<p><P>PROBLEM TO BE SOLVED: To provide a joined structure capable of preventing generation of cracks in a joined part and each joined object. <P>SOLUTION: Even when an AL substrate 1 is joined with a semi-conductor element 5 by using an AL brazing filler metal 4, an AL alloy 14 having the strength relatively close to that of the AL brazing filler metal 4 is provided on a joining surface 1a of the AL substrate 1. Thus, even when the temperature difference occurs between the AL substrate 1 and the semi-conductor element 5, any considerable difference in strength is not present between both members in a vicinity of a joined part of the AL brazing filler metal 4 with the AL substrate 1, an increase in distortion of each part is suppressed, and the reliability of the joined part is enhanced. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
