Sensor Packaging and Integration Lab

The Sensor Packaging and Integration Laboratory (Sensor Lab) is a dedicated hardware hub supporting full research and development processes of micro/nano sensors and associated devices, including sensor chip/devices fabrication and pilot runs, packaging, and testing.

Two locations equipped with Class 100/1000/10000 cleanroom space are offered to users for conducting research and product development. Apart from fully furnished cleanroom facilities, HKSTP and our partners also provide common wafer processing tools (including deposition, patterning, etching, packaging and characterisation), technical support and consultation services.

We also welcome R&D partners to formulate government-funded technology projects that would utilize the laboratory service as part of the pilot production.
