Filed: 2002-02-05
Granted: 2007-12-21
Abstract: The present invention provides a method for forming a bottle-shaped trench in a semiconductor substrate. Firstly, a hard mask having an opening is formed on a semiconductor substrate. The semiconductor substrate is then etched through the opening of the hard mask to form a trench. The trench is divided into a top part and a bottom part. Secondly, a thin oxide layer is formed on the trench and the surface of hard mask. A blocking material is then filled into the bottom part of the trench, and the thin oxide layer that is not blocked by the blocking material is removed to expose the surface of the semiconductor substrate on the top part of the trench. Thereafter, the blocking material is removed to expose the thin oxide layer on the bottom part of the trench. Then, a thin nitride layer is formed on the surface of the top part of the trench. The thin oxide layer is removed to expose the surface of the semiconductor substrate on the bottom part of the trench. A mixed solution of H2O2 and HF is used as an etchant to etch the semiconductor substrate on the bottom part of trench, thereby forming a bottle-shaped trench. Then, the thin nitride layer is removed.
