I liked that it was a hands-on experience to work with the material that I had found academically interesting, notable with regards to semiconductor fabrication elements, such as CVD and PVD, and plasma engineering.
What I wish was different
I wish that the lab had been slightly more formal (it is more of a workshop), but this did not hinder any opportunity.
Do not be afraid to ask for help. Even if it's just finding where something is located. You waste time if you think you don't need help but are not sure.
