Hicum
Why ?
There’s a need for companies in this domain:
•
Help to accelerate the FIRST use of Hicum
and help to establish a wide use
•
Provide complete extraction services for
companies having no experience in the bipolar
domain (SiGe and III-V HBT’s)
•
Provide consulting for modelling of very High
frequency devices, need of scaling, ...
Centralise Bipolar experience

Goals of the “Hicum Aperitif Toolkit”
?
Gummel-Poon
Switch
 Learn a new model and new tools
 Scaling approach can be complex
 New test structures on the wafers

Goals of the “Hicum Aperitif Toolkit”
Gummel-Poon
Hicum
Switch
“Hicum Aperitif Toolkit” allows to use the single
transistor strategy (SGP like)
Simplified approach
Decouple Scaling from parameter extraction
No specific test structures
HICUM Workshop, September 2002, Monterey
Goals of the “Hicum Aperitif Toolkit”
“Hicum Aperitif Toolkit” allows to:
Evaluate the model without too much effort
A smooth transition from SGP to Hicum
Obtain efficient and physically
meaningful parameter sets for Hicum
(from direct extraction)
Parameters extracted for the
single transistor approach will be required
for scaling (Transit time)
