Title: A fine pattern for semiconductor forming method
Inventor: LEE IL HO
IPC: G03F7/00
Filed: 1993-12-21
Granted: 2000-06-01
Abstract: PURPOSE: A method for forming the micropattern of semiconductor device is provided, to prevent the proximity effect, the necking and the generation of bridge, thereby to improve the resolution of micropattern and the stability of process. CONSTITUTION: The method comprises the steps of forming a conductive layer(1) on the semiconductor substrate(10) by evaporation-deposition, and coating a lower photosensitive layer(2), an intermediate layer(3) and an upper photosensitive layer(4) on the conductive layer(1); exposing the upper photosensitive layer(4) by using a photo mask(6), developing the upper photosensitive layer(4) to form an upper photosensitive layer pattern(4'), and forming an intermediate layer pattern(4') by using the upper layer(4) as a mask; exposing the lower photosensitive layer(2) by using an undiffracted light by using the intermediate pattern(3') as a mask and developing the lower layer(2) to form the lower photosensitive layer pattern(2'); etching the conductive layer(1) by using the intermediate layer pattern(3') and the lower layer pattern(2') as a mask, to form the conductive layer pattern(1'); and removing the lower layer pattern(2') and the intermediate layer pattern(3') by wet method.
