The printed circuit board industry uses stencils cut by lasers from thin stainless steel. (They use them for applying solder to PCB boards). The minimum hole size is about .001", I think, with the stencil thickness also on the same order of thickness. They should be available for about $300. Goto to Google and search on "Laser Cut Stencil", and a bunch of companies should pop up.

Please note that I will be using the shadow masks to fabricate thin film resistors and thermocouples on a substrate using e-beam evaporation. Thank you.
