Abstract:
1. A photodiode comprising: a substrate with at least a front side and a back side; at least one PN-junction on the front side; at least one PN-junction on the back side; and at least one conduit for forming an electrical connection from a PN-junction on the front side of the substrate to a PN-junction on the back side of the substrate, wherein the conduit comprises a) a p+ dopant layer and b) a polysilicon or polyimide filling, wherein said photodiode is manufactured from a silicon wafer having a thickness ranging from 0.210-0.260 mm and n-type conductivity, wherein said photodiode is divided into a front-side region and a back side region, wherein each of said front side region and said back side region comprise at least two doped diffusion regions, and wherein at least one doped diffusion region has a depth of approximately 1 μm.
