Abstract:
1. A dynamic quantity sensor comprising: a sensor chip including a semiconductor substrate, a sensor part formed on the semiconductor substrate, and a plurality of first pads disposed on a surface of the semiconductor substrate and electrically coupled with the sensor part; a base member including a substrate and a plurality of second pads disposed on a surface of the substrate opposing to the surface of the semiconductor substrate; and a plurality of bumps mechanically and electrically coupling the plurality of first pads and the plurality of second pads, wherein the sensor chip is coupled with the base member in a state where the sensor chip is curved with respect to the base member, wherein the plurality of first pads includes a plurality of first input pads that inputs a signal to the sensor part and a plurality of first output pads that outputs a signal from the sensor part, wherein one of the plurality of first input pads is disposed on a portion of the surface of the semiconductor substrate at which an opposing distance between the sensor chip and the base member is shorter, and wherein one of the plurality of first output pads is disposed on a portion of the surface of the semiconductor substrate at which an opposing distance between the sensor chip and the based member is longer.
