A semiconductor device includes a semiconductor element, a first lead supporting the semiconductor element, a second lead separated from the first lead, and a connection lead electrically connecting the semiconductor element to the second lead. The connection lead has an end portion soldered to the second lead. This connection-lead end portion has a first surface facing the semiconductor element and a second surface opposite to the first surface. The second lead is formed with a recess that is open toward the semiconductor element. The recess has a side surface facing the second surface of the connection-lead end portion. A solder contact area of the second surface of the connection-lead end portion is larger than a solder contact area of the first surface of the connection-lead end portion.

Aspects of the present disclosure relate to a molded electronic package and a method for manufacturing the same. The molded electronic package includes a first substrate, a second substrate, an electronic component arranged on the first substrate, a spring member arranged between the second substrate and the electronic component, the spring member including a first contact portion being fixated relative to the second substrate, and a second contact portion physically contacting the electronic component, and a body of solidified molding compound configured to encapsulate the electronic component and the spring member and to mutually fixate the first substrate, the second substrate, the electronic component and the spring member. The second substrate and the spring member are electrically and/or thermally conductive.
