Light speed is defined as photons moving in a vacuum. Anything else, which definitely includes electrons in a semiconductor, is slower.

You need to actually switch a transistor or two on the way to+fro (otherwise there would be no point in the exercise ;-), which requires moving a charge, which requires yet more time.
