Physical unclonable function system and manufacturing method for physical unclonable function device

Abstract

A system of a physically unclonable function includes a logic circuit, and a physically unclonable function device. The physically unclonable function device includes a substrate, a via layer, and a pattern layer. The substrate includes at least one transistor. The via layer includes vias, in which the vias are disposed on the at least one transistor and arranged in an array. The pattern layer is disposed on the via layer and includes at least one conductive area. First vias of the vias overlap the at least one conductive area, and the first vias output signals from the transistor to the logic circuit through the conductive area.
