The process to manufacture chips from a wafer starts with the layout and design phase. highly complex chips are made up of billions of integrated and connected transistors, enabling sophisticated circuits such as microcontrollers and crypto chips to be built on a semiconductor surface measuring just a few square millimeters in size.
As the manufacturing process for a given chip or production line is perfected, more and more of the chips will be good. the ratio of good to bad chips on a wafer is called the yield . yields well under 50 are common when a new chip starts production however, by the end of a given chips life, the yields are normally in the 90 range.
