Latest Patents
One of McElroy's latest patents is titled "Memory cell array having continuous-strip field-oxide regions." This invention addresses issues related to field oxide corner-rounding in CMOS memory cell arrays. The design incorporates a moat pattern that defines alternating columns of active areas and field oxide regions. Additionally, a source line pattern is utilized to define rows of source lines, with silicon dopant implanted in areas not covered by the source line pattern to create buried n+ source lines. The field oxide regions are formed in areas not covered by the moat pattern, allowing for subsequent fabrication steps to follow conventional CMOS techniques.
Another significant patent is the "MOSFET cell array," which presents a CMOS memory cell array and a process for its fabrication. This invention overcomes challenges associated with LOCOS isolation of cells. The design features moats formed by etching away columns of a thick field oxide layer, with two-tiered sidewalls that provide sloped upper tiers and more vertical lower tiers. This innovative approach offers the benefits of sloped sidewalls while avoiding filament problems, with subsequent fabrication steps adhering to conventional techniques for CMOS arrays.
