Imec has presented a prototype high-resolution short-wave-infrared (SWIR) image sensor with record small pixel pitch of 1.82 µm. It is based on a thin-film photodetector that is monolithically integrated on a custom Si-CMOS readout circuit.

A fab-compatible process flow paves the way to high-throughput, wafer-level manufacturing. The presented technology largely exceeds the capabilities of today’s InGaAs-based SWIR imagers in terms of pixel pitch and resolution, with disruptive cost and form factor
