Disclosed is a coating apparatus for applying a resist or developing solution to a semiconductor wafer. This coating apparatus comprises a plurality of nozzles supplied with various resist from a resist source and each adapted to drip the different solution onto the wafer, a vessel in which the nozzles is kept on stand-by, while maintaining the liquids in a predetermined state in the vicinity of discharge port portions of the nozzles, when the nozzles need not be operated, and a nozzle operating mechanism for selecting one of the nozzles kept on stand-by in the vessel, and transporting the selected nozzle to the location of the wafer, whereby the resist is applied to the wafer by means of only the nozzle transported by the nozzle operating mechanism.

A resist process apparatus of the invention serves to load/unload a semiconductor wafer in/from the respective process mechanisms. The apparatus includes a wafer holding member for holding a semiconductor wafer, and X, Y, Z and .theta. driving mechanisms for conveying the wafer holding member to a resist coating mechanism and the like. The wafer holding member includes a support frame which is larger than diameter of a semiconductor wafer, and a plurality of support members, arranged on the support frame, for supporting the semiconductor wafer in partial contact with the peripheral portion of the semiconductor wafer. Since the contact area between the support members and a semiconductor wafer is small, changes in temperature of the semiconductor, when it is held, are small.

An exposure apparatus of this invention is used in an exposure process of semiconductor and LCD devices. The exposure apparatus includes a stage on which a semiconductor wafer is placed, a rotating mechanism for rotating the stage, a radiation unit arranged to oppose a support surface of the stage, a slider mechanism for reciprocating the radiation unit along a straight line passing through the center of the support surface of the stage, an exposure range input unit for inputting a desired exposure range of the wafer, an exposure range memory unit for storing the input exposure range, a CCD image sensor for detecting a reference position of the wafer, a relative position detector for detecting a relative position between the detected reference position and the radiation unit, a controller for controlling the sliding mechanism in correspondence with the relative position and the exposure range, and a light amount control mechanism for controlling an amount of light radiated from the irradiation mechanism to the wafer in correspondence with the relative position and the exposure range.

Just after resist solution is coated on a substrate, it is dried substantially in a non-heating state. In reality, inertia gas or the like is blown from a shower head to the substrate. Thus, the resist solution coated on the substrate is dried. Consequently, transfer marks that cause the film thickness of resist film to be unequal and the line width of a circuit pattern to fluctuate can be prevented.

A washing method for washing objects includes the steps of supplying a washing liquid to a washing vessel and immersing objects in the washing liquid contained in the washing vessel. The method also includes the steps of discharging the liquid at least once from the washing vessel, and starting to apply the washing liquid to the objects when the objects are partly exposed to air as the liquid is discharged from the washing vessel. The washing liquid application is continued during exposure of the objects to the air to prevent the surface of the objects from being dried and stained.

Disclosed herein is a washing apparatus comprising a washing chamber, an opening/closing mechanism, and a nozzle. The chamber has an opening and is designed for washing the objects transported from outside through the opening. The opening/closing mechanism is designed to open and close the opening of the washing chamber. The nozzle is used to wash the opening/closing mechanism. The apparatus further comprises a washing vessel filled with a washing liquid, for washing the objects, and also a nozzle for applying a washing liquid to the objects located in the washing vessel when the objects are partly exposed as the washing liquid is discharged from the washing vessel.
