SPAD array sensitivity enhancement by diffractive microlens

, 2019
In this paper we present sensitivity improvement of SPAD pixel using diffractive microlens. We designed microlens structures based on rigorous optical simulations, then we developed the process for thick optical spacer and thin amorphous silicon deposition, on which diffractive structures were defined by lithography and etching.
