Abstract

A chip mounting plate construction of lead frames for semiconductor packages which provides a chip mounting plate having a greatly reduced area to obtain a small bonding area between the chip mounting plate and a semiconductor chip mounted on the chip mounting plate, thereby capable of minimizing thermal strain generated at the chip mounting plate due to a thermal expansion thereof. The chip mounting plate is constructed to have a smaller area than the semiconductor chip, to have a central opening, or to have recesses.
