One of the most important technologies in use today is also one of the smallest. The microchip was invented in Scotland in 1947 and is now at the heart of the electronics industry. This unit uses video clips to explore how the microchip is made and how it works, and to predict the future of this incredible technology. This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.
