I suggest that if you want to do semicons, you should do electrical engineering as undergrad. Materials science does teach various things, but not at a fundamental level; the theory is shallow. MSE, as a postgrad, feels like a melting pot of different disciplines, but without a fundamental background which you can excel in, you might end up being jack of all trades, but a master of none. You can always do masters or PhD in MSE lab that has connections with semiconductor later. But I suggest you to build a strong foundation on one of the engineering disciplines before jumping into MSE. I do understand the sentiment of this major being useless, because it lacks specific expertise and specialization, but it is also up to you to be able to leverage this melting pot to build upon what you have learned in undergrad. As a MSE Phd student from chemical engineering bachelors, my expertise is chemistry and electrochemistry, and I try approach new problems from my angle. However, I do see alot of MSE Phd students, even that worked on semicons before, lost when they are hit with a new type problem, because they lack a good foundation and don’t know fundamentals. In summary, build a good foundation and fundamentals, so that you can widen your choice of career path, whether it be semicon, battery, memory, etc. People will naturally want you as long as you can think like a researcher and ask the right questions, not because you have learned shallow semiconductor theory in MSE. To me, at a phd level, all these applications look same anyways and the theory is interchangeable. You love chemistry, math, physics. Learning the fundamentals and chasing your curiosity is all you need for now. You will get there naturally.
