Abstract
A semiconductor device in which a silicon pellet is mounted on a ceramic substrate by means of a glass material of low melting point. To prevent the silicon pellet from being destroyed under thermal stress, the pellet is bonded to the glass material of low melting point through interposition of an adhesion reinforcing film such as an aluminium film capable of exhibiting a good wettability and a great bonding strength.
