Abstract

This paper was performed to investigate the characteristic of the Pt-MIS(Metal Insulator Semiconductor) capacitor composed of the LPCVD nitride on the oxide for the hydrogen gas detection. Pt was used as catalytic metal for detecting the hydrogen gas and the flat band voltage shift was measured at various hydrogen concentration and catalytic metal thickness. We found the flat band voltage shift was proportional to the hydrogen concentration and catalytic metal thickness was little effect to the response time.
