Abstract:
A method of manufacturing a semiconductor device is provided including providing a semiconductor substrate, forming a first plurality of semiconductor fins in a logic area of the semiconductor substrate, forming a second plurality of semiconductor fins in a memory area of the semiconductor substrate, forming an insulating layer between the fins of the first plurality of semiconductor fins and between the fins of the second plurality of semiconductor fins, forming an electrode layer over the first and second pluralities of semiconductor fins and the insulating layer, forming gates over semiconductor fins of the first plurality of semiconductor fins in the logic area from the gate electrode layer, and forming sense gates and control gates between semiconductor fins of the second plurality of semiconductor fins in the logic area from the gate electrode layer.
