Patent ID: 8807708

Claim:
A semiconductor device in which a plurality of segments are arranged on a semiconductor substrate, each segment including a plurality of driving units for discharging a liquid in nozzles, each driving unit including a driving circuit and an element which is driven by the driving circuit to apply, to the liquid, energy for discharging the liquid in the nozzle, wherein the semiconductor device includes an input pad and a plurality of conductive patterns electrically connected to the input pad, each of the conductive patterns includes a first conductive portion which is connected to the input pad and is elongated in a first direction, a second conductive portion which is elongated in the first direction, a third conductive portion which is connected to one of the plurality of driving units, and a connection portion which connects the second conductive portion and the third conductive portion, a dimension of each of the second conductive portions in a second direction perpendicular to the first direction is greater than a dimension of a corresponding one of the first conductive portions in the second direction, each of the second conductive portions is connected to the corresponding one of the first conductive portions at a side nearer to the input pad than a center line of the second conductive portion in the first direction, and connected to a corresponding one of the connection portions at a side farther from the input pad than the center line, and each of the third conductive portions is elongated from a portion connected to the corresponding one of the connection portions in the first direction.
