Abstract: Disclosed is a method that determines critical areas associated with different types of fault mechanisms in an integrated circuit design. The invention does this by constructing individual Voronoi diagrams for critical areas of individual fault mechanisms and a composite Voronoi diagram based on the individual Voronoi diagrams. The invention computes the critical area for composite fault mechanisms of the integrated circuit design based on the composite Voronoi diagram.

Abstract: A semiconductor chip includes flip chip contacts that are arranged on contact surfaces of an active top side of the semiconductor chip. The contact surfaces are surrounded by a passivation layer that covers the active top side while leaving exposed the contact surfaces. The passivation layer includes thickened portions that surround the contact surfaces. The semiconductor chip formed with thickened portions around the contact surfaces is protected from delamination during packaging of the semiconductor chip to form a semiconductor device.

Abstract: A method and apparatus for controlling the tilt between the optical axis of an optical pick-up head and an optical disc applied in an optical disc drive is provided. A trapezoidal-wave signal in a radio frequency signal is received, wherein the trapezoidal-wave signal includes a rising edge and a falling edge. And a slope sum is calculated and so is an amplitude or a time domain area of the trapezoidal-wave signal. Then, a tangential tilt control parameter is generated according to the slope sum, and a radial tilt control parameter is generated according to the amplitude or the time domain area of the trapezoidal-wave signal. Thus, the optical disc drive is controlled according to the tangential tilt control parameter and the radial tilt control parameter for the optical axis of the optical pick-up head to be perpendicular to the optical disc.
