Abstract
An improved semiconductor device is disclosed which is free from current leakage due to pin-holes or other gaps. Also an improved method for provessing a semiconductor device is shown. According to the invention, gaps produced in fabricating process of the semiconductor layer are filled with insulator in advance of deposition of electrodes. By virtue of this configuration, short current paths do not result even if transparent electrode is provided on the semiconductor layer.
