PROBLEM TO BE SOLVED: To provide a resistance array capable of being highly accurately adjusted to a desired resistance value, an output buffer including the resistance array, and a method of manufacturing a semiconductor device.SOLUTION: A resistance array includes: a plurality of series resistance sections R1-Rn each of which includes a plurality of resistances connected in series; and a common line that connects one end of each of the series resistance sections in common. In each of the series resistance sections of the resistance array, both ends of each of the resistances excluding at least one resistance of each of the plurality of resistances or both ends of a resistor string are short circuited by a conductive line, and thereby the resistance value of the resistance array is adjusted to a desired resistance value.SELECTED DRAWING: Figure 1 【課題】精度良く所望の抵抗値に調整することが可能な抵抗アレイ、この抵抗アレイを有する出力バッファ、及び半導体装置の製造方法を提供することを目的とする。【解決手段】直列接続された複数の抵抗を夫々が含む複数の直列抵抗部Ｒ１〜Ｒｎと、直列抵抗部各々の一端同士を共通に接続する共通ラインとを含む抵抗アレイの、各直列抵抗部において、複数の抵抗各々のうちの少なくとも１の抵抗を除く各抵抗の両端又は抵抗列の両端を導電性ラインで短絡することにより、当該抵抗アレイの抵抗値を所望の抵抗値に調整する。【選択図】図１
