared source (MEMS thermal emitter or Globar), optical filter (bandpass 8-12 μm for SiF₄), photodetector (pyroelectric or thermopile), sample cell (long-path length for sensitivity), and reference channel (for drift compensation).
Technical breakthrough (2026): Teledyne API’s “Quantum Cascade Laser (QCL)-EPD” replaces traditional NDIR with QCL source (tunable 5-12 μm), achieving ppb-level sensitivity (1,000x better than NDIR), 0.1-second response, and immunity to cross-interference. Currently for leading-edge nodes (3nm, 2nm), high cost (US$ 50,000+ per sensor).
Ongoing challenges: Condensation (SiF₄ reacts with moisture, forms silica particles blocking sample cell). Cubic Instruments’ 2026 “HeatedCell” maintains sample cell at 150°C, preventing condensation, reducing maintenance from weekly to quarterly. Calibration drift (IR source aging, detector response changes). MKS’s 2026 “AutoCal” system injects reference gas weekly, adjusts gain automatically, maintaining 2% accuracy for 6 months.
