What Gazer does

Gazer (盖泽科技) is a China-based developer of optical metrology equipment and precision sensors for the semiconductor and industrial automation industries, founded around 2019 and headquartered in Shanghai's Putuo district with a subsidiary in Suzhou. The company sells three product families: front-end semiconductor metrology equipment (IR-series FTIR film thickness, OL-series overlay metrology, EC-series FTIR element concentration, EP-series ellipsometric film thickness, IDI/ID300-series internal stress analysis, and IS-series wafer inspection); semiconductor components (EA-series Aligner wafer calibrators, WR-series wafer ID readers using deep-learning OCR, and GS-99 laser-driven xenon plasma light sources); and industrial sensors (EM/LM/WM-series edge measurement sensors and S3-series laser displacement sensors). Technology is anchored on 100% self-developed core optical components, AI-powered intelligent vision and autonomous learning algorithms, and 97 accumulated patents spanning FTIR, ellipsometry, stress analysis, and vector Bessel beam micro-nano displacement.

Gazer monetizes primarily through one-time hardware sales of equipment and components to enterprise customers — semiconductor fabs, listed wafer companies, state-owned semiconductor enterprises, and lithium battery / new energy manufacturers including CATL — via a direct enterprise field-sales motion in China. The company supplements equipment sales with participation in SEMICON China and SEMI committee meetings, its company website, and a WeChat official account for demand generation. R&D and product expansion are funded by venture capital, with four disclosed funding rounds between May 2023 and December 2025 (cumulative ~$14M disclosed) led by a syndicate of state-affiliated, university-linked, and specialist investors. Strategic partnerships with Fudan University and Academician Zhuang Songlin's team at Shanghai University of Technology anchor the talent and research pipeline.
