    摘要: A virtually substrate-less composite power semiconductor device (VSLCPSD) and method are disclosed. The VSLCPSD has a power semiconductor device (PSD), a front-face device carrier (FDC) made out of a carrier material and an intervening bonding layer (IBL). Both carrier and IBL material can be conductive or non-conductive. The PSD has back substrate portion, front semiconductor device portion with patterned front-face device metallization pads and a virtually diminishing thickness TPSD. The FDC has patterned back-face carrier metallizations contacting the front-face device metallization pads, patterned front-face carrier metallization pads and numerous parallelly connected through-carrier conductive vias respectively connecting the back-face carrier metallizations to the front-face carrier metallization pads. The FDC thickness TFDC is large enough to provide structural rigidity to the VSLCPSD. The diminishing thickness TPSD effects a low back substrate resistance and the through-carrier conductive vias effect a low front-face contact resistance to the front-face device metallization pads.
