    Abstract: A motor driving circuit is described for three-phase brushless DC motors, which have a three-phase-coil and first and second Hall sensors to detect the magnetic field of a rotor. The motor driving circuit includes first and second comparators, comparing a first and second pair of Hall signals from the Hall sensors, and outputting a first and second Hall signals. An adder unit receives the first and second pair of Hall signals to output a third pair of Hall signals to a third comparator, which outputs a third Hall signal. A motor driver is controlled by the first, second, and third Hall signals of the first, second and third comparators to change directions of currents flowing through phases of the three-phase coil accordingly to rotate the rotor of the motor. The first and second Hall signals can be amplified to match the level of the third Hall signal, or vice versa.

    Abstract: Methods for forming interconnect structures are provided herein. In some embodiments, a method for forming an interconnect on a substrate may include depositing a material atop an upper surface of the substrate and atop one or more surfaces of a feature disposed in the substrate by a first deposition process that deposits the material at a faster rate on the upper surface than on a bottom surface of the feature; depositing the material atop the upper surface of the substrate and atop one or more surfaces of the feature by a second deposition process that deposits the material at a greater rate on the bottom surface of the feature than on the upper surface of the substrate; and heating the deposited material to draw the deposited material towards the bottom surface of the feature to at least partially fill the feature with the deposited material.
