Abstract:
1. A semiconductor device comprising: a base electrode; a semiconductor chip having a rectifying function attached to said base electrode by a first bonding member; a lead electrode for connection with a lead wire, attached to an upper surface of said semiconductor chip by a second bonding member; and a first stress relief member which reduces stress developed in said first bonding member, wherein both said base electrode and said first stress relief member are in direct contact with a surface of said first bonding member which faces said base electrode, wherein at least one protrusion is formed upstanding from said base electrode on a side of said semiconductor chip, and said protrusion is in direct contact with the surface of said first bonding member which faces said base electrode, and wherein said first stress relief member is disposed surrounding a circumferential surface of said protrusion.
