The invention provides a wire-bonding type semiconductor device including, a semiconductor chip, a plurality sets of electrode pads formed on the semiconductor chip, each set including a power supply electrode, at least one signal electrode pad and a gland electrode pad arranged in this order, a mount on which the semiconductor chip is placed, the mount being formed with the same number of extensions as the number of the gland electrode pads, the extension acting as gland leads, the same number of power supply leads as the number of the power supply electrode pads, the same number of signal leads as the number of the signal electrode pads, the power supply leads, the signal leads and the projections acting as gland leads being arranged in this order, and metal wires for connecting each of the power supply electrode pads, signal electrode pads and gland electrode pads to the power supply leads, the signal leads and the extensions, respectively, the metal wires being disposed substantially in parallel with one another and having substantially the same length. The invention makes it possible to remarkably reduce effective inductance of thin metal wires, and thus provides a high-speed operable semiconductor device which can be fabricated by conventional wire-bonding techniques and has significantly low gland bounce noise and cross-talk which would be caused by concurrent switching.
