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 1):
A semiconductor-mounting heat dissipation base plate comprising:\n 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; and a heat dissipation base fixed to the insulating substrate at a side opposite to the metal circuit layer across the insulating substrate and formed from aluminum, wherein a crystal grain diameter regulated region in which crystal grain diameter is regulated is provided in at least a part of a surface of the heat dissipation base or the metal circuit layer, and the average crystal grain diameter in the crystal grain diameter regulated region is smaller than an average crystal grain diameter in other regions of the metal circuit layer and the heat dissipation base.
