Abstract
A conductive trace is formed over and insulated from a region of semiconductor material, such as a region adjacent to the n+ region of an n+/p− photodiode, and a sawtooth current is made to flow through the conductive trace. The sawtooth current induces charge carriers to move through the semiconductor material to a collection region in the semiconductor material.
Claims11
A method of inducing charge carriers to move through a semiconductor material to a collection region in the semiconductor material, a conductive trace being formed over and insulated from the semiconductor material, the method comprising the step of making a sawtooth current flow through the conductive trace, the sawtooth current inducing charge carriers to move through the semiconductor material to the collection region.
