Feasibility of Physical Unclonable Functions from Pre-stressed Organic Thin Film Transistors for Secure Microelectronics Baghban-Bousari, N. Eric, Deborah Palau, Gerard Crespo Yepes, Albert Porti i Pujal, Marc Ramon, Eloi Ogier, S. Nafría i Maqueda, Montserrat OTFT PUF Reliability Uniformity Uniqueness Altres ajuts: acords transformatius de la UAB Pre-stressed commercial Organic Thin Film Transistors (OTFT) have been characterized to evaluate their suitability for Physical Unclonable Functions (PUFs) implementation, when the variability of the drain current (ID) is used as entropy source. Different kinds of electrical pre-stresses have been considered, to study their impact on the PUF reproducibility. Uniqueness and Uniformity of the resulting PUFs have also been evaluated. The proposed pre-stressed OTFTs based PUFs show a reproducibility up to 0.99, with a uniformity and uniqueness of 0.52 and 0.50, respectively. 2026 Article Agencia Estatal de Investigación PID2022-136949OB-C22 Agència de Gestió d'Ajuts Universitaris i de Recerca 2021/SGR-00199 Microelectronic engineering ; Vol. 302 (January 2026), art. 112407 open access Aquest document està subjecte a una llicència d'ús Creative Commons.
