摘要
New chemical vapour deposition (CVD) processes controlled by light irradiation are studied and applied to III-V semiconductor device technology. The interactions between the incident photons and the gas-substrate system are either photolytic (UV lamps) or pyrolytic (IR lamps). In the first case the process is cold and in the second one it produces fast thermal ramping. The technique is thus compatible in both cases with the fragile semiconductor substrate and it allows in-situ processing. We report here a set of results involving surface and interface studies in order to prepare the deposition of thin-film materials, thin dielectric film deposition using "flash" CVD or UVCVD, and the first attempts to deposit semiconductors and metals using the same "flash" CVD techniques. the aim of this work is to propose alternative technologies for III-V semiconductors. © 1990.
