Both really since the technology relies on the science. We would hardly have the first transistors without the theory behind these.
We don't really understand how transistors work. We know how to make them and are continually finding ways to make them smaller but why some materials conduct electricity better than others is one of those things we discover through trial and error rather than understanding.
In the old days when it was necessary to use matched transistors in stereo equipment. Even though you had an entire crate of transistors made "exactly" the same they'd each have a unique power output and it was necessary to select two similar ones to build equipment. Then there were variable pots to adjust the two transistors to the specific unit. Each piece of equipment that came off the assembly line was different. They're still different but getting the right sound is far less labor intensive.
