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.
