Abstract: A manufacturing method of a TFT substrate uses a bottom gate structure and the entire process can be completely done with seven masks. The number of masks used is reduced. The manufacturing process of a TFT substrate is simplified. Product yield and increase productivity are effectively improved. By subjecting two ends of a semiconductor pattern to heavy ion doping to form a source electrode and a drain electrode, the manufacturing steps can be reduced and the source electrode and the drain electrode so formed do not need to extend through a via hole formed in an interlayer dielectric layer to get in connection with the two ends of the active layer so as to effectively reduce contact resistance and improve product yield. Also provided is a TFT substrate manufactured with the method.

Abstract: The present invention makes it possible to improve the characteristic of a semiconductor device using a nitride semiconductor. An electrically-conductive film is formed above a gate electrode above a substrate with an interlayer insulation film interposed and a source electrode coupled to a barrier layer on one side of the gate electrode and a drain electrode coupled to the barrier layer on the other side of the gate electrode are formed by etching the electrically-conductive film. On this occasion, the source electrode is etched so as to have a shape extending beyond above the gate electrode to the side of the drain electrode and having a gap (opening) above the gate electrode. Successively, hydrogen annealing is applied to the substrate. In this way, by forming the gap at a source field plate section of the source electrode, it is possible to efficiently supply hydrogen in the region where a channel is formed in the hydrogen annealing process.
