Title: Vapor growth device
Inventor: YUKI AKIMASA
IPC: H01L21/31
Filed: 1991-04-17
Abstract: PURPOSE:To reduce the wake flow side of a reaction chamber and a deposit on an exhaust pipe, and to grow a film uniformly on a wafer by installing a cylinder on the wafer-row wake flow side in the reaction chamber. CONSTITUTION:When a reaction chamber 1 heated at approximately 700 deg.C is supplied with tetraethyl oxide silicon from a gas feed pipe 3, one part of the gas is decomposed, and thin films are formed onto a wafer row 5. The decomposed gas containing residual tetraethyl oxide silicon is flowed through an exhaust pipe 4 through the clearance of a cylinder 10 and the reaction chamber 1. Since the retention time of the decomposed gas is shortened at that time, the generation of a wasteful precursor by the decomposition of tetraethyl oxide silicon in the wake flow of the wafer row 5 is inhibited, thus reducing the wake flow of the reaction chamber 1 and a deposit 9 on the exhaust pipe 4. Since the sectional area of the path of the inside of a furnace is narrowed, the diffusion travel speed of the film precursor to the exhaust pipe 4 is suppressed, thus equalizing the concentration of the film precursor on the wafer row 5, then realizing a uniform film growth rate.
