Experimental process system development unit for producing semiconductor-grade silicon using the silane-to-silicon process. Quarterly progress report, October-December 1979

Description: This program consists of the engineering design, fabrication, assembly, operation, economic analysis, and process support R and D for an Experimental Process System Development Unit (EPSDU). EPSDU equipment specification, vendor development, and evaluation of quotations represent a significant effort which will permit the start of ordering EPSDU equipment during the next quarter. Initial mini-burner test results are encouraging. It appears that a fairly simple and cost-effective waste treatment… more

Experimental process system development unit for producing semiconductor-grade silicon using the silane-to-silicon process. Quarterly progress report, July-September 1979

Description: Progress on the engineering design, fabrication, assembly, operation, economic analysis, and process support R and D for an Experimental Process System Development Unit (EPSDU) is reported. A preliminary P and I diagram, layout, and electrical one-line were completed, and are being reviewed. Specifications for all major equipment were prepared and the equipment request for quotations was submitted to potential vendors. A small waste treatment apparatus was assembled to provide essential informa… more

Low Cost Solar Array Project: experimental process system development unit for producing semiconductor-grade silicon using the silane-to-silicon process. Quarterly progress report, April-June 1979

Description: The overall objective of the LSA Silicon Material Task is to establish a chemical process for producing silicon at a rate and price commensurate with the production goals of the LSA project for solar-cell modules. This material must be suitable for utilization in the large-area sheet process and in the automated process for the fabrication of solar cells. As part of the overall Silicon Material Task, Union Carbide developed the silane-silicon process and advanced the technology to the point tha… more

Low Cost Solar Array Project. Feasibility of the silane process for producing semiconductor-grade silicon. Final report, October 1975-March 1979

Description: The commercial production of low-cost semiconductor-grade silicon is an essential requirement of the JPL/DOE (Department of Energy) Low-Cost Solar Array (LSA) Project. A 1000-metric-ton-per-year commercial facility using the Union Carbide Silane Process will produce molten silicon for an estimated price of $7.56/kg (1975 dollars, private financing), meeting the DOE goal of less than $10/kg. Conclusions and technology status are reported for both contract phases, which had the following objectiv… more
