  • Patent number: 10325956
    Abstract: Some embodiments of the present disclosure relate to a method in which a functional layer is formed over an upper semiconductor surface of a semiconductor substrate, and a capping layer is formed over the functional layer. A first etchant is used to form a recess through the capping layer and through the functional layer. The recess has a first depth and exposes a portion of the semiconductor substrate there through. A protective layer is formed along a lower surface and inner sidewalls of the recess. A second etchant is used to remove the protective layer from the lower surface of the recess and to extend the recess below the upper semiconductor surface to a second depth to form a deep trench. To prevent etching of the functional layer, the protective layer remains in place along the inner sidewalls of the recess while the second etchant is used.
