For the past few months I have been working in an CM experiment lab at my university (I just wrapped up my first year of undergrad) and am now working for the same professor in an REU over the summer. Though my work, I have come into a lot of contact with nanofabrication techniques (Lithography, chip production, etc) and have become totally fascinated by it. I am beginning to consider this as a career path and am wondering what sort of educational background someone who works on chip development (or any nanofabrication) at, say, Intel or IBM would need. I am currently a Physics major and would like to stay one - for both sheer interest in the topic and a bothersome scholarship that I lose if I change my major. Is this something a physicist would do? I am also open to grad school in other fields (Materials Science? EE?). Any insights are much appreciated.
