A method of manufacturing an inverse-staggered self-aligned thin film transistor on a substrate having a front surface and a back surface is provided. The method includes the steps of (a) forming a gate electrode over the front surface of the substrate,(b) forming a gate insulating layer over the gate electrode,(c) forming a semiconductor active layer over the gate insulating layer adjacent the gate electrode.
