Winter 2022 - Emaminejad is a good professor. His lectures are clear and the slides are very helpful. The tests were pretty difficult but looked similar to lecture. It's just too bad that semiconductors is a field invented by satan to torment EE students. Nothing about the field is intuitive. There are a bunch of random formulas/graphs and weird chemistry/physics. This class is very similar to ECE 2, so know that it is more of the same. I thought that this course would give me more of an insight and understanding, but I am still confused. Many things from ECE 2 were cleared up but a lot of the new material added to my confusion. I studied it the best I could and did pretty well in the course, but I feel like there is much more for me to learn if I wanted to work in fabrication. This is a core course and I would recommend taking it with Emaminejad. Other core courses I would recommend are 141 and 101B. There are some much worse core courses and professors that are more worth your two skips.

Fall 2018 - This class was very difficult. The professor himself said this wasnlike the honors 121b but without the honors credit lol. No one showed up to lecture but I did as did 15-20 people out of 75. The material is very hard. EE 2 is not enough prep tbh. Averages are low and the midterm was 20 pages and the final was a whopping 39 pages long. Did not finish both exams. In fact i left 1/4 of the midterm and final blank. You need to read the book and do a lot of outside practice because lectures have 0 examples. It’s only theory. The professor is a nice guy and very smart. Just way smarter than the average student. Homework load was heavy. 9 homework’s total for the quarter. And the equations needed to solve aren’t in the slides or the book so you gotta do a lot of assuming and derivations your self. Grading is ok as it is curve dependent in the end.

Actually kinda got me interested in solid state stuff once we hit MOS capacitors and MOSFETS. Lectures with a tablet - powerpoint with annotations. He definitely tries to make sure everyone understands the material, and he emphasizes the crucial points. He will answer all questions in class. One of the best EE professors.
