Semiconductor device and method for manufacturing the same

A method for manufacturing semiconductor devices comprising:

• a step of filling a mixture containing metal particles and polymers in a guide;
• and
• a step of subjecting the mixture to a heat treatment so that the polymers agglomerate to the guide to form a polymer layer that makes contact with the guide and the metal particles agglomerate away from the guide with the polymer layer interposed therebetween to form a metal column that stretches in a stretching direction of the guide from the metal particles, wherein
• the guide is hydrophilic, and
• the polymers include at least hydrophilic polymers.
