What IceMos Technology does
IceMOS Technology Ltd is a privately-held specialty semiconductor company headquartered in Belfast, Northern Ireland, with 51-100 employees and over 20 years of experience in thick-film SOI manufacturing. The company develops and manufactures two principal product lines: (1) Superjunction MOSFETs, built using a proprietary process that combines Silicon MOSFET technology with MEMS process technology to break the traditional 'Silicon Limit' and achieve high voltage (600V-730V) with low on-resistance; and (2) Engineered Silicon Substrates, including SOI, SiSi, DSOI, DSP, CSOI, Thin SOI, TSOI, and TSV wafers in 100-200mm diameters for IC and MEMS applications. The latest product, mSJMOS™, extends the superjunction MOSFET portfolio.
IceMOS operates a hardware-sales revenue model with two pricing tracks: standardized $299/wafer unit pricing for inventory items (SOI, SiSi, DSOI, DSP, substrates) and quote-based pricing for custom MOSFET products and foundry services. Lead times for inventory items are 2-4 weeks. The go-to-market is enterprise field sales: four direct regional sales teams covering North America, Europe, China, and Japan, augmented by a network of eight authorized distributors spanning the US, Europe, Israel, Brazil, China, and Japan. Customers span power electronics, automotive (supported by IATF 16949:2016 certification), IT hardware, and IC/MEMS applications.
In April 2025 the company closed a $22 million Series E funding round led by 57 Stars to fund the mSJMOS launch and Northern Ireland expansion, followed by the December 2025 opening of a regional office at Hong Kong Science Park to support global semiconductor business and customer support. IceMOS holds ISO 9001:2015 and ISO 14001:2015 certifications alongside its automotive quality certification, and sells through both direct sales and a global distributor channel.
