ABSTRACT:
The present invention relates to a method of forming a photosensitive film pattern. It provides a method of forming a photosensitive film pattern capable of performing a photolithography process by blocking an opening of a high aspect ratio trench with a DFR film, during forming a semiconductor element and an MEMS element. In addition, it is possible to prevent the photoresist from flowing into the trench when the liquid photoresist is deposited by a spin coating method to form the photosensitive film pattern for metal pattern to apply electric signal from outside to inside of trench.
