省略する。(Example) A first example of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a cross-sectional view of the main parts of a resist coating device according to the present invention. This embodiment differs from the conventional example shown in FIG. This is the point where the polymer film 6 was formed. Since the rest is the same as the conventional example, the same components are given the same reference numerals and their explanation will be omitted. In addition, a resist 1-
Since the operation of applying the same is also the same as in the conventional example, its explanation will be omitted.

説明を省略する。Next, a second embodiment will be described using FIG. 1 and FIG. 2. The difference between this embodiment and the first embodiment described above is that, instead of the polymer film 6 that easily dissolves in organic solvents, in the first embodiment, a tungsten film that becomes an oxide and dissolves with hydrogen peroxide is used. This is the point where the The resist coating equipment in which the tungsten film was formed is exactly the same as shown in Figure 1, and the operation of the tungsten film is also the same, except that the organic solvent is replaced with hydrogen peroxide.

In addition, since tungsten oxide dissolved in hydrogen peroxide can be easily separated, there is no contamination of wastewater.

Not only does this eliminate manual work, reducing work time, but it also makes the work suitable for work inside a clean room. Further, the time required for peeling is the same regardless of the amount of resist.
