Abstract

An improved chemical vapor deposition method for depositing transparent continuous coatings of sp[sup 3]-bonded diamond-type carbon films, comprises: (a) providing a volatile hydrocarbon gas/H[sub 2] reactant mixture in a cold wall vacuum/chemical vapor deposition chamber containing a suitable substrate for said films, at pressure of about 1 to 50 Torr; and (b) directing a concentrated solar flux of from about 40 to about 60 watts/cm[sup 2] through said reactant mixture to produce substrate temperatures of about 750 C to about 950 C to activate deposition of the film on said substrate. 11 figs.

High rate chemical vapor deposition of carbon films using fluorinated gases

Patent Stafford, Byron L [Arvada, CO]; Tracy, C Edwin [Golden, CO]; Benson, David K [Golden, CO]; ...

A high rate, low-temperature deposition of amorphous carbon films is produced by PE-CVD in the presence of a fluorinated or other halide gas. The deposition can be performed at less than 100.degree. C., including ambient room temperature, with a radio frequency plasma assisted chemical vapor deposition process. With less than 6.5 atomic percent fluorine incorporated into the amorphous carbon film, the characteristics of the carbon film, including index of refraction, mass density, optical clarity, and chemical resistance are within fifteen percent (15%) of those characteristics for pure amorphous carbon films, but the deposition rates are high.

Diamond nucleation on unscratched silicon substrates coated with various non-diamond carbon films by microwave plasma-enhanced chemical vapor deposition

Journal Article Feng, Z [Department of Mechanical Engineering, University of California, Berkeley, California 94720 (United States)]; Brewer, M A [Lawrence Berkeley Laboratory, University of California, Berkeley, California 94720 (United States)]; Komvopoulos, K [Department of Mechanical Engineering, University of California, Berkeley, California 94720 (United States)]; ... - Journal of Materials Research; (United States)

The efficacy of various non-diamond carbon films as precursors for diamond nucleation on unscratched silicon substrates was investigated with a conventional microwave plasma-enhanced chemical vapor deposition system. Silicon substrates were partially coated with various carbonaceous substances such as clusters consisting of a mixture of C[sub 60] and C[sub 70], evaporated films of carbon and pure C[sub 70], and hard carbon produced by a vacuum arc deposition technique. For comparison, diamond nucleation on silicon substrates coated with submicrometer-sized diamond particles and uncoated smooth silicon surfaces was also examined under similar conditions. Except for evaporated carbon films, significantly higher diamond nucleation densitiesmore »« less

Effect of graphitic carbon films on diamond nucleation by microwave-plasma-enhanced chemical-vapor deposition

Journal Article Feng, Z; Komvopoulos, K [Department of Mechanical Engineering, University of California, Berkeley, California 94720 (United States)]; Brown, I G [Lawrence Berkeley Laboratory, University of California, Berkeley, California 94720 (United States)]; ... - Journal of Applied Physics; (United States)

Diamond nucleation on very smooth (100) silicon substrates coated with thin films of a colloidal graphite suspension was investigated with a microwave-plasma-enhanced chemical-vapor-deposition system. Nucleation densities of the order of 10[sup 6] cm[sup [minus]2] were obtained by coating the substrates with carbon films of thicknesses less than 1 [mu]m. However, very low nucleation densities were obtained with carbon film thicknesses greater than 1 [mu]m. The effect of the carbon film thickness on diamond nucleation was examined by measuring the etching rate of carbon films exposed to a hydrogen plasma and was further interpreted on the basis of scanning electron microscopymore »« less
