Abstract:
A method of manufacturing an active matrix device including at least an inverted stagger type thin film transistor, said method comprising the steps of:forming at least a gate line comprising aluminum over a substrate; forming a gate insulating film on a portion of the gate line; forming an amorphous semiconductor film comprising silicon on the gate insulating film; forming a source region, a drain region and a channel region between the source and drain regions in the amorphous semiconductor film; forming at least a data line over the substrate; forming a leveling film comprising an organic material to provide a leveled upper surface; forming a conductive film on the leveling film; forming a photoresist on the conductive film to pattern the conductive film; irradiating the substrate from a back side thereof with a light using the gate line and the data line as a mask to pattern the conductive film in order to form at least a pixel electrode being electrically connected to one of the source and drain regions, wherein a periphery of the pixel electrode is defined in a self-alignment manner with respect to the gate and data lines.
