CONDENSATION AND NUCLEATION PROCESSES OF SINGLE CRYSTAL THIN FILMS.
Abstract
Theoretical and experimental investigations were conducted to evaluate those parameters which affect the nucleation, condensation, and subsequent growth rates of single crystal thin films. In the theoretical program, the path probability method was used to study the process of the film growth, with the particular objective of obtaining more reliable results than those reported previously. In the experimental program, single crystal silicon films were deposited on selected areas of fused quartz substrates using vapor-liquid solid techniques in conjunction with moving-mask-growth (VLS-MMG). Silicon single crystal areas ranging from 100 to 300 microns in lateral dimension were prepared at substrate temperatures from 800 to 900C. Optical and electron microscope and electron transmission diffraction observations were made of typical film sample areas. A vacuum system with a stainless steel chamber was set up for experiments so that slower rates of silicon deposition and mask motion could be achieved.
