Nowadays, semiconductor devices, also referred as integrated circuits and microchips are essential components in everyday electronic products. Silently they are the heroes of the technological world: they work, power, pilot, control an ever-increasing number of objects - from toys to wrist watches, from smartphones to cars and home automation products. Thanks to technological improvements such as the increasing computational capacity of chips, ever larger and faster memories, the ability to execute artificial intelligence algorithms and the reduction of their production cost, a radical change has been observed in the way we live and work. This improvement has brought challenges never faced before for companies, which have had the need to produce increasingly complex chips, while maintaining high quality standards, trying not to fall into excessive delays.
