Title:
【発明の名称】半導体装置
Document Type and Number:
Japanese Patent JP2716524
Kind Code:
B2
Abstract:
PURPOSE:To enable a wire to be strongly joined to an external terminal by providing a projecting part which deeply bites into the inside of a sheathing member on the rear surface of the external terminal for allowing a supersonic energy to be transmitted efficiently to the external terminal. CONSTITUTION:A projecting part 10 projecting toward a projecting piece 6b side of a sheathing member 6 is provided at both edges of the tip part on the rear surface of external terminals 4 and 5 and the tip part of the external terminals 4 and 5 are formed nearly in U shape when viewed from the front. In these external terminals 4 and 5, both projecting parts 10 bite deeply into the inside of a protruding piece 6b, thus enabling the external terminals 4 and 5 to be retained strongly to the sheathing member 6. It prevents the external terminals 4 and 5 from being vibrated when supersonic wire bonding gives vibration to the external terminals 4 and 5, thus enabling the supersonic energy to be transmitted efficiently to the external terminals 4 and 5 and enabling a wire 8 to be jointed strongly to bonding pads 4a and 5a of the external terminals 4 and 5.
