Abstract:
1. A nonvolatile memory cell comprising: a semiconductor substrate; first and second memory cells on the semiconductor substrate and separated by a distance; a first source and a second source in the semiconductor substrate adjacent the first and second memory cells; a drain in the semiconductor substrate between the first and second memory cells; first and second cap dielectrics on top surfaces of the first and second memory cells, respectively; first and second sidewall spacers on sidewalls of the first and second memory cells, respectively; a dielectric layer in direct physical contact with the first and second cap dielectrics and the first and second sidewall spacers on opposite sidewalls of the first and second memory cells, the dielectric layer defining a drain contact hole exposing the drain and the first and second sidewall spacers on one of the opposite sidewalls of each of the first and second memory cells; and a drain contact connected to the drain through the drain contact hole.
