Fulton Schools Professor Trevor Thornton, an electrical engineer who studies semiconductors, provides basic information on what they are, how they are made, what they do and how they are evolving. He gives details on how these electronic devices process, store and receive information and how they work together under the control of computer software. Then he goes on to explain that increasingly sophisticated factories are needed to produce today’s higher performance semiconductor chips — and why the Congress has passed legislation designed to help ensure that next-generation semiconductors start to be manufactured in the United States.
