WebA photolithographic "printing" process is used to form a chip's multilayered transistors and interconnects (electrical circuits) on a wafer. Hundreds of identical processors are created in batches on a single silicon wafer. Title, date and keywords based on information provided by the photographer. Gift; Barbara Barrett; 2024; (DLC/PP-2024:112) WebDec 30, 2024 · 4 Answers. Sorted by: 15. The minimum area of the chip is determined by the most cost effective solution not the smallest physical possible cut. The smallest cut defect-free with a kerf is roughly equal to the wafer thickness and the slotted diamond saw roughly equal to 1/2 of the wafer thickness.
