METHODS OF FABRICATING SEMICONDUCTOR DEVICES HAVING VARIOUS ISOLATION REGIONS
摘要：
A method of fabricating a semiconductor device includes forming a first trench and a second trench in a semiconductor substrate, forming a first insulator to completely fill the first trench, the first insulator covering a bottom surface and lower sidewalls of the second trench and exposing upper sidewalls of the second trench, and forming a second insulator on the first insulator in the second trench.
摘要（中）：

制造半导体器件的方法包括在半导体衬底中形成第一沟槽和第二沟槽，形成第一绝缘体以完全填充第一沟槽，第一绝缘体覆盖第二沟槽的底表面和下侧壁，并暴露上侧壁 并且在所述第二沟槽中的所述第一绝缘体上形成第二绝缘体。
