This power point presentation discusses semiconductors and their role in modern electronics. Semiconductors are materials that have properties between conductors and insulators, and when impurities are added they can be used to create transistors. The first semiconductor was created in 1947 and led to the development of the transistor radio. Integrated circuits allowed many transistors to be placed on a single semiconductor, enabling complex devices like microprocessors. Moore's Law describes how the number of transistors doubles every two years while costs are halved, driving advances, but physical limits are now being approached. The future of semiconductors remains exciting as new technologies require new materials and components.
