Abstract
PURPOSE: To connect pins or leads for an I/O terminal to a metal pad by Ag-Cu brazing material by forming the pad to be brazed in a thin film made of heat resistant metal, and associating metal having excellent bondability to ceramics or excellent wettability to the Ag-Cu brazing material.
CONSTITUTION: An Ag conductor 15 is contained in a ceramic substrate 1, and an Si chip 7, and Au electrodes 6 are placed on the upper face. The conductor 15 contained therein and through hole 16 is connected to kover pins 5 as I/O terminal by a thin Ti-Mo-Cu film 3 and further Ag-Cu brazing material 4 on the lower face. The thin film 3 is selected from group 4A, 5A, 6A, 8, 1B element metals of The Periodic Table and combination thereof as a metal layer. That is, a Ti layer 9 is to obtain adherence to the ceramics 1, an Mo layer 10 is to prevent the layer 9 from diffusing in Cn-Ag 3 brazing material, and a Cn layer 11 is to obtain wettability to the Ag-Cu brazing layer 4. Thus, brazing pin and leads having strong bonding strength can be inexpensively obtained.
