Abstract
Batch thin film capacitors and their methods of manufacture using semiconductor manufacturing techniques. A mask, photo mask or shadow mask, having a pattern is used to form a matrix of rows and columns of thin film capacitors in a wafer. Capacitor terminals are formed in a batch process by separation at column saw areas, depositing a conductive layer and vertically etching horizontal layers of the conductive layer. Capacitance of an individual batch processed thin film capacitor is increased by stacking wafers together prior to separation at the column saw areas and forming capacitor terminals thereafter to couple parallel thin film capacitors together.
