Claim Text:
1. An electrical device comprising: a first layer of a first conductivity type; a second layer of a second conductivity type opposite to the first conductivity type; and an intrinsic layer arranged between the first and second layers, wherein the intrinsic layer has a reduced thickness at at least one portion, wherein an area of the at least one portion is less than 30% of an active area in which the first and second layers face each other, wherein the at least one portion of the reduced thickness is formed by one or more indenters having the second conductivity type, wherein the one or more indenters are electrically connected to the second layer and extend into the intrinsic layer, and wherein the one or more indenters are arranged in deep trenches so as to form a pin-junction between the one or more indenters and the first layer with the intrinsic layer in-between.
