AC Plasma-Assisted Chemical Vapor Deposition of Cubic Silicon Carbide on Silicon Substratetrate temperature of 750 °C-1150°C. When the ratio of SiH. to CH. (Si/C) increases, the structures of films changed from amorphous to polycrystalline loaded with excess Si at a low substrate temperature less than 1000° C, reflecting a Si radical steeply increases and a H radical is saturated. Excess

Hall Effect and Infrared Absorption Measurements on Nitrogen Donors in 6H-SiCctral regions from 400 to 700 cm. and 1000 to 1250 cm.. The observed lines are assigned to electronic transitions of nitrogen donors residing at three inequivalent lattice sites (h,k.,k.). A valley-orbit splitting of the ground state of 12.6 meV is determined for nitrogen donors on hexagonal sites;

Growth of Cubic Silicon Carbide on Silicon Using the C2HCl3-SiH4-H2 Systemf large-area 3C-SiC on other materials, e.g. silicon[l–5], has become extensively used. With a 20% lattice mismatch between the 3C-SiC layer and the Si substrate the growth of good-quality epitaxial layers presents considerable technological difficulties.

A dramatic improvement in film thickness uniformity was observed at low pressure, resulting in a standard deviation of less than 5% over an entire 7.5 cm diameter wafer.

By simultaneous chemical vapor deposition growth on well-oriented 6H-SiC(0001) and 15R-SiC(0001), the prediction was experimentally verified.
