Abstract: Systems and methods for monitoring copper corrosion in an integrated circuit (IC) device are disclosed. A corrosion-sensitive structure formed in the IC device may include a p-type active region adjacent an n-type active region to define a p-n junction space charge region. A copper region formed over the silicon may be connected to both the p-region and n-region by respective contacts, to thereby define a short circuit. Light incident on the p-n junction space charge region, e.g., during a CMP process, creates a current flow through the metal region via the short circuit, which drives chemical reactions that cause corrosion in the copper region. Due to the short circuit configuration, the copper region is highly sensitive to corrosion. The corrosion-sensitive structure may be arranged with less corrosion-sensitive copper structures in the IC device, with the corrosion-sensitive structure used as a proxy to monitor for copper corrosion in the IC device.

Abstract: An apparatus for inductive linear-position sensing is disclosed. An apparatus may include a support structure and an electrically conductive material defining a continuous path for electrical current to flow between a first location and a second location. The continuous path may include: a first path portion defining a first spiraling path for the electrical current to flow in a clockwise direction around a first axis; a second path portion laterally spaced from the first path portion and defining a second spiraling path for the electrical current to flow in a counter-clockwise direction around a second axis; a first coupling portion coupling an inner portion of the first path portion to an inner portion of the second path portion; and a second coupling portion coupling an outer portion of the second path portion to an outer portion of the first path portion.

Abstract: Object detection in wireless power systems and related system, methods, and devices are disclosed. A controller for a wireless power transmitter includes a measurement voltage potential input terminal and a processing core. The processing core is to determine an average of peak to peak amplitude differences present in sampled measurement voltage potentials for each of the plurality of transmit coils, determine a lowest average of the peak to peak amplitude differences, and select a transmit coil corresponding to the lowest average of the peak to peak amplitude differences to transmit wireless power to a receive coil of a wireless power receiver. A wireless power system includes a tank circuit selectively including any one of a plurality of transmit coils.

Abstract: An apparatus comprises a target to rotate about an axis; an excitation coil to carry an excitation signal; and a first sense coil to carry a sense signal induced by the excitation signal. The first sense coil comprises two or more lobes in one or more planes that are perpendicular to the axis. The two or more lobes comprise a first lobe at a first position relative to the axis and a second lobe at a second position relative to the axis. The second position is substantially the same radial distance from the axis as the first position is from the axis. The second position is at an angular distance of Θ from the first position, where Θ=180°±α/2, and α is a measurement range for angular-position sensing (e.g., α=60°) within a range of 50% to 150% of α.
