Abstract:
A semiconductor package includes a lead frame having a displaced integral strap which is cupped out of a lead frame plane to provide a nest that receives a semiconductor chip electrically connected to an inner surface of the cupped strap. The semiconductor package further has a housing molded over and encapsulating the semiconductor chip with the frame such that a surface of the semiconductor chip facing away from the cupped strip is flush with or protrudes beyond a bottom of the housing.
Abstract:
A driver stage consisting of an N channel FET and a P channel FET are mounted in the same package as the main power FET. The power FET is mounted on a lead frame and the driver FETs are mounted variously on a separate pad of the lead frame or on the main FET or on the lead frame terminals. All electrodes are interconnected within the package by mounting on common conductive surfaces or by wire bonding. The drivers are connected to define either an inverting or non-inverting drive.

Abstract:
A peripheral electronic system for an electronic device including a motherboard having multiple individual electrically connected vertically stacked modules, at least one of which is a circuit board assembly including active and/or passive electronic components embedded therein with the components being electrically connected by conductive traces to provide desired operating function. The peripheral electronic system further includes an electrical connector array on an exposed surface of the composite structure to provide electrical connections between the peripheral electronic system and the motherboard.
Abstract:
A flip chip structure contains laterally spaced semiconductor devices such as MOSFETs in a common chip. A deep trench isolates the devices. Contacts are connected to the source drain and gate electrode (or other electrodes) and are interconnected as required for a circuit function either within the chip or on the support board. Ball contacts are connected to the electrodes. The opposite surface of the chip to that in which the devices are formed receives a copper or other metal layer which is patterned to increase its area for heat exchange. The surface of the copper is coated with black oxide to increase its ability to radiate heat.
