Abstract
A semiconductor diode has a blocking electrode for minority carriers constructed in such a manner that the space charge region extends right up to the blocking electrode in the operation state.
Claims21
In a semiconductor delay diode comprising a semiconductor body of a first conductivity type, means, adjacent one surface of said body and including a rectifying junction, for providing a space charge region in said body, and a blocking electrode for minority carriers adjacent the opposite surface of said semiconductor body, the improvement wherein the doping of said semiconductor body and the spacing between said blocking electrode and said junction are such as to extend the space charge region of said diode up to said blocking electrode in the operational state.
A method of producing a semiconductor delay diode comprising the steps of:
- forming a rectifying junction in a semiconductor body of one conductivity type adjacent one surface thereof;
- forming a blocking electrode for minority carriers adjacent the opposite surface of said semiconductor body;
- and, adjusting the thickness of said semiconductor body so that the spacing between said rectifying junction and said blocking electrode for minority carriers is such that the space charge region of said diode extends up to said blocking electrode in the operational state.
