The tiny chips powering billions of electronic devices are central to the global economy. Semiconductors, also sometimes referred to as microchips or integrated circuits, are made from tiny fragments of raw materials, such as silicon. They are altered through a process called doping in order to sometimes conduct electricity and sometimes not. This allows them to be used as electronic switches, speaking the binary language of 0s and 1s that underpins computing. Semiconductors are used in...
