    摘要: A method for forming a semiconductor device includes forming a first dielectric layer over a first portion of a substrate, forming a charge storage layer over the first dielectric layer and etching a trench in the charge storage layer and the first dielectric layer, where the trench extends to the substrate. The method also includes implanting n-type impurities into the substrate to form an n-type region having a first depth and a first width and implanting p-type impurities into the substrate after implanting the n-type impurities, the p-type impurities forming a p-type region having a second depth and a second width. The method further includes forming a second dielectric layer over the charge storage layer and forming a control gate over the second dielectric layer.
