Abstract:
1. A method of fabricating a power module, comprising: forming bumps on power and control device chips on a wafer level; separately sawing the power and control device chips into individual chips; adhering the power device chip onto a thermal substrate and the control device chip onto an interconnecting substrate; combining a lead frame, the thermal substrate, and the interconnecting substrate with one another in a multi-jig; and sealing the power and control device chips, wherein the control and power device chips are attached to one of the lead frame and the interconnecting substrate using a flip-chip bonding method, wherein the lead frame comprises first and second lead frame portions, wherein the first lead frame portion extends underneath the interconnecting substrate, and the second lead frame portion extends on the interconnecting substrate; 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 a flip-chip bonding method.
