Abstract

A method of manufacture of thin film, field-effect transistors formed on a transparent substrate and with transparent, conductive source and drain electrodes, uses initially deposited gate electrodes as a mask in association with photolithographic processing using radiation transmitted through the substrate and electrodes to minimize parasitic capacitance between the gate and source and drain electrodes.
