Abstract
A device for generating a security key includes a substrate, semiconductor units, contact structures, and defects. The semiconductor units are disposed on the substrate. The contact structures are disposed on and connected with the semiconductor units. The defects are disposed in at least a part of the contact structures randomly. A manufacturing method of a device for generating a security key includes the following steps. First semiconductor units are formed on a substrate. First contact structures are formed on the first semiconductor units. The first contact structures are connected with the first semiconductor units, and defects are formed in at least a part of the first contact structures randomly.
