MOSIS Scalable CMOS ([SCMOS]/scn4m_subm)

[SCMOS] is a lambda-based scalable design rules that can be interfaced to many CMOS fabrication process available at MOSIS. NOTE The scalable design rules does not interface with Fabs now because of lot unique process nuances.

• The Spice model files are located at <INSTALL-DIR>/eda-technology/scn4m_subm/models/scn4m_cnrs_bsim3v1.lib
• Typical MOS parameters:
  • NMOS: tox=7.6nm, nch=1.7e17/cm^3, Vt0=0.49V, un(mobility)=445 cm^2/Vs
  • PMOS: tox=7.6nm, nch=1.7e17/cm^3, Vt0=-0.66V, up(mobility)=151 cm^2/Vs
  • Vdd=5V, Lmin=0.4um, Wmin=0.6um

Skywater 130nm PDK
