Abstract:
1. A vertical type semiconductor device producing apparatus, comprising: a vertical type reaction chamber which is to accommodate a plurality of stacked substrates; an exhaust path which exhausts said reaction chamber; a vacuum exhaust device which exhausts said reaction chamber through said exhaust path; an exhaust valve which opens and closes said exhaust path; a first supply path which supplies a first kind of gas, which contributes to film formation, to said reaction chamber; a second supply path which supplies a second kind of gas, which contributes to said film formation, to said reaction chamber; first and second gas supply valves which respectively open and close said first and second supply paths; and a controller which controls said exhaust valve and said first and second gas supply valves such that when said first kind of gas is supplied to said reaction chamber, said first kind of gas is supplied to said reaction chamber from said first supply path in a state in which exhaust of said reaction chamber is being stopped to expose said plurality of substrates in said reaction chamber to said first kind of gas, and when said second kind of gas is supplied to said reaction chamber, said second kind of gas is supplied to said reaction chamber through said second supply path in a state in which said reaction chamber is being exhausted by said vacuum exhaust device to expose said plurality of substrates in said reaction chamber to said second kind of gas.
