Abstract

The invention discloses a semiconductor assembly, in particular a power module semiconductor assembly including a flexible circuit board and a method for manufacturing such an assembly. The semiconductor assembly includes a flexible circuit board, a conductive film on a first portion of the upper surface of the flexible circuit board, a solder pad on a second portion of the upper surface of the flexible circuit board, a heat sink on a portion of the bottom surface of the flexible circuit board , passive components, separate devices, or IC devices connected to a part of the conductive film, and the leads of the lead frame connected to the pads. These components can have component placement with high design flexibility and easy wiring design, reducing the time to design the components and reducing the cost of the components. Other embodiments are also described.

Description

technical field [0001] The present application relates generally to semiconductor components and methods of making such components. More specifically, the present application describes power module semiconductor assemblies including flexible circuit boards and methods of making such assemblies. Background technique [0002] Semiconductor components are known in the art. Typically, these components may include one or more semiconductor devices, such as integrated circuit (IC) chips, which may be connected to die pads that are collectively formed in a leadframe. Bond wires sometimes electrically connect the integrated circuit chip to a series of terminal devices that serve as power connections for external devices such as printed circuit boards ('PCBs'). Encapsulation materials may be used to cover bond wires, integrated circuit chips, terminal equipment, and / or other components to form the exterior of the semiconductor assembly. A portion of the end device and perhaps a po...
