Title: Semiconductor device
Inventor: KAWAURA HISAO
IPC: H01L29/423
Filed: 1993-09-27
Abstract: PURPOSE:To prevent a secondary hot carrier, by using a gate electrode made of material that transmits near infrared ray and visible light. CONSTITUTION:After a gate oxide film 4 is formed on a semiconductor substrate 1, an ITO film for forming a gate electrode is deposited thereon by sputtering. The ITO film is wet-etched to form a gate electrode 5A. Hot carriers are generated in a high electrostatic region near a junction part between a drain 3 and the substrate 1, and part of hot carriers are recombined and changed into photons 6. The energy band of photons 6 ranges from the near infrared radiation to the visible light. Since the gate electrode 5A transmits the nearly infrared ray and the visible light, part of photons 6 that reach a transparent gate electrode 5A are not reflected, and there almost all photons are passed through the gate electrode 5A. Consequently, secondary hot carriers produced by photons reflected from the gate electrode can be prevented.
