Patent ID: 8008763

Claim:
A stacked semiconductor element, comprising: a substrate having electrode portions; a first electronic component, mounted on the substrate, having first electrode pads connected to the electrode portions via first bonding wires; a second electronic component, stacked on the first electronic component, having protruding portions including four sides respectively protruding outside from an outer periphery of the first electronic component, and second electrode pads disposed at upper surfaces of the protruding portions respectively and connected to the electrode portions via second bonding wires; a plurality of insulating columnar bodies supporting and adhered to lower surface surfaces of the protruding portions of the second electronic component respectively, each of the insulating columnar bodies having a planate portion in contact with one of the lower surfaces of the protruding portions, and a dam frame is provided at an outer periphery of one of the insulating columnar bodies, wherein: the insulating columnar bodies are spaced away from the first electronic component, each of the protruding portions is supported with a plurality of the insulating columnar bodies, and at least one of the insulating columnar bodies is located directly below one of the second electrode pads.
