The invention of the transistor in 1947 at Bell Labs was the pivotal moment, but these early transistors were still point-contact devices soldered onto circuit boards. The history of the wafer is, in many ways, the history of photolithography, as the industry has continuously innovated to print smaller features, moving from micrometers to nanometers and beyond.

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. 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.
Far from being a simple disc, this thin slice of semiconductor material serves as the foundational canvas for the digital world. The industry is currently in a transition to 300mm (approximately 12-inch) wafers, a shift that occurred primarily in the early 2000s for advanced logic and memory production.
