Patent ID: 7816780

Claim:
A semiconductor apparatus comprising: a semiconductor device having a first principal surface and a second principal surface positioned in mutually opposite sides; a first metal member electrically connected to a first electrode formed over the first principal surface via conductive resin composed of an organic binder mixed with metal powder including precious metal by 65 to 98 wt %; a first precious metal layer formed by fusing with a surface of the first electrode opposed to the first metal member; and an insulating encapsulant enclosing the semiconductor device, wherein the surface of the first electrode opposed to the first metal member is composed of precious metal, wherein a thickness of the first precious metal layer is 50 nm to 3 μm, wherein a surface of the first precious metal layer has a first hole portion plurally in number, wherein the first hole portion has a first opening portion and a second opening portion sequentially along a first direction directed from the first electrode to the first metal member, and wherein a bulging portion composed of precious metal constituting the first precious metal layer and covering the first opening portion is formed in the second opening portion.
