Infrared sensor for CVD deposition of dielectric films( Book )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

Infrared emission (IRE) spectra were obtained from two borophosphosilicate glass (BPSG) thin-film sample sets. The first set consisted of 21 films deposited on undoped silicon wafers, and the second set consisted of 9 films deposited on patterned and doped (product) wafers. The IRE data were empirically modeled using partial least-squares calibration to simultaneously quantify four BPSG thin-film properties. The standard errors of the determinations when modeling the 21 monitor wafers were <O.l wt % for boron and phosphorus content, 36 [angstrom] for film thickness, and 1.9[degree]C for temperature. The standard errors of the determinations based on the product wafers were 0.13 wt % each for B and P content, 120 [angstrom] for film thickness, and 5.9 C for temperature
The Vibrational Spectra of Solid Fluorine( Book )

1 edition published in 1973 in English and held by 1 WorldCat member library worldwide

Raman and far infrared spectra of crystalline fluorine have been obtained in both solid phases. As expected for the disordered higher temperature form, only the Raman-active stretching fundamental is observed for beta-F2. The predictions of a preliminary calculation of the optically active lattice frequencies for the low temperature phase are in poor agreement with the observed lattice frequencies, suggesting that an improved model will be required to help distinguish the correct alpha-F2 crystal structure. Solid fluorine more closely resembles oxygen than it does the other halogens. In particular, the intermolecular forces are extremely weak, as exemplified by the small shifts of the internal frequencies from their gas phase values, the absence of observable factor group splitting of the fundamental and the overtone, and the relatively low values of the external (lattice) frequencies.

Trace water vapor detection in nitrogen and hydrogen chloride gases by FTIR spectroscopy( Book )

1 edition published in 1994 in English and held by 0 WorldCat member libraries worldwide

An optical instrument for the determination of trace H[sub 2]O in N[sub 2] and HCl gases has been built. It is based on a commercial Fourier transform infrared spectrometer, a long-path gas cell, and classical least squares data analysis. The optimum instrumental parameters havve been determined. Particularly important is the finding that maximal precision is obtained at low resolution, implying that future instruments may be based on less expenisve, low-resolution spectrometers. A calibration over the range of 40 to 1800 ppb has been performed and found to be in good agreement with published spectral data. Also, detection limits have been shown to be about 10 ppb
