spice models for MOSFET deplation

[Mostafa.A]

I need spice models, for nMOS & pMos transistor. for example: "TSMC 0.25um spice module."
who know where can I found this model?

I found below link for spice models of MOS transistor.
https://www.mosis.com/pages/Technical/Testdata/index

but all of them be for enhancement MOS. because their models, have positive Vth(threshold Voltage) for nmos.

depletion model's Vth (for nmos), should be negative

I don't think that depletion mode MOSFETs are avaible in TSMC 0.25um or similar standard processes. It's easy to change Vth for simulation purposes, but not reasonable if you are designing a manufacturable chip.
