An Application of New 3D MCP Packaging Process for Al Wire Power Devices

Abstract

Traditional power devices packaging have been low package ratio, and difficult highly about the characteristic of the integrated, can't to adapt to the high integration and high density development trend in the semiconductor packaging industry; In this paper, a new design of Al wire cleaver face, can form a plane on the surface of Al wire or ribbon, realize the second die bond or wire bond on the surface of point. Through the process to achieve the idea that it can be applied to power devices of MCP packaging technology.
