Packaged power devices having vertical power mosfets therein that are flip-chip mounted to slotted gate electrode strip lines

摘要

Packaged power devices include an electrically conductive flange having a slot therein and an electrically conductive substrate mounted within the slot. A dielectric layer is provided on the electrically conductive substrate and a gate electrode strip line is patterned on the dielectric layer. The gate electrode strip line extends opposite the electrically conductive substrate. A vertical MOSFET is also provided. The vertical MOSFET has a source electrically coupled and mounted to a first portion of the flange located outside the slot and a gate electrode electrically coupled and mounted to a first end of the gate electrode strip line.
