  • Publication number: 20130217199
    Abstract: The present invention discloses a method for fabricating a resistive memory, including: fabricating a bottom electrode over a substrate; partially oxidizing a metal of the bottom electrode through dry-oxygen oxidation or wet-oxygen oxidation to form a metal oxide with a thickness of 3 nm to 50 nm as a resistive material layer; finally fabricating a top electrode over the resistive material layer. The present invention omits a step of depositing a resistive material layer in a conventional method, so as to greatly reduce the process complexity. Meanwhile, a self alignment between the resistive material layer and the bottom electrode can be realized. A full isolation between devices may be ensured so as to obviate the parasite effects occurred in the conventional process methods. Meanwhile, the actual area and designed area of the device are ensured to be consistent.

  • Publication number: 20120289004
    Abstract: The present invention discloses a fabrication method of a Ge-based N-type Schottky field effect transistor and relates to a filed of ultra-large-scaled integrated circuit fabrication process. The present invention forms a thin high K dielectric layer between a substrate and a metal source/drain. The thin layer on one hand may block the electron wave function of metal from inducing an MIGS interface state in the semiconductor forbidden band, on the other hand may passivate the dangling bonds at the interface of Ge. Meanwhile, since the insulating dielectric layer has a very thin thickness, and electrons can substantially pass freely, the parasitic resistances of the source and the drain are not significantly increased. The method can weaken the Fermi level pinning effect, cause the Fermi energy level close to the position of the conduction band of Ge and lower the electron barrier, thereby increasing the current switching ratio of the Ge-based Schottky transistor and improve the performance of the NMOS device.
