Abstract: A semiconductor device manufacturing method includes preparing a wafer having projections formed on a substrate. The projections project upward from a surface of the substrate and have a height measured from the surface of the substrate. The method further includes determining an interval distribution representing a distribution of intervals between neighboring projections and calculating an implantation angle based on the height and the interval distribution. The implantation angle is an angle between a normal direction of the substrate and an implantation direction. The method also includes implanting ions at the calculated implantation angle.

Abstract: A non-volatile memory structure includes a source and a drain. The memory structure includes a substrate and a dielectric layer on the substrate. The memory structure further has a gate, which can be a floating gate, on the dielectric layer. A recess is on the drain side and nearest to the bottom corner of the dielectric layer. The recess is configured to reduce the electric field density around the bottom corner nearest to the drain in order to reduce the damage on the dielectric layer when the memory is under a bias.
