Stanford Canonical Design Problem Process Definition Specification By: Edward Chan, Stanford University Date: June 7, 1999 Adaptation of Composite CAD Process Definition Specification v1.0 for 50kHz example found on Composite CAD Extranet. NOTE: Adjusted thicknesses to measurements Removed POLY2 layer from process spec N.B.: Effect of gold (different thicknesses for the same layer) cannot be defined in this spec --------------------------------------------------------------------------- ProcessVersion={ Version=1.0beta } ProcessUnit={ Unit=microns } Wafer={ MaskName="substrate" Thickness=100 Comment="Wafer" } Deposit={ DepositType=CONFORMAL Face=TOP LayerName="Nitride" Thickness=.6 Scf=c Comment="Deposit Nitride" } Deposit={ DepositType=CONFORMAL Face=TOP LayerName="Poly0" Thickness=.53 Scf=0.9 Comment="Deposit Poly0" } Etch={ EtchType=SURFACE Face=TOP MaskName="Poly0" EtchMask=OUTSIDE Depth=0.53 Angle=90 Undercut=0 EtchRemoves="Poly0" Comment="Etch Poly0" } Deposit={ DepositType=CONFORMAL Face=TOP LayerName="Ox1" Thickness=2.16 Scf=.5 Comment="Deposit Ox1" } Etch={ EtchType=SURFACE Face=TOP MaskName="Dimple" EtchMask=INSIDE Depth=.76 Angle=79 Undercut=0 EtchRemoves="Ox1" Comment="Etch Dimple" } Etch={ EtchType=SURFACE WaferID=w1 Face=TOP MaskName="Anchor1" EtchMask=INSIDE Depth=2.16 Angle=79 Undercut=0 EtchRemoves="Ox1" Comment="Etch Anchor1" } Deposit={ DepositType=CONFORMAL Face=TOP LayerName="Poly1" Thickness=1.99 Scf=0.9 Comment="Deposit Poly1" } Etch={ EtchType=SURFACE Face=TOP MaskName="Poly1" EtchMask=OUTSIDE Depth=1.99 Angle=90 Undercut=0 EtchRemoves="Poly1" EtchRemoves="Poly0" Comment="Etch Poly1" } Deposit={ DepositType=SNOWFALL Face=TOP LayerName="Metal" Thickness=.5 } Etch={ EtchType=SURFACE WaferID=w1 Face=TOP MaskName="Metal" EtchMask=OUTSIDE Depth=.52 Angle=90 Undercut=0 EtchRemoves="Metal" Comment="Metal Liftoff" } SacrificialEtch={ EtchType=SACRIFICIAL Face=TOP EtchRemoves="Ox1" EtchRemoves="Ox2" Comment="Sacrificial Etch" }
