Abstract
An artificial fingerprint device module using poly-crystalline silicon thin film transistors with logic LSI compatible process is proposed for securing a digital society. Substituting for actual fingerprint, characteristics variation of poly-silicon thin film transistors is utilized. The variation is random and offers unique, non-alterable, and non-duplicable numbers. Stable recognition operation based on the nature of poly-silicon TFTs is suggested.
