Reactor and susceptor for chemical vapor deposition process
First Claim
Patent Images
1. A reactor for use in a chemical vapor deposition process comprising:
- (a) a reaction vessel having a gas inlet, a gas outlet and a substantially vertical gas flow path therebetween;
(b) a substantially solid susceptor configured as a truncated wedge, said susceptor comprising a body having a top, a bottom, a pair of longitudinally spaced ends, and a converging pair of opposed faces;
each of said faces having means to receive a plurality of wafers and maintain the wafers exposed to said gas flow path, said susceptor being disposed within said reaction vessel with said opposed faces converging in a direction counter to that of said gas flow path; and
(c) heating means disposed about said reaction vessel for heating said susceptor.

Abstract
A reactor for use in a chemical vapor deposition process occurring in a radiant absorption heater system employs a vertical gas flow reaction vessel and a novel substantially solid susceptor configured as a truncated wedge. The susceptor is characterized by a high utilized area, resulting in a high wafer capacity and low power requirement.
