Abstract
본 발명은 반도체 소자의 금속배선 형성방법에 관한 것으로, 구리박막을 금속배선으로 사용함에 있어, 구리원자의 확사으로 인하여 실리콘 기판의 접합부에서 발생되는 스파이킹형상을 방지하기 위하여 확산방지금속층으로 티타늄-알루미늄-나이트라이드(Ti-Al-N)박막을 형성한 후 열처리에 의해 결정계면 및 표면에 알루미늄산화막이 생성되도록 하므로써 구리박막 형성후의 후속 열처리시 구리원자의 확산이 방지되어 실리콘기판의 접합부에서 발생되는 스파이킹현상이 방지되고, 따라서 소자의 전기적특성이 향상될 수 있도록 한 반도체 소자의 금속배선 형성방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a metal wiring of a semiconductor device. In the case of using a copper thin film as a metal wiring, a titanium-diffusion layer is used as a diffusion preventing metal layer to prevent a spike shape generated at the junction of a silicon substrate due to the expansion of copper atoms. After the aluminum-nitride (Ti-Al-N) thin film is formed, an aluminum oxide film is formed on the crystal interface and the surface by heat treatment to prevent diffusion of copper atoms during subsequent heat treatment after the formation of the copper thin film, thus occurring at the junction of the silicon substrate. The present invention relates to a method for forming a metal wiring of a semiconductor device in which spiking phenomena are prevented and thus the electrical characteristics of the device can be improved.
