Abstract
An improved process of making a ferroelectric electronic component, such as a non-volatile RAM or an electro-optic switching array, is disclosed. The process essentially includes the separate formation of two subassemblies and then connecting them by placing one on top of the other. Electrical contacts are made by 'bumping' or other 'flip chip' techniques.
