Global NDIR End Point Detector for Chamber Clean Market Strategic Research Report

Scope of the Report

The global NDIR End Point Detector for Chamber Clean market size is predicted to grow from US$ 25.34 million in 2025 to US$ 45.24 million in 2032; it is expected to grow at a CAGR of 8.7% from 2026 to 2032.

An NDIR (Non-Dispersive Infrared) End Point Detector for chamber clean applications 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, etc. 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.

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. Over time, deposits accumulate on chamber surfaces, leading to particulate matter and potential contamination, which reduces wafer yield. To reduce particulate matter 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 NDIR End Point Detector for Chamber Clean 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 NDIR End Point Detector for Chamber Clean can save costs, reduce cleaning time and reactive gas usage, and extend chamber life.

According to the World Integrated Circuit Association (WICA), the global semiconductor market size is expected to reach US$620.2 billion in 2024, a year-on-year growth of 17%. The market for NDIR End Point Detectors for Chamber Clean (NDIR EPDs) is rapidly growing, driven by advances in semiconductor manufacturing technology and increased spending on wafer fab equipment. According to our data, global shipments of NDIR chamber cleaning endpoint detectors 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 Sifang Optoelectronics. High-end products in the industry are dominated by manufacturers in the United States and Japan. To reduce reliance on imported technology and products, domestic manufacturers are actively pursuing independent research and development and technological breakthroughs. Domestic NDIR EPDs for Chamber Clean are gradually meeting domestic demand, and the process of domestic substitution is accelerating.

From a regional perspective, North America (the United States) and the Asia-Pacific region (particularly Japan, South Korea, and China), as the two most important global CVD equipment production regions, have strong demand for NDIR EPDs for Chamber Clean. North America will account for over 45% of the market share in 2024. China will see the fastest growth, with our data projecting sales in China to increase by over 20% year-over-year in 2024.

With the overall improvement in the semiconductor industry's economic climate, the global semiconductor equipment market is experiencing rapid growth. Furthermore, as semiconductor production lines continue to upgrade, wafer fabs' demand for the quantity and performance of thin-film deposition equipment will continue to increase, driving the expansion of the NDIR End Point Detector for Chamber Clean market.
