Abstract:
A resist processing apparatus for coating a substrate with a resist, sending the substrate to an aligner and developing the substrate received from the aligner, said resist processing apparatus comprising:a coating unit that coats the substrate with the resist;a developing unit that develops the substrate received from the aligner;an interface unit, through which the substrate is sent to and received from the aligner;a carrier that carries the substrate from said coating unit to the aligner through said interface unit, and to carry the substrate from the aligner to said developing unit through said interface unit;a thermal processing unit that heat-treats the substrate received from the aligner, the substrate being carried by said carrier from the aligner to said thermal processing unit through said interface unit;a buffer unit where a heat-sensing substrate, which is provided with a sensor that measures temperature of said heat-sensing substrate and is configured to be heated in said thermal processing unit, stands by, said buffer unit arranged in said interface unit, such that said heat-sensing substrate is carried to said thermal processing unit by said carrier through a course the same as that of the substrate, so as for said heat-sensing substrate to have a heat history up to said thermal processing unit, the same as that of the substrate; anda reader that reads temperature sensed by said sensor.
