IMPROVEMENTS IN OR RELATING TO HIGH VOLTAGE SEMICONDUCTOR DEVICES |
摘要 |
Two gaps are placed in the reflowed phosphorus-doped silicon dioxide material overcoating of a planar high voltage semiconductor device to prevent polarization of the reflowed silox. The invention is applicable to any device using a polarizable glassy coating which will be exposed to a high electric field extending along its surface and is shown applied to a high voltage diode, a high voltage MOSFET and a high voltage TRIMOS-type device which is a semiconductor switching device using spaced MOS transistors having a common drain region. |
