HALVLEDARDON INNEFATTANDE BL A ETT PASSIVISERINGSSKIKT AV POLYKRISTALLINT KISEL SOM INNEHALLER SYRE

摘要

A semiconductive device is provided which includes a single crystal substrate. A first insulating layer arranged on one surface of the substrate is of polycrystalline silicon containing oxygen. A second insulating layer formed on the first insulating layer is of polycrystalline silicon containing one of a group consisting of nitrogen, Si3N4, Al2O3 and silicone resin. The substrate includes at least one PN junction which extends to the said surface of the substrate. A novel method of making is also disclosed.
