Abstract

본 발명은 반도체 소자의 트랜지스터 제조방법이 개시된다.The present invention discloses a transistor manufacturing method of a semiconductor device.

본 발명은 게이트 전극 마스크 작업으로 폴리실리콘층을 1차 식각하고, 1차 식각으로 형성된 식각면에 스페이서를 형성한 후 2차 식각하여 게이트 전극을 완성하고, 소오스/드레인 불순물 주입 공정을 실시하여 LDD구조의 트랜지스터가 제조된다.According to the present invention, a polysilicon layer is firstly etched by a gate electrode mask operation, a spacer is formed on an etch surface formed by the first etch, and then secondly is etched to complete a gate electrode, and a source / drain impurity implantation process is performed to perform LDD. A transistor of the structure is manufactured.

따라서, 본 발명은 한번의 소오스/드레인 불순물 주입공정으로 소오스/드레인 영역과 LDD영역을 동시에 형성시켜 LDD구조의 트랜지스터를 제조하므로 공정을 단순화 할 수 있으며, 특히 LDD 영역이 폴리실리콘으로 완전히 덮혀지게 되므로서 게이트 전압으로 용이하게 조절 가능하여 핫 캐리어에 의한 소자의 신뢰성 저하방지 및 전류 구동 능력을 향상시킬 수 있다.Therefore, the present invention can simplify the process by forming a transistor having an LDD structure by simultaneously forming a source / drain region and an LDD region in a single source / drain impurity implantation process, in particular, since the LDD region is completely covered with polysilicon. It can be easily adjusted by the gate voltage to prevent the device from being degraded by hot carriers and improve the current driving capability.
