Patent ID: 8425855

Claim:
A reactor for producing polysilicon, comprising: a first section, wherein at least a portion of the first section has a first composition that comprises: i) at least one first layer, wherein the at least one first layer consists essentially of: at least 37 wt. % nickel and the balance being at least one other metal element; ii) at least one second layer, wherein one layer of the at least one second layer directly contacts one layer of the at least one first layer and the at least one second layer comprises a silicide coating layer; and iii) at least one third layer, wherein one layer of the at least one third layer contacts one layer of the at least one second layer, and the at least one third layer comprises a silicon layer produced from a deposition of silicon element from halogenated silicon source gases within the reactor; a second section, wherein the second section is constructed from a second composition and wherein the first and the second compositions are different; an inert material, wherein the inert material occupies the second section of the reactor, wherein the second section comprises: i) a top portion having a first end and a second end, wherein the second end of the top portion has a first lip and wherein the first end is attached to the portion of the first section of the reactor; ii) a bottom portion having a first end and a second end, wherein the second end of the bottom portion forms the bottom of the reactor and wherein the first end of the bottom portion has a second lip; and wherein the first lip and the second lip are designed to securely attach to each other.
