Memory array with sub-minimum feature size word line spacing and method of fabrication

摘要

A non-volatile memory array (30) has word lines (32) spaced a sub-F (sub-minimum feature size F) width apart and bit lines generally perpendicular to the word lines. The present invention also includes a method for word-line patterning of a non-volatile memory array which includes generating sub-F word lines from mask generated elements with widths of at least a minimum feature size F.
