Patent ID: 7974103

Claim:
A signal transfer member, comprising: a base film; a semiconductor chip mounted on the base film and operable to receive a first signal and to output a second signal in response thereto; an input interconnection formed on the base film and electrically connected to the semiconductor chip to receive the first signal from an external source and to provide the first signal to the semiconductor chip; and, an output interconnection formed on the base film and electrically connected to the semiconductor chip to receive the second signal from the semiconductor chip and to transmit the second signal to an external destination, and wherein the first signal comprises a chip power signal that drives the semiconductor chip and a chip control signal that causes the chip to output the second signal, wherein the input interconnection comprises: a plurality of input power lines that transmit the chip power signal, at least one of the plurality of input power lines being bent so as to incorporate a serpentine structure; and a plurality of input signal lines that transmit the control signal, and wherein the at least one of the plurality of input power lines is successively bent in a repeating pattern of a first direction, a second direction, and a third direction to have a length that is greater than a length of one of the input signal lines, the first direction is substantially parallel to one side of the base film in a plan view, the second direction is substantially perpendicular to the first direction in a plan view, and the third direction is substantially parallel to the second direction in plan view.
