This may depend on the university, but materials science is the best major for the semiconductor industry. It''s not even close. You don''t even strictly need a PhD, if you''re coming from a good school, with a decent semicon focus in core curriculum, and good technical elective options. Grad degrees always help though.
I am an Australian materials engineer, and I got my graduate job this year. I also have a mechanical major, but didn''t get anywhere with applying for jobs on that basis (which is good, since I enjoy materials a lot more). Yes there aren''t as many jobs as the big 4 disciplines, but there also aren''t as many applicants.
