  • Publication number: 20250017003
    Abstract: A method for physically unclonable function through gate height tuning is provided in the present invention, including steps of forming a high-k dielectric layer and a dummy silicon layer on a semiconductor substrate, removing the dummy silicon layer, forming a work function layer and a metal filling layer on the high-k dielectric layer, and performing a CMP process to remove the metal filling layer, so as to form metal gates with heights lower than a critical gate height, and using the metal gates to manufacture PIO pairs in an internal bias generator. Since the height of metal gates is lower than the critical gate height, a local threshold voltage mismatching of the programmed I/O (PIO) pairs becomes larger, so as to achieve random code generation in physically unclonable function (PUF).
