    A structure of nonvolatile memory is formed by a substrate, a stack grid structure and a source/drain region. The stack grid is on the substrate. The source/drain region in the substrate at the both sides of the stack grid. A vertical stepped channel dosed contour is formed in the substrate. It is devided into the first dosed region below the surface of the substrate and the second dosed region adjacent the first one. The concentration of the second one is higher than that of the first one.
