Patent ID: 7709945

Claim:
A multichip sensor comprising: a platy and rectangular detection chip for detecting a yaw rate of a vehicle, the detection chip having a thickness, a first side and a second side, the first side being shorter than the second side, and the thickness being less than the length of the first side and the length of the second side; a signal-processing IC chip for processing an output signal of the detection chip; and a package adapted to accommodate the detection chip and the signal-processing IC chip and having a vertical surface to be mounted on a circuit board of an electronic control unit of hydraulic devices, the package having a height dimension which is perpendicular to the vertical surface, a width dimension and a depth dimension, wherein the height dimension is less than both of the width dimension and the depth dimension of the package, and the direction along the first side of the detection chip is perpendicular to the vertical surface of the package.
