I don't think it's possible, but I don't have any data one way or the other. of course, silicon wafers are etched using ultraviolet lithography, and have very very fine traces, so it is possible, but I'm sure they use some pretty high end hardware. half a mil? that’s pretty damn small. most of your big time board houses usually draw the line at 3-5 mil.
