Abstract:
1. A power module having a stacked flip-chip, comprising: a lead frame; a control device part comprising a control device chip; a power device part comprising a power device chip and being electrically connected to the lead frame; and an interconnecting substrate on which the control and power device parts are respectively disposed at upper and lower portions, a thermal substrate coupled to the power device chin, wherein the thermal substrate emits heat generated from the power device part, wherein each of the control and power device chips is attached to one of the lead frame and the interconnecting substrate using a plurality of flip-chip electrical bonds, wherein the lead frame comprises first and second lead frame portions, wherein the first lead frame portion has a first portion that extends underneath the interconnecting substrate, and the second lead frame portion has a second portion that extends on an upper surface of the interconnecting substrate, wherein the first portion is longer than the second portion, wherein the power device part is disposed between the first lead frame portion and the thermal substrate, and wherein the power device chip of the power device part is attached to a lower surface of the first lead frame portion using at least one electrical bond.
