Abstract
Very thin uniform silicon nitride films less than 100A have been obtained on silicon wafers by direct thermal reaction with nitrogen at temperatures ranging from 1200° to 1300°C. Small amounts of water or oxygen in reaction mixture caused vapor etching which gave rise to local crystallization. By eliminating both from the reaction ambient to less than 1 ppm, amorphous silicon nitride films can be deposited. These films have been found to have properties similar to those of CVD by investigations of Auger electron spectroscopy, infrared spectroscopy, and ellipsometry. Remarkable masking effects of the films against oxidation and phosphorus diffusion have been found.

Thermal nitridation of Si and SiO 2 for VLSI

TL;DR: In this paper, the authors present an extensive review of thermal nitridation of Si and SiO 2, and show that very thin thermal silicon nitride and nitroxide films can be used as gate dielectrics for future highly scaled-down VLSI devices.

Atomic transport during growth of ultrathin dielectrics on silicon

TL;DR: In this article, an atomic transport in thermal growth of thin and ultrathin silicon oxide, nitride, and oxynitride films on Si is reviewed and the physico-chemical constitution of the involved surfaces and interfaces for each different dielectric material, as well as complementary studies of the gas, gas-surface, and solid phase chemistry.

Rapid thermal annealing of polysilicon thin films

TL;DR: In this article, changes in the stress level due to rapid thermal annealing of polycrystalline silicon thin films were studied as a function of the time and temperature, and the corresponding variations in the microstructure and surface layer were experimentally investigated by a variety of analytical tools.

Characterization of low‐pressure chemical‐vapor‐deposited and thermally‐grown silicon nitride films

TL;DR: In this article, low pressure chemical vapordeposited (LPCVD) silicon nitride films on silicon have been characterized by means of Rutherford backscattering (RBS), Auger electron spectroscopy (AES) combined with ion sputtering, and spectroscopic ellipsometry.
