A first set of semiconductor substrates includes semiconductor chips having bonding pads arranged in a primary pattern. A second set of semiconductor substrates includes semiconductor chips having bonding pads arranged in a mirror-image pattern. A first semiconductor substrate from the first set is bonded to a second semiconductor substrate from the second set such that each bonding pads is bonded to a mirror-image bonding pad. Additional substrates are bonded sequentially such that the bonded structure includes an even number of semiconductor substrates of which one half have bonding pads of the primary pattern and are bonded to the side of the first semiconductor substrate, while the other half have bonding pads of the mirror-image pattern and are bonded to the side of the second semiconductor substrate. The mirror-image patterns of the bonding pads enable maximal cancellation of wafer bow.

A useful lifetime of an energy storage device can be extended by providing a series connection of a battery cell and an self-programming fuse. A plurality of series connections of a battery cell and an self-programming fuse can then be connected in a parallel connection to expand the energy storage capacity of the energy storage device. Each self-programming fuse can be a strip of a metal semiconductor alloy material, which electromigrates when a battery cell is electrically shorted and causes increases in the amount of electrical current therethrough. Thus, each self-programming fuse is a self-programming circuit that opens once the battery cell within the same series connection is shorted.

Improved nano-electromechanical system devices and structures and systems and techniques for their fabrication. In one embodiment, a structure comprises an underlying substrate separated from first and second anchor points by first and second insulating support points, respectively. The first and second anchor points are joined by a beam. First and second deposition regions overlie the first and second anchor points, respectively, and the first and second deposition regions exert compression on the first and second anchor points, respectively. The compression on the first and second anchor points causes opposing forces on the beam, subjecting the beam to a tensile stress. The first and second deposition regions suitably exhibit an internal tensile stress having an achievable maximum varying with their thickness, so that the tensile stress exerted on the beam depends at least on part on the thickness of the first and second deposition regions.

A multivariable solver for proximity correction uses a Jacobian matrix to approximate effects of perturbations of segment locations in successive iterations of a design loop. The problem is formulated as a constrained minimization problem with box, linear equality, and linear inequality constraints. To improve computational efficiency, non-local interactions are ignored, which results in a sparse Jacobian matrix.

An electric motor comprises a stator and a rotor rotatably mounted confronting the stator. The rotor has a rotor core which comprises at least a first tooth, a second tooth and a third tooth which are adjacent. Each of the teeth comprises a rib section radially and outwardly extending from a core and a tooth section located at an outer end of the rib section. The angle between the first tooth and the second tooth is n degrees, wherein when the rotor core is rotated n degrees to move the first tooth towards the second tooth, the rotated second tooth does not coincide with the pre-rotated third tooth.

A high-voltage, super-voltage and heavy current breaker is formed by combining intelligent optical vacuum breaker modules (21) with phase selection function in series and/or parallel connection. Each vacuum breaker module (21) is connected each other in series after being connected in parallel with a resistance capacitance device or with a resistance capacitance device and a zinc oxide arrester valve plate (22). Tight coupling reactors are connected with several serial branches of the vacuum breaker module (21) simultaneously to achieve parallel connection of several serial branches of the vacuum breaker module (21). The breaker distributes the high-voltage and heavy current into the low voltage and low current serial and parallel vacuum breaker modules (21) to share.
