An artificial fingerprint device (AFD) module using poly-Si thinfilm transistors with logic LSI compatible process for built-in security

摘要

An artificial fingerprint device module using polycrystallinesilicon thin film transistors with logic LSI compatible process isproposed for securing a digital society. Substituting for actualfingerprint characteristics variation of polysilicon thin filmtransistors is utilized. The variation is random and offers unique,nonalterable, and nonduplicable numbers. Stable recognition operationbased on the nature of polysilicon TFTs is suggested
