Abstract:
A system for purifying trichlorosilane that can prevent re-contamination by the dissociation of an adduct occurring in association with the conversion of high boiling point compounds or the remaining of impurities due to an equilibrium constraint is provided. Trichlorosilane containing impurities serving as a donor or an acceptor in silicon crystals is supplied to a multistage impurity conversion step. These impurities in the trichlorosilane are converted into high boiling point compounds in the presence of a distillation aid. A plurality of impurity conversion step sections (10 1  to 10 n ) are connected in series, and any of the impurity conversion step sections comprises a reception section a for the trichlorosilane from the preceding stage section, an introduction section b for the distillation aid, a transmission section c for the trichlorosilane to the subsequent stage section, and a drain section d that discharges a remainder out of the impurity conversion step section.

Claim (Index 7):
The system for purifying trichlorosilane according to  claim 5 , wherein the transmission of the trichlorosilane from which the high boiling point compound is separated to the subsequent stage section is performed in a state of a condensate.
