Abstract
A terminal land frame includes a frame body and a plurality of lands. Each of these lands is formed out of the frame body to be connected to the frame body via a thinned portion and protrude therefrom. When the lands are pressed in a direction in which the lands protrude from the frame body, the thinned portions are fractured and the lands are easily separable from the frame body. A semiconductor chip is mounted on some of the lands of the terminal land frame, and the chip, wires, etc. are single-side-molded with a resin encapsulant. Thereafter, when the lands are pressed on the bottom, the lands are separated from the frame body. As a result, a structure, in which the lower part of each of these lands protrudes downward from the lower surface of the resin encapsulant, is obtained, and protruding portion is used as an external electrode.
