Abstract
A monolithic, vertical, planar semiconductor structure with a number diodes having different intrinsic regions is described. The diodes have intrinsic regions of different thicknesses as compared to each other. In one example, the semiconductor structure includes an N-type silicon substrate, an intrinsic layer formed on the N-type silicon substrate, and a dielectric layer formed on the intrinsic layer. A number of openings are formed in the dielectric layer. Multiple anodes are sequentially formed into the intrinsic layer through the openings formed in the dielectric layer. For example, a first P-type region is formed through a first one the openings to a first depth into the intrinsic layer, and a second P-type region is formed through a second one of the openings to a second depth into the intrinsic layer. Additional P-type regions can be formed to other depths.
