摘要:
There is provided a method for manufacturing a semiconductor device, comprising simultaneously or alternately exposing a substrate, which has two or more kinds of thin films having different elemental components laminated or exposed; and performing different modification treatments to the thin films respectively.
摘要:
Provided is a substrate processing apparatus capable of suppressing accumulation of reaction products or decomposed matters on an inner wall of a nozzle and suppressing scattering of foreign substances in a process chamber. The substrate processing apparatus includes a process chamber, a heating unit, a source gas supply unit, a source gas nozzle, an exhaust unit, and a control unit configured to control at least the heating unit, the source gas supply unit and the exhaust unit. The source gas nozzle is disposed at a region in the process chamber, in which a first process gas is not decomposed even under a temperature in the process chamber higher than a pyrolysis temperature of the first process gas, and the control unit supplies the first process gas into the process chamber two or more times at different flow velocities to prevent the first process gas from being mixed.

摘要:
There are provided an inner tube in which a substrate is stored; an outer tube surrounding the inner tube; a gas nozzle disposed in the inner tube; a gas ejection hole opened on the gas nozzle; a gas supply unit supplying gas into the inner tube through the gas nozzle; a gas exhausts hole opened on the side wall of the inner tube; and an exhaust unit exhausting a space between the outer tube and the inner tube and generating a gas flow in the inner tube toward the gas exhaust hole from the gas ejection hole, wherein the side wall of the inner tube is constituted, so that a distance between an outer edge of the substrate and the gas exhaust hole is set to be longer than a distance between the outer edge of the substrate and the gas ejection hole.
