Abstract
A method for fabricating a physically unclonable function (PUF) device includes the steps of first providing a PUF cell array having a plurality of unit cells, in which each of the unit cells includes a transistor and a first metal-oxide semiconductor capacitor (MOSCAP) and a second MOSCAP coupled to the transistor. Next, a voltage is transmitted through the transistor to the first MOSCAP and the second MOSCAP and whether the first MOSCAP or the second MOSCAP reaches a breakdown is determined.
