    • PURPOSE: A method for forming an isolation layer is to improve a planarizing feature in a PECVD(plasma enhanced chemical vapor deposition) in such a manner that an inner wall of a PECVD chamber is coated with an oxide layer or a nitride layer before implementing a plasma treatment, and then implementing the plasma treatment without an in-situ cleaning. CONSTITUTION: The first and second insulating layers are formed on a semiconductor substrate(11). A trench is formed by etching the first and second insulating layers and the semiconductor substrate in a predetermined depth using an isolation mask. A thermal oxide layer is formed on the surface of the trench, and then removed. On the surface of the trench is formed a thermal oxide layer. An insulating layer is deposited on an inner wall of a chamber in which the semiconductor substrate is loaded. The surface of the semiconductor substrate is treated with N2/NH3 plasma. The trench is buried with an O3-TEOS USG(tetraethyl ortho-silicate undoped silicate glass) layer(19).
    • 目的:一种用于形成隔离层的方法是改进PECVD(等离子体增强化学气相沉积)中的平坦化特征,使得PECVD室的内壁在实施之前涂覆有氧化物层或氮化物层 等离子体处理,然后实施等离子体处理,无需原位清洗。 构成:第一和第二绝缘层形成在半导体衬底(11)上。 通过使用隔离掩模,以预定深度蚀刻第一绝缘层和第二绝缘层和半导体衬底来形成沟槽。 在沟槽的表面上形成热氧化层,然后除去。 在沟槽的表面形成热氧化层。 绝缘层沉积在其中加载半导体衬底的室的内壁上。 用N 2 / NH 3等离子体处理半导体衬底的表面。 沟槽用O3-TEOS USG(四乙基原硅酸盐未掺杂的硅酸盐玻璃)层(19)掩埋。
