ABSTRACT:
A process for fabricating magnetic bubble domain devices having multiple layers. The process is a single high resolution mask process. A magnetizable layer, a conductive layer and at least one dielectric spacer layer are provided on a suitable magnetic bubble domain material and etched in a suitable manner such as by ion milling. The material layers may be applied such that the conductive layer is applied first and the magnetizable layer applied thereafter or vice versa.
