A method of manufacturing a nonvolatile memory (NVM) device having a memory gate and a selection gate. A method of manufacturing a NVM device may include a spacer poly formed on and/or over a surface of a substrate including a memory gate. A method of manufacturing a NVM device may include a sacrificing film formed on and/or over a surface of a spacer poly. A method of manufacturing a NVM device may include an etch-back process performed to form a selection gate. The thickness of a memory gate may be minimized. A bridge between a selection gate and a source/drain may be minimized.
