    Abstract: PROBLEM TO BE SOLVED: To provide a method for composing and forming an insulation structure for a semiconductor device.
    SOLUTION: The insulation structure is more widened at the bottom than at the top, so that the size of the semiconductor device can be adjusted. A first etching process is used to form a first trench 226, and a second etching process or an oxidation process is used to form a second trench 228 under the first trench 226. The second trench is wider than the first trench. In one embodiment, a base film 222 may be formed between the first trenches, and on the side wall of the first trench (the first trench protects the side wall of the first trench during the second etching process). Alternatively, the base film 222 may be deposited on the side wall of the first trench in another embodiment.

    解决方案:绝缘结构在底部比顶部更宽,从而可以调节半导体器件的尺寸。 使用第一蚀刻工艺来形成第一沟槽226,并且使用第二蚀刻工艺或氧化工艺在第一沟槽226下方形成第二沟槽22.第二沟槽比第一沟槽宽。 在一个实施例中,可以在第一沟槽之间和第一沟槽的侧壁(第一沟槽在第二蚀刻工艺期间保护第一沟槽的侧壁)形成基膜222。 或者,在另一个实施例中,基膜222可以沉积在第一沟槽的侧壁上。 版权所有(C)2011,JPO&INPIT
