。FIG. 1 of the accompanying drawings is a sectional view of one configuration example of a conventional device. In addition, in the following description of the drawings, the same elements are indicated by the same reference numerals. A wafer chuck 3 that attracts and holds a wafer 2 by vacuum is attached to the tip of a spindle 1 that is rotated by a drive mechanism (not shown). A nozzle 4 for dropping a chemical solution is provided above the wafer 2, and the sides and bottom of the wafer 2 are surrounded by a cup 5. Discharge ports 6a and 6b are provided on the lower side of the cup "5" for discharging medicinal liquid and the like.

。Next, the operation of the configuration example shown in FIGS. 1 and 2 will be explained. When applying resist with this configuration example, first drop 1" of resist from the nozzle 4 onto the center of the wafer 2 in a stationary state. Next, rotate the wafer 2 at a low speed (it is not necessary to rotate it). ) Diffuse resist onto the surface of the wafer 20 and form a uniform resist film at a predetermined rotation speed.

することはできない。However, according to the technique shown in Japanese Patent Application Laid-Open No. 54-9919, although it is effective in preventing re-adhesion due to the splashing of the chemical liquid from the cup 5, it is effective in preventing the chemical liquid from being splashed onto the back surface of the wedge 2. cannot be effectively prevented. On the other hand, according to the technique disclosed in Japanese Patent Application Laid-Open No. 55-165170, although it is possible to prevent the chemical liquid from being spilled onto the back surface of the wafer 2, it is not possible to effectively prevent the chemical liquid from being reprinted due to splashing of the chemical liquid from the cup 5. I can't.

Non-uniformity appears in the fluid flow near the wafer, which causes non-uniform chemical temperature (a temperature difference appears between the center and the periphery of the wafer), and the vapor pressure of the chemical (for example, resist solvent) Situations such as unevenness may occur. This unrestricted fluid flow causes non-uniform resist film thickness and non-uniform development, resulting in a decrease in the accuracy of pattern dimensions of semiconductor elements.
