ABSTRACT. In the Siemens method, high-purity Si is produced by reducing SiHCl 3 source gas with H 2 ambient under atmospheric pressure. Since the pyrolysis of SiHCl 3, which produces SiCl 4 as a byproduct, occurs dominantly in the practical Siemens process, the Si yield is low (~30%). In the present study, we generated hydrogen radicals …
