Abstract
A high voltage thin film transistor structure and method are disclosed which make it possible to fabricate matrix displays with integrated pixel switches on PLZT substrates. A polysilicon transistor capable of withstanding more than 60 V across the source and drain and with a ratio of on to off current in excess of 10.sup.3 is disclosed. The fabrication method disclosed is suitable for use with brittle and readily oxidizable PLZT substrates.
