摘要： A Lorentz magnetoresistive sensor having integrated signal amplification. The sensor is constructed upon a substrate such as a semiconductor material, and an amplification circuit such as transistor is constructed directly into the substrate on which the magnetoresistive device is constructed. This integrated signal amplification greatly enhances sensor performance by eliminating a great deal of signal noise that would otherwise be added to the read signal.

摘要： A Lorentz Magnetoresistive sensor having an extremely small lead width and lead spacing is disclosed. The sensor can be constructed by a novel fabrication method that allows the leads to be deposited in such a manner that lead width and spacing between the leads is determined by the as deposited thicknesses of the lead layers and electrically insulating spacer layers between the leads rather than by photolithography. Because the lead thicknesses and lead spacings are not defined photolithograhically, the lead thickness and lead spacing are not limited by photolithographic resolution limits.
