Unfortunately, the standard set of 0.18 tech files (SCN6M_DEEP.09.tech27,
and variants) do not have any high-voltage devices.  Normally these
would appear in the techfile as layers with "hv" prepended (hvntransistor,
hvndiffusion, etc.).  They appear in a number of the larger-feature-size
technology files.

It is possible to get a technology file for TSMC 0.18 with high-voltage
devices (and intrinsic devices) because I am working on one right now.
However, I have to finish it up, document it, and pass it on to Wes
Hansford at MOSIS so it can be made available for download from their
secure document server.  The slowest part of this process so far has
been me getting around to writing the documentation.

I have not seen any 0.13 technology files for magic at this point.
At one time I was prepared to create one for the Chartered Semiconductor
process, but we have sort of passed that opportunity by and will probably
go to TSMC 90nm when it comes time to design and test something smaller
than 0.18.
