불화물 게이트 절연막을 이용한 반전형 GaAs MISFET

The GaAs Inversion-type MISFET using Fluoride Gate Insulator

The interface properties of Fluoride/GaAs structures were investigated. It was foung that rapid thermal annealing(RTA) typically 800-850$^{\circ}C$for 1 min, was useful for improving the interface properties of that structures. The analysis by means of SIMS indicated that interdiffusion of each constitutional atom through the interface was negligible. The interfacial atom bonding model for RTA treatment was proposed. Bases on these results, inversion-type GaAs MISFET was fabricated using standard planar technologies.
