A silane-based polysilicon process
Abstract
A silane based polysilicon process plant was constructed in Miami, Oklahoma. The processes included: the synthesis of crude silane gas, ultrapurification of the gas, and direct pyrolysis to product silicon. Features of the process provided for direct continuous operation from process feed to final product, without the requirement to store intermediates or even convert the silane to a liquid phase. Semiconductor product quality as analyzed internally was demonstrated by the first integrated operation of the plant.
