    摘要: A method of making a semiconductor device on a semiconductor layer includes forming a gate dielectric and a first layer of gate material over the gate dielectric. The first layer is etched to remove a portion of the first layer of gate material over a first portion of the semiconductor layer and to leave a select gate portion. A storage layer is formed over the select gate portion and over the first portion of the semiconductor layer. A second layer of gate material is formed over the storage layer. The second layer of gate material is etched to remove a first portion of the second layer of gate material over a first portion of the select gate portion. A portion of the first portion of the select gate is etched out to leave an L-shaped select structure. The result is a memory cell with an L-shaped select gate.

    摘要: Split-gate non-volatile memory (NVM) cells having select-gate sidewall metal silicide regions are disclosed along with related manufacturing methods. Spacer etch processing steps are used to expose sidewall portions of select gates. Metal silicide regions are then formed within these sidewall portions of the select gates. Further, metal silicide regions can also be formed in top portions of the select gates. Further, the select gates can also be formed with one or more notches. By expanding the size of the metal silicide region to include the sidewall portion of the select gate, the select gate wordline (e.g., polysilicon) resistance is reduced for split-gate NVM arrays, the electrical contact to the select gate is improved, and performance of the select-gate NVN cell is improved.
