Silicon Ingot

Term from Semiconductor Manufacturing industry explained for recruiters

A Silicon Ingot is a large, cylindrical piece of pure silicon that serves as the starting material for making computer chips and electronic components. Think of it like a large crystal rolling pin made of extremely pure silicon. Companies use these ingots by slicing them into thin wafers, which then become the foundation for creating computer chips. This is a fundamental material in the semiconductor industry, and you'll often see it mentioned in manufacturing or process engineer resumes. When candidates mention working with silicon ingots, they're typically involved in the early stages of semiconductor production.
