Vacuum dryer of drying semiconductor device using the same
A vacuum dryer is obtained by improving the above-mentioned IPA vapor dryer
. In the drying method in which the vacuum dryer is used, the amount of IPA consumed is less than that of the IPA vapor dryer. Therefore, it is possible to reduce the degree of environmental pollution caused by the IPA. Also, it is possible to obtain an excellent drying effect regardless of the presence of the pattern. However, as the semiconductor device is further integrated, recontamination by particles in the drying method in which the vacuum dryer is used comes into question. Therefore, a method of drying a semiconductor device by which it is possible to more stably prevent recontamination by particles is required.
