Abstract: A gate valve apparatus is disclosed. The gate valve apparatus is provided with a valve casing that includes a first valve seat and a second valve seat, and in which an opening portion is formed; and a closure element that includes a sealing member that contacts the first valve seat to seal the opening portion. In addition, the gate valve apparatus is provided with a shutoff member that contacts the second valve seat to thereby be deformed, so that a space between the opening portion and a sealing member is shut off by the shutoff member when the closure element closes the opening portion. The shutoff member is deformed and continues to contact the second valve seat under normal and high temperature environments when the closure element closes the opening portion.

Abstract: Agate valve apparatus is disclosed. The gate valve apparatus is provided with a valve casing that includes a first valve seat and a second valve seat, and in which an opening portion is formed; and a closure element that includes a sealing member that contacts the first valve seat to seal the opening portion. In addition, the gate valve apparatus is provided with a shutoff member that contacts the second valve seat to thereby be deformed, so that a space between the opening portion and a sealing member is shut off by the shutoff member when the closure element closes the opening portion.

Abstract: A substrate processing apparatus and a thermal processing apparatus are capable of creating a pattern with an excellent line width uniformity. An ACU conditions air to a temperature and a humidity which are suitable to processing which uses a resist of chemical thickening type, while an ammonia removing filter removes an ammonia component from the air and the air is supplied to an air supply pipe which branches off. A pump, a flow meter and a pressure regulator are disposed to an air supply pipe, so that the air from the ACU, as it is conditioned to flow at a constant flow rate and with a pressure, is supplied to a PEB bake unit. Since the temperature and the humidity of an atmosphere within the PEB bake unit stabilize at values which are suitable to processing which uses a resist of chemical thickening type, it is possible to form a pattern with an excellent line width uniformity.
