Abstract:
A host substrate and method of making a host substrate for nitride based thin-film semiconductor devices are provided. According to one embodiment, the method includes the steps of providing a silicon layer; etching a pattern of holes in the silicon layer; plating the silicon layer with copper to fill the holes etched in the silicon layer; bonding the silicon layer to a gallium nitride (GaN) layer, the GaN layer attached to a sapphire substrate; and removing the sapphire substrate. The host substrate is configured to address the coefficient of thermal expansion (CTE) mismatch problem and reduce the amount of stress resulting from such CTE mismatch. A combination of metal and semiconductor materials provide for the desired thermal and electrical conductivity while providing for subsequent dicing and incorporation of the finished semiconductor devices into other circuits.

Abstract:
An electrical connector (100) includes an insulative housing (1) defining at least a passageway (11) and a mating face (101), at least a contact terminal (2) received in the passageway (11) and having a contact arm (24) extending beyond the mating face (101). The contact terminal (2) includes a base portion (23) with a cutout (233) providing a yielding space to receive a portion (241) of the contact arm (24) when it is depressed.
Abstract:
A method of aligning electronic components comprising providing a positioning member 110 having at least one formation 120 for receiving an electronic component; said at least one formation having lateral boundaries 35, 36 for constraining movement of an electronic component; placing a first electronic component 10a in said at least one formation; and providing a force for actively aligning said first electronic component with a lateral boundary of said at least one formation. The force may, for example, be provided by tilting the positioning member, by providing suction or by using an actuator. An apparatus for aligning electronic components and a 3D system of stacked electronic components is also disclosed.
Abstract:
There is described a method of forming a through-silicon-via to form an interconnect between two stacked semiconductor components using pulsed laser energy. A hole is formed in each component, and each hole is filled with a plug formed of a first metal. One component is then stacked on another component such that the holes are in alignment, and a pulse of laser energy is applied to form a bond between the metal plugs.
