Abstract:
In a semiconductor-mounting heat dissipation base plate including: an insulating substrate to which a metal circuit layer for mounting a semiconductor chip thereon is fixed; a heat dissipation base formed from the same metal material as the metal circuit layer at a side opposite to the metal circuit layer across the insulating substrate and fixed to the insulating substrate similar to the metal circuit layer; and a strengthening member provided in the heat dissipation base so as to be separated from the insulating substrate, the sizes of crystal grains of a metal structure at a part of the heat dissipation base or the metal circuit layer are reduced by a crystal size reducing material adhered to a mold, thereby preventing an adverse effect of a columnar crystal structure.

Claim (Index 8):
A method for producing a semiconductor-mounting heat dissipation base plate including: an insulating substrate which is formed from a ceramic and to which a metal circuit layer mounting a semiconductor component thereon and formed from aluminum is fixed by direct bonding through casting; and a heat dissipation base formed from aluminum and fixed to the insulating substrate at a side opposite to the metal circuit layer across the insulating substrate by direct bonding through casting, the method comprising\n adhering at least one or more types of a crystal grain size reducing material to a part of a cavity-side surface of a mold during casting of the heat dissipation base and the metal circuit layer, thereby forming a crystal grain diameter regulated region in which crystal grain diameter is regulated, in at least a part of a surface of the heat dissipation base or the metal circuit layer.
