This is for HP's CMOS26B 1.0 micron CMOS Bulk Process.
|
|
All parameters are defined based on HP's general process
|
|
specifications (GPP). Sidewall fringing was taken from
|
|
Ersatco fictitious process (johnson,jouppi).
|
|
|
|
Upwards fringe caps (eg poly-->m1, poly-->m2) are computed
|
|
by the program scaleCap by using the Skurai/Tamaru formula
|
|
based on the known capacitances.
