Hi, I am an undergraduate student in Hong Kong. I am doing a research on laser micromachining. Would you mind to answer some questions for me please? Thanks. 1. What is the minimum feature size that can be produced by laser micromachining in IC fabrication? 2. How "micro" do you expect laser micromachining can do in the future? 3. How costly is laser micromachining compared with other micromachining process? Thanks a lot
