Connecting structure for electronic part and method of manufacturing the same

摘要

Disclosed is a connecting structure for electrically connecting an electronic part such as an LSI chip to a substrate and a method of manufacturing the same. The present invention is suitable especially for electrical connection between a plurality of chips and a substrate which is required to have a function of absorbing a difference in thermal expansion in the horizontal direction and to deform in the vertical direction, and characterized in that a conductive flat spring having a height not more than the minimum length in the lateral direction is provided between the electronic part such as a chip and a wires substrate.
