Potted Design Rules for SCN3ME and SCN3ME_SUBM


Introduction

SCN3ME: Scalable CMOS N-well, 3 metal, non-silicided, high resistance layer available. Adds a second polysilicon layer (poly2) as the upper electrode of a poly capacitor.

SCN3ME_SUBM: Uses revised layout rules for better fit to sub-micron processes (see MOSIS Scalable CMOS (SCMOS) Design Rules.

Fabricated on AMI 0.50 micron process runs.

Layer Map and Mask Based Rules

Masks required for analogue designs (POLY2, HI_RES_IMPLANT and POLY2_CONTACT) have been omitted from the following list.

Other Rules

In addition to these mask rules, Minimum Density Rules and Process-Induced Damage Rules must be considered.

MOSIS Scalable design rules require that layout is on a 1/2 lambda grid.
