ULTRA SMALL THIN WINDOWS IN FLOATING GATE TRANSISTORS DEFINED BY LOST NITRIDE SPACERS |
| 摘要 |
A tiny oxide window, the upper layers (55, 57) are etched leaving the poly-two layer (57) over the laywe (41). The optional nitride spacers (51, 53) remain as protective barriers for the poly-one layer and its underlying oxyde layer. Source and implants (22, 24) may be made using the ONO layer as a self-alignment tool.
