Abstract
A method of manufacturing a semiconductor device is disclosed. The method forms a semiconductor device including a workpiece structure having a first region and second region located adjacent to the first region formed therein. The first region includes a first pattern and the second region includes a second pattern having at least a greater pattern width or a smaller aspect ratio than the first pattern. The method includes forming the first pattern by providing a first film having a first contact angle at a top portion thereof and the second pattern by providing a second film having a second contact angle less than the first contact angle at a top portion thereof; cleaning the first and the second regions by a chemical liquid; rinsing the cleaned first and the second regions by a rinse liquid; and drying the rinsed first and the second regions.
