  • Method of fabricating an avalanche photodiode employing single diffusion
    Patent number: 11837681
    Abstract: An avalanche photodiode with a diffused junction and the method for its fabrication are disclosed. The method comprising forming, on a substrate, a first high-doped region and a low-doped region; performing selective area growth (SAG) with in-situ etchant on the low-doped region to grow a SAG structure; and diffusing through the SAG structure to form a second high-doped region in the low-doped region.
    Type: Grant
