Abstract
A non-volatile memory cell array having second floating gates with a narrow width, a large height, and slanted side walls. Critical dimension errors due to photolithographic and etching processes are decreased. The difference in the coupling ratio between the memory cells is low thereby improving speed during programming and/or erasing. A second floating gate having a narrower critical dimension than a second floating gate obtained using a photolithographic process may be designed, thereby forming a highly integrated non-volatile memory cell array.
