Title:
SEMICONDUCTOR DEVICE AND MAGNETO-RESISTIVE SENSOR INTEGRATION
Document Type and Number:
WIPO Patent Application WO2005003801
Kind Code:
A3
Abstract:
A magnetic-sensing apparatus and method of making and using thereof is disclosed. The sensing apparatus may be fabricated from semiconductor circuitry and a magneto-resistive sensor. A dielectric may be disposed between the semiconductor circuitry and the magneto-resistive sensor. In one embodiment, the semiconductor circuitry and magneto resistive sensor are formed into a single package or, alternatively, monolithically formed into a single chip. In another embodiment, some of the semiconductor circuitry may be monolithically formed on a first chip with the magneto-resistive sensor, while other portions of the semiconductor circuitry may be formed on a second chip. As such, the first and second chips may be placed in close proximity and electrically connected together or alternatively have no intentional electrical interaction.
