The present invention relates to a semiconductor device and a method for manufacturing the same that prevent deformation or cracking caused by a difference in coefficient of thermal expansion. Elastic contacts provided on upper and lower surfaces of an interposer are elastically biased against the relatively displaced electrodes. The interposer thus compensates for displacement caused by different coefficients of thermal expansion so that an electrical connection between the electrodes of the first electronic component and the electrodes of the second electronic component is constantly maintained. Accordingly, this prevents separation or cracking in electrode connection areas.
