ELECTRONIC MEMBER, ELECTRONIC COMPONENT AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an electronic member which can supply joint material at a fine pitch, and can be electrically connected.

SOLUTION: To one or more connection terminals provided on a circuit substrate, one or more electrodes provided on an electronic member is electrically joined through a joint layer. The joint layer is configured by mainly sintered silver. The whole area or a part of an electrode surface which is not contacted with the joint layer is a roughening layer of silver oxide. The thickness of the roughening layer of the silver oxide is 400 nm to 5 μm, and the outermost surface of the layer of the silver oxide has a curvature radius smaller than 1 μm.
