Abstract
금속 게이트 전극을 갖는 트랜지스터 및 그 제조 방법.이 개시되어 있다 본 발명은 트랜지스터를 형성함에 있어서, 게이트 전극의 상부 금속막 패턴으로 비저항이 매우 작은 금속을 선택적으로 증착하여 게이트 전극의 저항을 낮추고, 하부 금속막 패턴으로는 질화계금속막을 형성하여 표면 채널을 갖는 P채널 트랜지스터를 제조하는 것이다.A transistor having a metal gate electrode and a method of manufacturing the same are disclosed. According to the present invention, in forming a transistor, a metal having a very low resistivity is selectively deposited on the upper metal film pattern of the gate electrode to lower the resistance of the gate electrode, and The metal film pattern is to form a nitride metal film to produce a P-channel transistor having a surface channel.
