    Abstract: An apparatus for and a method of heat-treating a wafer for use in producing a semiconductor device ensures a desired distribution of surface temperatures across the wafer. Spacers are used to space the wafer above a heat transfer plate. The spacers can be used to adjust the spacing and inclination of the wafer relative to the heat transfer plate by predetermined amounts determined in advance to produce the desired distribution of surface temperatures across the wafer during heat-treatment. With the present invention, wafers can be heat-treated during production using a plurality of bake units disposed in parallel because each of the bake units can be precisely adjusted using the spacers to produce surface temperature distributions similar to a standard surface temperature distribution. Accordingly, the productivity of the semiconductor manufacturing process can be markedly enhanced.

    Abstract: A method and apparatus for uniformly spin-coating photoresist material on wafers before the wafers are subjected to a photoetching process. The spin-coating apparatus comprises a first rotating device for rotating a rotating connector about a first axis and a second rotating device located on the outer portion of the rotating connector. The second rotating device rotates a wafer about a second axis while the rotating connector rotates around the first axis. The first and second axes are parallel to each other but are spaced apart by a designated distance. The designated distance can be adjusted and a plurality of second rotating devices may be connected to outer portions of the rotating connector.
