Abstract

A far-infrared plane heateris placed in a closed-container-shaped device bodyof an oxidation annealing device, an oxygen addition gas feed pipethrough which an oxygen addition gas containing water vapor and oxygen is fed into the device bodyis connected to a gas exhaust pipethrough which gas in the device bodyis discharged, and jet nozzlesthrough which the oxygen addition gas containing water vapor and oxygen is ejected to an oxygen-deficient portion of a substrateare brought into communication with the oxygen addition gas feed pipe. This allows oxidation annealing of a large substrate at high throughput and low cost while preventing a leakage current.
