Hi Garth,

Laser Direct Imaging (LDI) is a term that has been applied to exposing a
photo resist directly with a laser beam - no phototool used.  Etec and
Orbotech both have imagers that can do this.  I understand CREO also showed
a new imager of this type.

I'm not familiar with the Direct Laser Writing, but I don't get very close
to MCM applications.
