SEMICONDUCTOR DEVICE, METHOD FOR MANUFACTURING THE SAME, LIQUID CRYSTAL TELEVISION AND EL TELEVISION

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device having a high withstand voltage and a high step coverage property of a gate insulating layer by a manufacturing method with a small number of processes and high usability of materials. SOLUTION: A method for manufacturing a semiconductor device comprises the steps of: forming a plurality of first conductive layers over a substrate, forming a first insulating layer to fill the gaps of the plurality of the first conductive layers, forming a second insulating layer over the first insulating layer and the plurality of the first conductive layers, and forming a semiconductor region and a second conductive layer over the second insulating layer.
