Title: Method of forming a mask pattern in a semiconductor device
Inventor: CHOI JAE SEONG
IPC: H01L21/027
Filed: 2002-12-20
Abstract: PURPOSE: A method for forming a mask pattern of a semiconductor device is provided to lower fabricating cost and improve integration of a device by making a mask pattern finer than a resolution of exposure and development equipment such that the mask pattern has etch tolerance or an ion injection intercepting characteristic. CONSTITUTION: A photoresist pattern(102) having a pattern finer than the resolution of the exposure and development equipment is formed on a semiconductor substrate(101) by using resist that has a better exposure and development characteristic than etch tolerance. An intermixing blocking layer(103) is formed on the photoresist pattern. A polymer compound(104) having a better ion injection intercepting characteristic than a development characteristic is formed on the resultant structure including the photoresist pattern. A CMP(chemical mechanical polishing) process is performed until the upper surface of the photoresist pattern is exposed. The photoresist pattern and the intermixing blocking layer are eliminated to form a mask pattern(104a) finer than the resolution of the exposure and development equipment such that the mask pattern is made of a polymer compound having an ion injection intercepting characteristic.
