Title: Method for forming self-align contact hole of semiconductor device and gate electrode thereby
Inventor: CHO HYE JIN
IPC: H01L21/28
Filed: 2001-11-06
Abstract: PURPOSE: A method for forming a self-alignment contact hole of a semiconductor device is provided to prevent a bit line from being contacted with conductive material by conserving the original thickness of a nitride silicon layer. CONSTITUTION: After sequentially forming a conductive layer and the first isolating layer made of a nitride silicon layer on a semiconductor substrate(30), a photoresist layer pattern is formed on the resultant structure. An isolating layer pattern(40) is formed by etching the first isolating layer using the photoresist pattern as a mask. At this time, the conductive layer is partially etched at the range of 40-60%. After removing the photoresist layer pattern, a conductive layer pattern made of a titanium nitride layer pattern(42) and a tungsten layer pattern(44), is formed by etching the conductive layer using the isolating layer pattern(40) as a mask. At this time, the original thickness of the isolating layer pattern(40) is conserved because of the pre-etching of the conductive layer. After an insulating spacer(46) is formed at both sidewalls of the isolating and conductive layer pattern, the second isolating layer(48) is formed on the entire surface of the resultant structure. A self-alignment contact hole(50) is formed in the resultant structure for exposing the isolating layer pattern(40).
