  • Patent number: 9748255
    Abstract: Some embodiments of the present disclosure relate to a memory device, which includes a floating gate formed over a channel region of a substrate, and a control gate formed over the floating gate. First and second spacers are formed along sidewalls of the control gate, and extend over outer edges of the floating gate to form a non-uniform overhang, which can induce a wide distribution of erase speeds of the memory device. To improve the erase speed distribution, an etching process is performed on the first and second spacers prior to erase gate formation. The etching process removes the overhang of the first and second spacers at an interface between a bottom region of the first and second spacers and a top region of the floating gate to form a planar surface at the interface, and improves the erase speed distribution of the memory device.

  • Publication number: 20170243915
    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.
