  • Publication number: 20090186475
    Abstract: A method of manufacturing a MOS transistor, in which, a tri-layer photo resist layer is used to form a patterned hard mask layer having a sound shape and a small size, and the patterned hard mask layer is used to form a gate. Thereafter, by forming and defining a cap layer, a recess is formed through etching in the substrate. The patterned hard mask is removed after epitaxial layers are formed in the recesses. Accordingly, a conventional poly bump issue and an STI oxide loss issue leading to contact bridge can be avoided.

  • Publication number: 20090137089
    Abstract: A method of manufacturing a metal-oxide-semiconductor (MOS) transistor device is disclosed. A gate dielectric layer is formed on an active area of a substrate. A gate electrode is patterned on the gate dielectric layer. The gate electrode has vertical sidewalls and a top surface. A liner is formed on the vertical sidewalls of the gate electrode. A nitride spacer is formed on the liner. An ion implanted is performed to form a source/drain region. After salicide process, an STI region that isolates the active area is recessed, thereby forming a step height at interface between the active area and the STI region. The nitride spacer is removed. A nitride cap layer that borders the liner is deposited. The nitride cap layer has a specific stress status.

  • Publication number: 20090117701
    Abstract: A method for manufacturing a MOS transistor includes performing a thermal treatment to repair damaged substrate before forming source/drain extension regions, accordingly negative bias temperature instability (NBTI) is reduced. Since the thermal treatment is performed before forming the source/drain extension regions, heat budget for forming the source/drain extension regions and junction depth and junction profile of the source/drain extension would not be affected. Therefore the provided method for manufacturing a MOS transistor is capable of reducing short channel effect and possesses a superior process compatibility.

  • Publication number: 20080311699
    Abstract: A phase-change memory comprises a bottom electrode formed on a substrate. A first isolation layer is formed on the bottom electrode. A top electrode is formed on the isolation layer. A first phase-change material is formed in the first isolation layer, wherein the top electrode and the bottom electrode are electrically connected via the first phase-change material. Since the phase-change material can have a diameter less than the resolution limit of the photolithography process, an operating current for a state conversion of the phase-change material pattern may be reduced so as to decrease a power dissipation of the phase-change memory device.
