Abstract: Prior to transfer of an wafer W, a mixed gas is being generated and exhausted, thereby fluctuation of concentration and temperature of a solvent component at the beginning of gas introduction into a chamber 3 is suppressed. A step of gelling after the wafer W is carried into an aging unit is divided into several steps. Until a temperature of the wafer W reaches a predetermined treatment temperature, an average concentration of the solvent component in a mixed gas is gradually raised relative to the temperature of the wafer W. Thereby, immediately after the wafer W is transferred into a sealed chamber, the gas of the solvent component is prevented from condensing.

Abstract: When a substrate coated with a coating solution which oxidizes at high temperatures is heat-treated, an oxygen concentration of a treatment atmosphere is lowered when the temperature is low. Next, the substrate is heat-treated in the treatment atmosphere of which the oxygen concentration is lowered. Sequentially, the treatment atmosphere is returned to that with the original oxygen concentration after the passage of a predetermined time after completing the heat treatment. Thereby, the substrate can be heat-treated, with the oxidization of the coating solution being controlled.

Abstract: After a first processing solution is spread over the front surface of a substrate and the temperature of the front surface of the substrate is regulated at a predetermined substrate temperature, a second processing solution is spread over the front surface of the substrate. The second processing solution can be spread while the front surface temperature of the substrate is maintained at the predetermined substrate temperature. Hence, a layer insulating film with good adhesion properties can be formed uniformly on the front surface of the substrate, and the quantity of the processing solution to be used can be reduced.

Abstract: A gas flow regulating surface portion 37a is the farthest from the front surface of a wafer W in the middle between a peripheral portion of the wafer W and a center portion of a sealing vessel. The gas flow regulating portion 37a protrudes to the front surface of the wafer W in the vicinity of a center portion that surrounds an exhausting opening 35a. In other words, a convex portion 37c is formed in a peripheral area of the gas flow regulating surface portion 37a that surrounds the exhausting opening 35a. Since treatment gas flows along the front surface of the gas flow regulating portion 37a, treatment gas equally contacts the wafer W in the radius direction of the wafer W. Thus, a film with equal thickness is formed.

Abstract: Both of a first insulating film and a second insulating film are formed by a spin coating method. Accordingly, the formation of the first insulating film and the second insulating film can be performed in the same SOD processing system. Moreover, the aforesaid formation of both of the first insulating film and the second insulating film by the spin coating method can provide favorable low dielectric constant properties and good adhesion of the first insulating film and the second insulating film.

Abstract: Processing of applying ultraviolet rays to a front face of an insulating film material formed on a wafer W is performed, whereby a contact angle of the front face thereof becomes smaller. Accordingly, when an insulating film material is applied on the aforesaid front face, the material smoothly spreads, and projections and depressions never occur on a front face of an upper layer insulating film material. Thereby, it is possible to form the insulating film thick and flatter on a substrate.

Abstract: In a hot plate for performing heat processing while an inert gas is supplied, a mounting table is provided with a groove and a lower end portion of a lid body can be inserted into the groove. The lid body is lowered in two steps by a lid body drive apparatus. The lid body forms a processing chamber between the lid body and the mounting table by the lowering of the first step, and the lower end portion of the lid body is inserted into the groove by the lowering of the second step, thereby reducing the processing chamber in capacity. Consequently, in a substrate processing apparatus which requires a supply of gas, it becomes possible to reduce the capacity of the processing chamber and to reduce the required amount of gas.
