how to fabricate SOI MOSFET macro model ?

[spice3]

The parameters of SOI NMOSFET I extracted can't simulate kink effect. The
real device is body tied. But it still has kink effect. so I want to
fabricate a macro model. I used a MOSFET and a BJT transistor. The
parasitical capacitor will be taken into account through the parameters of
MOSFET. But how to simulate the floating body? By default the voltage of
base electrode is zero if no bias added. Then the kink effect caused by Vt
enhancement still can't be simulated. How should I do ? Thanks!

Have you considered simpy purchasing a few SOITEK wafers and trying
it? Some things are difficult to emulate on a computer simulation, and
I suspect that this is still another of one of them.
