IPC: H01L23/48
Filed: 1984-05-16
Abstract: PURPOSE:To obtain a material having high thermal and electrical conductivities and also having a coefficient of thermal expansion similar to that of ceramics or glass, by compositing a material having high thermal and electrical conductivities with a material having a properly leveled coefficient of thermal expansion. CONSTITUTION:A plate 12 of sealing alloy having a coefficient of thermal expansion of (50-90)X10<-7>/ deg.C(30-450 deg.C) is bonded on at least one surface of a plate 11 of copper or copper alloy having an electrical conductivity of 14% IACA or more. Alternatively, the plate 11 of copper or copper alloy having an electrical conductivity of 14% IACA or more may be bonded to at least one edge of the plate 12 of sealing alloy having a coefficient of thermal expansion of (50-90)X10<-7>/ deg.C(30-450 deg.C). Since the copper or copper alloy having an electrical conductivity of 14% IACA or more also has a high thermal conductivity, it accelerates the heat dissipasion from the IC chip, while the sealing alloy having a thermal expansion coefficient of (50-90)X10<-7>/ deg.C serves of maintaining a good bonding relation with a sealing material of glass or ceramics. Thus, both requirements of high heat conductivity and suitable expansion are satisfied simultaneously.
