3. VLSI/ULSI Process Technology

I plan to pursue an MS after my engineering(at least that's the plan, though I might decide that MBA is a better option, later). Considering that I might go in for MS later, and also considering placements, what subject would be the most useful for me? I need to decide by tomorrow, so please help.
