发明名称 SEMICONDUCTOR DEVICE WITH WELDED LEADS AND METHOD OF MANUFACTURING THE SAME
摘要 A semiconductor device and a manufacturing method for preventing mechanical and thermal damage to the semiconductor chip. A laser beam welds a first connection pad formed on a first external lead to a first electrode formed on the surface of the semiconductor chip. A first connection hole is formed in the first connection pad, and the first connection hole overlaps the first connection electrode. A laser beam irradiates an area including the first connection hole, and the first connection pad in a portion around the first connection hole is melted to form a melting section, that is welded to the first connection electrode to easily form a semiconductor device with more excellent electrical characteristics.
