PACKAGED ASSEMBLY FOR HIGH DENSITY POWER APPLICATIONS

摘要

A packaged assembly for high density power applications includes a case having shelves on opposing walls, and a double-sided substrate disposed on the shelves of the case, the double-sided substrate having a semiconductor die on a first side of the double-sided substrate and circuit elements on a second side of the double-sided substrate. The case includes aluminum silicon (AlSi). The double-sided substrate is secured to the case by an epoxy. The double-sided substrate a thick film substrate and includes beryllium oxide (BeO) or aluminum oxide (Al₂O₃). The semiconductor die on the first side of the double-sided substrate is coupled to at least one of the circuit elements on the second side of the double-sided substrate by a through substrate via. The packaged assembly also further includes invertible leads coupled to the double-sided substrate by lead frames.
