发明名称 Semiconductor device
摘要 A semiconductor device comprises an inverted-tray-shaped support frame having a concave inner surface, a semiconductor element supported by the support frame at the center of its inner surface, and a plurality of leads which are formed on the inner surface of the support frame over an insulative layer interposed therebetween, and which extend from the center of the support frame outward to the periphery hereof and are electrically connected at their inner root ends to respective electrodes of the semiconductor element. The support frame reinforces and preserves the mechanical strength of the leads, which can therefore be spaced more closely and accurately.
