The 1-Inch Wafer Era of the 1960s. When silicon wafers were first used in semiconductor manufacturing in the early 1960s, 1-inch (25.4 mm) was the standard diameter. Some key traits of 1-inch wafers included:. Enabled the first integrated circuits (ICs); Limited to a few transistors per chip; Had high defect densities; Were manually …
silicon, ingots, are sliced into wafers, ground to a specific thickness (e.g., 300 mm diameter wafers are 0.775 mm thick) and polished to be smooth. A thin layer of epitaxial (i.e., single crystal) silicon, or "epi", is deposited using CVD and the wafer is ready for use in a fabrication facility (commonly called a fab). All the transistors ...
