*LINE1: [ GRAD ] line on [ Y1 ] at a point where
[ VG ] = [ 5 ]
[ ]
Gradient: [ 0 ]
-----------------------------------------------------------
*LINE2: [ NORMAL ] line on [ Y1 ] at a point where
[ ID ] = [ 10u ]
[ ]
and a point [WHERE]
[ ID ] = [ 10u ]

*Interpolate: [ON ]
PARAM.MES setup file extracts Idlin and Vtci by using the 4155/4156 User
Function and Auto Analysis Function. These parameters are extracted with the
following conditions:
Idlin: Gate voltage VG=5 V
Substrate voltage VB=0V
Vtci: W/L Ratio (Gate width/Gate length ratio) =10
μ
m/1
μ
m
For changing the conditions, refer to “Modifying the Program” on page 9-35.
