Claim:
1. A method of forming a power semiconductor package, comprising: coupling a first face of each of a plurality of die with one of a plurality of connection traces of a first face of a first direct bonded copper (DBC) substrate using sintering paste; coupling a second face of each of the plurality of die with one of a plurality of connection traces of a first face of a second DBC substrate using sintering paste, wherein the first DBC substrate and second DBC substrate each comprise a double DBC substrate comprising a ceramic plate sandwiched between a first copper layer and a second copper layer, wherein the first copper layer of the first DBC substrate comprises the connection traces of the first DBC substrate and wherein the first copper layer of the second DBC substrate comprises the connection traces of the second DBC substrate; sintering the sintering paste using heat and pressure; and filling a cavity between the first face of the first DBC substrate and the first face of the second DBC substrate with an encapsulating compound forming a power semiconductor package.
