Bonded body of ceramic member and metal member and method for manufacturing the same

A bonded body 10 includes a plate-shaped alumina or aluminum nitride ceramic member 12 and a Mo or Ti terminal 14 having a Ni coating, a Au coating, or a Ni-Au coating (Au on Ni) and joined to a recess 12a in the ceramic member 12 with a joint layer 16 therebetween. The joint layer 16 contains Au, G...

Beschreibung
Zusammenfassung:	A bonded body 10 includes a plate-shaped alumina or aluminum nitride ceramic member 12 and a Mo or Ti terminal 14 having a Ni coating, a Au coating, or a Ni-Au coating (Au on Ni) and joined to a recess 12a in the ceramic member 12 with a joint layer 16 therebetween. The joint layer 16 contains Au, Ge, Ag, Cu, and Ti and is in contact with at least part of the side surfaces (herein the entire side surfaces) and the bottom surface of the recess 12a. Ti is rich in the joint interface between the joint layer 16 and the ceramic member 12. The percentage (porosity) of the sum of the cross-sectional areas of pores to the cross-sectional area of the joint layer 16 in a cross-section taken across the thickness of the bonded body 10 is 0.1% to 15%.
