    • 본 발명은 트렌치 식각 마스크(trench etch mask) 형성 및 제거 공정에 의한 소자의 특성 열화를 방지하는 트렌치 격리의 제조 방법에 관한 것으로, 폴리실리콘막 및 반사 방지막 또는 폴리실리콘막 및 실리콘 질화막이 차례로 적층된 막을 트렌치 식각 마스크로 사용하여 반도체 기판이 식각 되어 트렌치가 형성된다. 트렌치 내벽 및 폴리실리콘막의 측벽에 열산화막이 형성된 후, 열산화막 및 트렌치 식각 마스크 상에 질화막 라이너가 형성된다. 트렌치가 트렌치 격리막으로 완전히 채워진 후, 트렌치 식각 마스크의 상부 표면이 노출될 때까지 트렌치 격리막이 평탄화 식각 된다. 트렌치 식각 마스크가 건식 식각 내지 습식 식각 공정으로 제거된다. 패드 산화막 및 돌출된 열산화막, 그리고 돌출된 질화막 라이너가 제거되어 트렌치 격리가 완성된다. 이와 같은 반도체 장치의 제조 방법에 의해서, 패드 산화막 상에 실리콘 질화막 대신 폴리실리콘막이 형성되므로 반도체 기판에 가해지는 스트레스(stress)를 줄일 수 있고, 실리콘 질화막 인산 스트립 공정에 의해 트렌치 격리의 에지(edge) 부위에 발생되는 덴트를 방지할 수 있으며, 따라서 소자의 특성 열화를 방지할 수 있다. 또한, 실리콘 질화막 라이너를 원하는 두께로 증가시킬 수 있고, 따라서 소자의 신뢰도를 증가시킬 수 있다.

    • PURPOSE: The method can remove a dent generated around the edge of a trench isolation(120), and can prevent a gate bridge. CONSTITUTION: A trench(106) is formed by etching a semiconductor substrate(100) using a nitride mask. A SiN liner(110) is formed on the nitride mask including an oxide after the oxide is formed on the bottom and on both side walls of the trench. A trench isolation film(112) is formed on the SiN liner until the trench is filled completely. The trench isolation film and the SiN liner is planarized by etching until the upper surface of the nitride mask is revealed. After the nitride mask is striped, a sacrificial oxide is formed on the front surface of the semiconductor substrate. After the sacrificial oxide is striped, the SiN liner remained around the dent is etched. The dent around the edge of the trench isolation is removed by making the upper surface of an active equal to the depth of the dent by applying the sacrificial oxide formation process after the nitride mask strip process, and the gate bridge generated because a poly remains behind around the dent during a gate poly formation.
    • 目的:该方法可以消除沟槽隔离边缘周围产生的凹陷(120),并可以防止栅极桥。 构成:使用氮化物掩模蚀刻半导体衬底(100)形成沟槽(106)。 在沟槽的底部和两个侧壁上形成氧化物之后,在包括氧化物的氮化物掩模上形成SiN衬垫(110)。 在SiN衬垫上形成沟槽隔离膜(112),直到沟槽被完全填充。 通过蚀刻将沟槽隔离膜和SiN衬垫平坦化,直到显露出氮化物掩模的上表面。 在氮化物掩模条纹化之后,在半导体衬底的前表面上形成牺牲氧化物。 在牺牲氧化物被条纹化之后,保留在凹陷周围的SiN衬垫被蚀刻。 通过在氮化物掩模剥离处理之后施加牺牲氧化物形成工艺使得活性物体的上表面等于凹坑的深度来消除沟槽隔离边缘处的凹陷,并且由于聚合物留下后产生的栅极桥 在门多晶形成期间围绕凹陷。

    • PURPOSE: The method can prevent the dent generation around the edge of a trench isolation(112), and can improve the electrical characteristics of the trench isolation. CONSTITUTION: After a trench(106) is formed, a SiN of a trench etch mask is stripped. A SiN liner(110) to prevent a thermal oxide(108) on the inner wall of the trench and the oxidation of the inner wall of the trench is formed in sequence. After the trench isolation is deposited, the trench isolation is planarized and etched until the top surface of the SiN liner is revealed. A pad oxide is removed after the SiN liner on both sides of the trench is stripped. The method can prevent the dent generated around the edge of the trench isolation because the SiN liner is over-etched when the SiN is stripped, and can prevent a gate bridge generated because a poly remains behind around the dent when forming a gate poly.
    • 目的:该方法可以防止沟槽隔离边缘周围的凹陷(112),并可以改善沟槽隔离的电气特性。 构成:在形成沟槽(106)之后,剥离沟槽蚀刻掩模的SiN。 依次形成用于防止沟槽内壁上的热氧化物(108)和沟槽内壁的氧化的SiN衬垫(110)。 在沉积沟槽隔离之后,沟槽隔离被平坦化并蚀刻直到SiN衬里的顶表面露出。 剥离沟槽两侧的SiN衬垫之后去除衬垫氧化物。 该方法可以防止在沟槽隔离边缘周围产生的凹陷,因为当SiN被剥离时,SiN衬垫被过度蚀刻,并且可以防止由于在形成栅极聚合物时残留在凹陷周围的聚合物而产生的栅极桥。
