The move to planar technology in the late 1950s was revolutionary. The diameter of these ingots has grown over time, evolving from mere inches to over 300 millimeters, allowing for more dies per wafer and greater efficiency in production.
Wafer History Fairchild Kilby: The Genesis of Planar Technology
The creation of a wafer starts with a silicon ingot, grown using the Czochralski process. The perfection of this crystal lattice is paramount; any impurities or structural defects can disrupt the flow of electricity through the microscopic pathways carved into it.
From the earliest days of computing to the era of artificial intelligence, the wafer has been the silent enabler of technological progress. The wafer undergoes hundreds of steps in a cleanroom, where it is exposed to photolithography, etching, doping, and deposition.
