Abstract
A single junction interdigitated photodiode utilizes a stack of alternating highly doped first regions of a first conductivity type and highly doped second regions of a second conductivity type, which are formed below and contact the first regions, to collect photons. In addition, a highly doped sinker of a first conductivity type contacts each first region, and a highly doped sinker of a second conductivity type contacts each second region.
