What CI Systems does
CI Systems LTD is an Israeli public company (traded on the Tel Aviv Stock Exchange under tlv:CISY) that has operated in process monitoring since 1977 and entered the semiconductor process equipment market in 1992. Its CI Semi division, established in 2001 and operating as a standalone unit since relocating to a dedicated facility in Migdal HaEmek, Israel in May 2023, develops and manufactures in-situ and in-line process monitoring and control systems for the semiconductor, photovoltaic, flat panel display, and LED industries. The product portfolio comprises two main families: the NTM line of non-contact pyrometers (NTM Delta, NTM-LW, NTM Eta, plus the SR72 calibration source and optical interfaces) for real-time wafer temperature measurement with emissivity compensation, and the WetSpec line (WetSpec200, WetSpec201, WetRad2, WetCon100, plus the patent-pending FlowCell+) for in-line wet chemical concentration monitoring using NIR spectroscopy, dual-wavelength radiometry, conductivity, and NDIR technologies. The company employs proprietary chemometric algorithms for multi-component chemical analysis and claims over 1,000 chambers and thousands of sensors installed globally, with products operating continuously in fabs for more than 20 years.
Revenue is generated primarily through direct hardware sales of monitoring instruments and sensors to semiconductor OEMs and end-user fabs, supplemented by technical support, installation, configuration services (with a US technical and service center in Fremont, California), and custom integration development. Pricing is quote-based with no public list pricing and is structured around multi-year contracts with one-year warranty coverage. The go-to-market combines direct enterprise sales with a worldwide network of local sales representatives across the USA, Taiwan, China, Europe (Germany), Singapore, and South Korea, supplemented by active participation in major SEMICON regional trade shows. Key end markets are semiconductor wafer fabrication (the primary segment, covering wet cleaning, wet stripping, wet etch, thermal/RTP, and deposition processes), photovoltaic cell manufacturing, and flat panel display production. Disclosed end users include Texas Instruments and Cabot Microelectronics, with OEM customers being integrated into tools from leading global semiconductor equipment manufacturers.

CI Semi competes with KLA in process monitoring, though KLA addresses a much broader set of applications and customers.
- Entegris: Entegris supplies materials and process solutions for semiconductor and adjacent industries, including liquid chemistry delivery and filtration. While broader in scope, its wet process and contamination control products overlap with CI Semi's wet chemistry monitoring customer base.
- Thermo Fisher Scientific: Thermo Fisher's Analytical Instruments segment includes spectroscopy and process analytical technology used in semiconductor wet chemistry and PV applications. The scale and global service footprint of Thermo Fisher far exceed CI Semi's, but product technology overlaps.
Direct peers
- Onto Innovation: Onto Innovation combines optical metrology, inspection, and process control solutions for semiconductor and adjacent advanced manufacturing. It directly competes with CI Semi in fab process monitoring for both OEMs and end-users.
- Nova Measuring Instruments: Nova (also Israeli) provides optical metrology and process control solutions for semiconductor fabs, including in-situ measurement. It is the closest direct peer to CI Semi in process monitoring, with overlapping target customers (advanced fabs and OEMs).
