摘要:
A configuration comprising a magnetic sensor and a pointing control circuit, for implementing a pointing device, is rendered compact in size.To that end, the pointing control circuit is formed in the central part of an IC chip, substantially square in shape, and Hall elements are provided in four corners of the peripheral region of the pointing control circuit, respectively, thereby forming the magnetic sensor, comprising the Hall elements, integrally with the pointing control circuit. Further, the Hall elements are formed integrally with the pointing control circuit in the step of fabricating an IC, thereby uniting the Hall elements with the pointing control circuit.
