  • 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).

  • Patent number: 9312357
    Abstract: A semiconductor device and a method for manufacturing the same. The method includes steps hereinafter. A substrate is provided with a first dielectric layer thereon. The first dielectric layer is provided with a trench. Then, a metal layer is formed to fill the trench and to cover the surface of the first dielectric layer. The metal layer is partially removed so that a remaining portion of the metal layer covers the first dielectric layer. A treatment process is performed to transform the remaining portion of the metal layer into a passivation layer on the top portion and a gate metal layer on the bottom portion. A chemical-mechanical polishing process is performed until the first dielectric layer is exposed so that a remaining portion of the passivation layer remains in the trench.
