摘要：
Embodiments of the disclosure provide a method for forming an optical sensing device for a receiver in an optical sensing system. According to the method, a light concentrator is formed in a carrier wafer. The carrier wafer is bonded with a detector wafer. The detector wafer has a photodetector such that the light concentrator aligns with and covers the photodetector. A portion of the carrier wafer is removed to expose the light concentrator and the photodetector.
