Integrated semiconductor circuit with two epitaxial layers of different conductivity types. |
摘要 |
<p>An integrated semiconductor circuit comprises an inner layer (2) of semiconductor material of one conductivity type contiguous with a substrate layer (3) of semiconductor material of the opposite conductivity type and an outer layer (1) of semiconductor material of the opposite conductivity type contiguous with the inner layer. There are a first ohmic contact (6) to a first region of the outer layer, a second ohmic contact (8) to a first region of the inner layer, and a third common ohmic contact (9) to both a second region of the outer layer and a second region of the inner layer. Control means (12) varies conduction between the first and second regions of the outer layer whereby conduction between the first and second regions of the inner layer is varied.</p> |
