Abstract: An electronic device, e.g. a trimmable resistor, includes a plurality of fused resistors, each fused resistor including one or more doped resistive regions formed in a semiconductor substrate. The doped resistive regions may be thermistors. Each fused resistor further includes a corresponding one of a plurality of fusible links. A first terminal of each of the fused resistors is connected to a first terminal of the corresponding fusible link. First and second interconnection buses are located over the substrate, with the first interconnection bus connecting to a second terminal of each of the fused resistors, and the second interconnection bus connecting to a second terminal of each of the fusible links. The plurality of fused resistors have resistance values that form an exponential progression.

Abstract: An integrated fluxgate device has a magnetic core disposed over a semiconductor substrate. A first winding is disposed in a first metallization level above and a second metallization level below the magnetic core, and is configured to generate a first magnetic field in the magnetic core. A second winding is disposed in the first and second metallization levels and is configured to generate a second magnetic field in the magnetic core. A third winding is disposed in the first and second metallization levels and is configured to sense a magnetic field in the magnetic core that is the net of the first and second magnetic fields.

Abstract: An integrated fluxgate device, which includes a magnetic core, an excitation coil, and a sense coil. The magnetic core has a longitudinal edge and a terminal edge. The excitation coil coils around the longitudinal edge of the magnetic core, and the excitation coil has a first number of excitation coil members within a proximity of the terminal edge. The sense coil coils around the longitudinal edge of the magnetic core, and the sense coil has a second number of sense coil members within the proximity of the terminal edge. For reducing fluxgate noise, the second number of sense coil members may be less than the first number of excitation coil members within the proximity of the terminal edge.

Abstract: An example apparatus includes a semiconductor wafer with a plurality of probe pads each formed centered in scribe streets and intersected by saw kerf lanes. Each probe pad includes a plurality of lower level conductor layers arranged in lower level conductor frames, a plurality of lower level vias extending vertically through lower level insulator layers and electrically coupling the lower level conductor frames; a plurality of upper level conductor layers, each forming two portions on two outer edges of the probe pad, the two portions aligned with, spaced from, and on opposite sides of the saw kerf lane, the coverage of the upper level conductor layers being less than about twenty percent; and a plurality of upper level vias extending vertically through upper level insulator layers and coupling the upper level conductor layers electrically to one another and to the lower level conductor layers. Methods are disclosed.
