Abstract
An integrated circuit includes a semiconductor substrate with a semiconductor surface layer having a first conductivity type and a top surface, a diode including a buried region within the surface layer, the buried region having an opposite second conductivity type and being spaced apart from the top surface by a portion of the semiconductor surface layer having the first conductivity type, a dielectric layer over the surface layer, and a metal layer located over the dielectric layer and including an aperture extending laterally in a first direction over the semiconductor surface layer and laterally spaced apart from the buried region in a second direction.
