Abstract
A semiconductor device is provided with a metal header of a size sufficiently small such that only a semiconductor element holding plate which requires heat dissipation can be mounted thereon. The metal header supports at its upper fringe portion an apertured member having a penetrating opening sealed along the opening. An insulative outer frame having a thermal expansion coefficient of the same order as that of the apertured member is supported on the peripheral portion of the apertured member. A lid member for hermetic sealing is bonded onto the outer frame.
