High speed photodiode with a barrier layer for blocking or eliminating slow photonic carriers and method for forming same |
摘要 |
A structure (and method for forming the structure) includes a photodetector, a substrate formed under the photodetector, and a barrier layer formed over the substrate. The buried barrier layer preferably includes a single or dual p-n junction, or a bubble layer for blocking or eliminating the slow photon-generated carriers in the region where the drift field is low.
