SI Sensors

Custom CMOS image sensor design forms the core of SI Sensors’ work as a division of Specialised Imaging. It develops sensors for its parent’s next generation of ultra-fast imaging cameras and for external customers, including space and defence applications. Its semiconductor activities include developing in-house intellectual property, selecting foundry technologies, designing bespoke sensor packages and conducting electro-optical testing from characterisation through to mass production. Package design addresses custom electrical, mechanical and thermal interfaces, while testing references EMVA 1288 and ESCC 9020. Available technologies include low-noise CMOS, back-side illumination, high dynamic range, global shutters, CCD-in-CMOS pixels and reticle stitching. The team also offers non-visible imaging techniques and system-on-chip sensor architectures, using CMOS process nodes from 180 nm to 65 nm. The supplied pages provide a UK telephone contact but do not identify a UK headquarters or facility address.

Primary capability: Detectors / Imaging Devices. Supply-chain role: Custom image sensor design, Sensor package development, Sensor characterisation and testing.
