<p><P>PROBLEM TO BE SOLVED: To miniaturize a structure comprising a magnetic sensor and a pointing control circuit, for use in a pointing device. <P>SOLUTION: A substantially square IC chip has the pointing control circuit in a central portion and has Hall elements in four corner portions around the pointing control circuit, so that the magnetic sensor comprising the Hall elements, and the pointing control circuit are integrated. The Hall elements and the pointing control circuit are fabricated in an IC manufacturing process, and the Hall elements and the pointing control circuit are integrated. <P>COPYRIGHT: (C)2004,JPO</p> |
