SCN4ME and SCN4ME_SUBM
MOSIS SCMOS Technology Codes and Layer Maps
This is the layer map for the technology codes SCN4ME and SCN4ME_SUBM using the MOSIS Scalable CMOS layout rules (SCMOS) and only for SCN4ME and SCN4ME_SUBM. For designs that are laid out using other design rules (or technology codes), use the standard layer mapping conventions of that design rule set. For submissions in GDS format, the datatype is "0" (zero) unless specified in the map below.
SCN4ME: Scalable CMOS N-well, 4 metal, 2 poly, polycide, no silicide block, thick oxide option available.
SCN4ME_SUBM: Uses revised layout rules for better fit to sub-micron processes (see MOSIS Scalable CMOS (SCMOS) Design Rules, Section 2.4)
TSMC 0.35 micron process runs.
