Two-In-One Lead Frame Package
A lead frame package includes a first semiconductor chip, a second semiconductor chip, and a first lead frame. The first semiconductor chip is connected to a die attachment pad using a first clip. The second semiconductor chip is connected to the die attachment pad using a second clip. The die attachment pad is sandwiched between the first semiconductor chip and the second semiconductor chip. The first lead frame is connected to the die attachment pad.
POWER LEADFRAME PACKAGE WITH REDUCED SOLDER VOIDS
An electronic device includes an integrated circuit (IC) with its second face bonded to a first surface of a first support. A conductive clip has a first portion that is elongate and extends across the IC, having its second surface bonded to a first face of the IC by a solder layer. A second portion of the clip extends from the first portion away from the IC toward a second support with the second surface bonded to a first surface of the second support. A first surface of the clip has a pattern formed therein including a depressed floor with fins extending upwardly therefrom. Through-holes extend through the depressed floor to the second surface of the clip. An encapsulating layer covers portions of the first and second supports, IC, and clip while leaving the first surface of the first portion exposed to permit heat to radiate away therefrom.
SEMICONDUCTOR MODULE COMPRISING A FIRST AND SECOND CONNECTING ELEMENT FOR CONNECTING A SEMICONDUCTOR CHIP, AND ALSO PRODUCTION METHOD
