- 11a is a single wafer woofer processing apparatus according to the present invention, which is different from the apparatus shown in FIG. 1 in that a through hole 12, a hollow part 22, a rotary joint 26A, a baffle plate 46, a lower conduit 62, 64, 66, 68, 70 and the main conduit 72 are omitted, and the other configuration is exactly the same as the processing apparatus 11 of FIG.
- the operation is exactly the same as that shown in the flowchart of FIG. 4 except that no chemical solution or the like is supplied from below, and the same explanation is omitted.
- the drying gas for example, nitrogen or air
- the treatment device 11a in Fig. 5 has the inconvenience that it cannot spray dry gas from below.
- the blowing gas may be blown by a blowing means (not shown) other than the nozzle means and this blowing means.
- the chemical solution can be supplied as a raw solution, and management of a compounded chemical solution that does not require circulation heating is not required. Since it is used immediately after that, there is no problem of chemical deterioration, and the maximum effect point of the chemical can be used, enabling the concentration of the chemical to be lower than the conventional concentration of the chemical. be able to.
