Abstract
The process includes the following steps. At first, a masking layer is formed over the semiconductor substrate. A portion of the masking layer is then removed to form an opening to the semiconductor substrate. Sidewall spacers are formed on the opening and a portion of the semiconductor substrate is removed to form a trench, through an aperture defined by the sidewall spacers. The sidewall spacers is then removed and a liner layer is formed conformably over the trench.
