摘要： An integrated circuit device is provided which comprises a substrate, a conductive line configured to experience a pressure, and a magnetic tunnel junction (“MTJ”) core formed between the substrate and the current line. The conductive line is configured to move in response to the pressure, and carries a current which generates a magnetic field. The MTJ core has a resistance value which varies based on the magnetic field. The resistance of the MTJ core therefore varies with respect to changes in the pressure. The MTJ core is configured to produce an electrical output signal which varies as a function of the pressure.

摘要： An integrated circuit device includes a magnetic random access memory (“MRAM”) architecture and at least one inductance element formed on the same substrate using the same fabrication process technology. The inductance element, which may be an inductor or a transformer, is formed at the same metal layer (or layers) as the program lines of the MRAM architecture. Any available metal layer in addition to the program line layers can be added to the inductance element to enhance its efficiency. The concurrent fabrication of the MRAM architecture and the inductance element facilitates an efficient and cost effective use of the physical space available over active circuit blocks of the substrate, resulting in three-dimensional integration.

摘要： Methods and apparatus are provided for sensing physical parameters. The apparatus comprises a magnetic tunnel junction (MTJ) and a magnetic field source whose magnetic field overlaps the MTJ and whose proximity to the MTJ varies in response to an input to the sensor. The MTJ comprises first and second magnetic electrodes separated by a dielectric configured to permit significant tunneling conduction therebetween. The first magnetic electrode has its spin axis pinned and the second magnetic electrode has its spin axis free. The magnetic field source is oriented closer to the second magnetic electrode than the first magnetic electrode. The overall sensor dynamic range is extended by providing multiple electrically coupled sensors receiving the same input but with different individual response curves and desirably but not essentially formed on the same substrate.

摘要： A semiconductor process and apparatus provide a high-performance magnetic field sensor from two differential sensor configurations (201, 211) which require only two distinct pinning axes (206, 216), where each differential sensor (e.g., 201) is formed from a Wheatstone bridge structure with four unshielded MTJ sensors (202-205), each of which includes a magnetic field pulse generator (e.g., 414) for selectively applying a field pulse to stabilize or restore the easy axis magnetization of the sense layers (e.g., 411) to eliminate micromagnetic domain switches during measurements of small magnetic fields.

摘要： In accordance with a specific embodiment, a method of processing a semiconductor substrate is disclosed whereby the substrate is thinned, and the dice formed on the substrate are singulated by a common process. Trench regions are formed on a backside of the substrate. An isotropic etch of the backside results in a thinning of the substrate while maintaining the depth of the trenches, thereby facilitating singulation of the die.
