What SemiDice does
SemiDice is a global distributor of bare semiconductor die and wafers and a provider of value-added wafer processing services, headquartered in Los Alamitos, California with a European operation in Norwich, UK. Founded in 1976 and operating as an independent subsidiary of Micross Components since June 2021, the company serves aerospace, defense, space, medical, and industrial customers through two organizational divisions: a Hi-Rel Division dedicated to military, space, and life-support applications (offering Class H, K, and T lot acceptance testing per MIL-PRF-38534), and a Standard Products Division for commercial and industrial high-volume orders. Its customer base spans Class K space programs, defense and aerospace contractors, medical device manufacturers, and commercial/industrial die users.
The company's core technology centers on wafer processing up to 12 inches (mapping, inking, sawing, dicing, visual inspection, die loading), wafer re-probing with hot chuck capability, Class H/K/T lot acceptance testing, and long-term die storage. SemiDice maintains authorized or sole-source distribution rights with 45+ semiconductor manufacturers including Analog Devices, Wolfspeed, ON Semiconductor, Texas Instruments, Microchip/Microsemi, Vishay, Central Semiconductor, Navitas, and Microdul. It holds AS9100, ISO 9001:2015, ITAR (valid through 2026), and ANSI/ESD S20.20-2021 certifications, qualifying it for high-reliability defense and space supply chains.
SemiDice generates revenue through two primary streams: (1) one-time sales of bare die and wafer products from franchised manufacturer lines, and (2) professional services revenue from wafer processing, lot acceptance testing, and long-term die storage. Pricing is quote-based with no public disclosure; customers engage via B2B inside sales, dedicated field account management, and an online RFQ system capturing industry vertical and country information. Go-to-market is enterprise B2B with multi-year contract cadence, supported by direct US sales, SemiDice Europe for EMEA/APAC coverage, and access to parent Micross's broader component modification, packaging, and reliability testing portfolio.
