MICROWAVE PLASMA CVD SYSTEM FOR THE FABRICATION OF THIN SOLID FILMS.

THIS STUDY WAS CONCERNED WITH THE DEVELOPMENT OF A PROCESS FOR THE DEPOSITION OF THIN-FILMS FROM A MICROWAVE PLASMA OF SEMICONDUCTOR MATERIALS. A COAXIAL LINE TYPE MICROWAVE CW DISCHARGE WAS USED TO CREATE UNIFORM PLASMAS, AND A-SI FILMS WERE FABRICATED FROM AR GAS CONTAINING 10PSIH//4. THE X-RAY DIFFRACTION PATTERNS SHOWED THAT THE FABRICATED FILMS, WHERE THE MICROWAVE POWER IS LARGE, ARE CRYSTALLIZED AND THE STRUCTURE OF THE OTHER FILMS IS AMORPHOUS. THE RESULTS ARE APPLICABLE TO SOLAR CELL MANUFACTURE.
