    摘要: The present invention discloses the single gate CMOS with the surface channel manufactured according to the manufacturing method of the present invention is very advantageous for improving the characteristics, yield and reliability of the device, by performing decoupled plasma nitridation (DPN) process on the gate oxide film of the cell NMOS and the peripheral PMOS, respectively, thereby forming a silicon nitride on the surface of the gate oxide film. Further, the single gate CMOS with the surface channel can be formed more easily through the simplified process in overall, without requiring a separate transient ion implantation process, even when the gate electrode of the n+ polysilicon layer is used, by having the threshold voltage of the cell NMOS be approximately +0.9V, the threshold voltage of the peripheral PMOS be approximately −0.5V and above, and the threshold voltage of the peripheral NMOS be approximately +0.5V and below. In addition, since the cell NMOS already has +0.9V of threshold voltage, back bias does not have to be applied separately to achieve the +0.9V threshold voltage, and the device with low power consumption is formed successfully.

    摘要: A method for forming a metal gate capable of preventing degradation in a characteristic of a gate insulating film upon formation of the metal gate. The method of forming the metal gate comprises the steps of providing a silicon substrate having device isolation films of a trench shape for defining an active region; forming a gate insulating film on the surface of the silicon substrate by means of a thermal oxidization process; sequentially forming a barrier metal film and a metal film for the gate on the gate insulating film; and patterning the metal film for the gate, the barrier metal film and the gate insulating film, wherein deposition of the barrier metal film and the metal film for the gate is performed by means of an atomic layer deposition (ALD) process or remote plasma chemical vapor deposition (CVD) process.

    摘要: Disclosed are a semiconductor devices and method of fabricating the same. Anti-etch films are formed in the top corners of the device isolation film using a material that has a different etch selectivity ratio from nitride or oxide and is not etched in an oxide gate pre-cleaning process. It is thus possible to prevent formation of a moat at the top corners of the device isolation film and the gate oxide film from being thinly formed, thereby improving reliability and electrical characteristics of the device.
