A die (pronunciation: /dʌɪ/) in the context of integrated circuits is a small block of semiconducting material, on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die. To simplify handling and integration onto a printed circuit board, most dice are packaged in various forms. There are three commonly used plural forms: dice, dies, and die.
