  • Method for fabricating multilayer insulator-semiconductor memory apparatus
    Patent number: 3964085
    Abstract: An SI.sub.1 I.sub.2 M (semiconductor-insulator.sub.1 -insulator.sub.2 -metal) memory structure, containing an impurity such as tungsten concentrated in a region including the interface ("I.sub.1 I.sub.2 ") region between the I.sub.1 and I.sub.2 region, is fabricated by depositing an oxide of the impurity, such as tungsten trioxide, on the then exposed, I.sub.1 layer prior to fabricating the I.sub.2 layer. The oxide of the impurity, such as tungsten trioxide, can be advantageously deposited by means of reactive evaporation.
