    Abstract: A power semiconductor device includes: at least one substrate; at least one power semiconductor die arranged over the at least one substrate; a first leadframe arranged over the at least one power semiconductor substrate and over the at least one power semiconductor die, the first leadframe being arranged at least partially in a first plane and including one or more connecting portions extending out of the first plane in a first direction; and a second leadframe at least partially arranged in a second plane above or below the first plane and including one or more attachment sites. The one or more connecting portions extend into the second plane at the one or more attachment sites. The one or more connecting portions are arranged at a non-zero distance from the second leadframe, the non-zero distance being bridged by weld seams at the one or more attachment sites.
