HCI Measurement Program

To change the 4155/4156 setup file used

To change the 4155/4156's setup file used for the HCI test program, modify the setting of the setup file and save it as a new setup file. Then change the following parameter in the "Definition of measurement and stress setup files" block of the program.

Parameter

Description

Default

 

 

 

Ibvg_file$

Setup file for extracting Vgstr.

"IBVG.MES"

 

 

 

Igleak_file$

Setup file for Gate leakage current

"IGLEAK.MES"

 

measurement.

 

 

 

 

Idleak_file$

Setup file for Drain leakage current

"IDLEAK.MES"

 

measurement.

 

 

 

 

Param_file$

Setup file for parameter measurement.

"PARAM.MES"

 

 

 

To change Vtci extraction condition

To change W/L ratio (Gate width/Gate length ratio) required for Vtci extraction, do follows.

1.GET the PARAM.MES setup file by using the 4155/4156.

2.Change the setting of "ID" parameter in "LINE2" on the ANALYSIS SETUP screen. The value of "ID" can be calculated by the following expression.

ID=1 μA W/L

where, W means Gate width in m, and L means Gate length in m.

3. Change the following parameters in the "Device geometries" block of program.

Parameter

Description

Default

 

 

 

Gate_length

Gate length in m.

1.E-6

 

 

 

Gate_width

Gate width in m.

1.E-5
