ABSTRACT:
The structure is a semiconductor island with a space etched in the periphery to form two steps. The steps may be characterized as two mesas, a small mesa being located on top of a large mesa. Between the top of the small mesa and the top of the large mesa, a PN junction is located. The edge of the junction is protected by a passivation layer of relatively thick portions of glass deposited adjacent the steps.
