Abstract:
A semiconductor device structure for a three-dimensional integrated circuit has a semiconductor substrate having a plurality of through-substrate vias provided in the substrate, wherein three or more of the plurality of through-substrate vias are arranged in a hexagonal packing array with respect to their design-rule circle.
Abstract:
A coaxial electrical connector includes a tubular body, first, second and third insulator members, a contact piece, and a central conductor unit. The tubular body defines a through hole, and is formed with a radial hole. The first and second insulator members are mounted in the through hole and are spaced apart from each other. The third insulator member is mounted in the radial hole. The contact piece extends into the third insulator member. The central conductor unit is supported in the through hole by the first and second insulator members, and includes a first conductor component coupled telescopically to a second conductor component. The first conductor component is movable to make or break contact with the contact piece.
Abstract:
A wafer laser-marking method is provided. First, a wafer having a first surface (an active surface) and a second surface (a back surface) opposite to each other is provided. Next, the wafer is thinned. Then, the thinned wafer is fixed on a non-UV tape such that the second surface of the wafer is attached to the tape. Finally, the laser marking step is performed, such that a laser light penetrates the non-UV tape and marks a pattern on the second surface of the wafer. According to the laser-marking method of the embodiment, the pattern is formed by the non-UV residuals left on the second surface of the wafer, and the components of the glue residuals at least include elements of silicon and carbon.
Abstract:
A method for forming an electric device having power switches around a logic circuit including: forming a logic circuit on a substrate; forming a plurality of power switches around the logic circuit; and coupling first ends of the power switches to a voltage end, and coupling second ends of the power switches to a power receiver of the logic circuit.
