Abstract: The present disclosure relates to a self-aligned split gate memory cell, and an associated method. The self-aligned split gate memory cell has cuboid shaped memory gate and select gate covered upper surfaces by some spacers. Thus the memory gate and select gate are protected from silicide. The memory gate and select gate are defined self-aligned by the said spacers. The memory gate and select gate are formed by etching back corresponding conductive materials not covered by the spacers instead of recess processes. Thus the memory gate and select gate have planar upper surfaces and are well defined. The disclosed device and method is also capable of further scaling since photolithography processes are reduced.
