Abstract
PURPOSE: To simplify lift-off work by obtaining a pattern section spreading downward, by giving a difference in temperature between the upper layer and lower layer of a resist at te time of developing the exposed resist by using X rays or light.
CONSTITUTION: Resist 2 applied onto substrate 1 is exposed by X rays or light, and ten developed. At this time, the substrate 1 side is heated by hot air 5 from the heater while the resist 2 side is cooled by cool air 6, and developer 4 is supplied onto resist 2. In this way, when the temperature of the resist 2 surface is denoted by T1 and that of the interface between substrate 1 and resist 2 is by T2, temperature difference T2-T1 is set to about 5°C, so that pattern fusion part 3 in an inverted- trapezoid shape can be obtained with slanting angle θ spreading downward nearly equal to 70°. Then, the resist is lifted off after the fixed processes.
