What Toho Technology does

Toho Technology Inc. is the Chicago, Illinois-based US subsidiary of Japan's Toho Group, a Nagoya-headquartered conglomerate with roots dating to 1819. The company manufactures and distributes precision industrial metrology and wet process equipment serving semiconductor fabs, flat panel display (FPD) manufacturers, and glass producers. Its metrology portfolio spans thin film stress measurement (FLX Series with automated FLX-2320-L variant, based on KLA-Tencor-transferred dual-wavelength laser scanning technology), film thickness (TohoSpec 3100, originally Nanometrics), Hall Effect measurement (HL9900), electrochemical CV profiling (ECVPro+), contact and optical profilometry (FP and FPM Series, the latter from Zygo), four-point probe resistivity, CV mapping, and Seebeck effect measurement. The wet process division delivers precision cleaners, etchers, and strippers for display and architectural glass substrates, with 300+ precision cleaners shipped and quantified sub-micron particle removal performance. An automation product line rounds out the offering with PLC migration adapters, multiplexing systems, relay boxes, interface terminals, and terminal blocks. The company also runs ISO 9001/14001-certified contract manufacturing for complex electromechanical assemblies across US, China, Japan, and Indonesia sites.

The business model rests on one-time capital equipment sales (quote-based, no public pricing) supplemented by recurring service, maintenance, and annual support contracts delivered through direct technicians in the Americas, Japan, China, and Indonesia and certified distributor service professionals worldwide. Go-to-market is hybrid: direct enterprise field sales in North America via a Chicago-based Technical Account Manager model targeting process engineers, combined with a network of exclusive and non-exclusive regional distributors covering Europe, India, Korea, China/HK, Israel, and Southeast Asia. The company sells across three primary customer segments — semiconductor and microelectronics manufacturers (HB-LED, compound semiconductor, strained silicon, SOI), FPD manufacturers (color filter, TFT, ODF, photo spacer lines), and industrial glass manufacturers (display, architectural, dynamic, medical imaging sensor substrates) — with a horizontal segmentation approach. Distribution partnerships include Kateeva (OLED) and Kramer Sonic Industries (SAM), while the CERTUS sub-brand extends into food safety following a 2016 pathogen detection technology license.
