Abstract:
A process of forming a light-receiving device type of avalanche photodiode (APD) is disclosed. The process includes steps of: (1) growing semiconductor layers on a semiconductor substrate, the semiconductor layers providing a first area on a top thereof; (2) thermally diffusing impurities within the semiconductor layers in a second area outside of the first area so as to leave a roughed surface in a top of the second area, the impurities laterally diffusing to form an diffusion edge locating inside of the first area; and (3) removing the semiconductor layers including the roughed surface thereof in the second area to form a mesa in the first area, the mesa including the diffusion edge in a periphery thereof but excluding the roughed surface.
