    摘要: A polycide gate structure and a method of forming the polycide gate. A substrate having a gate dielectric layer, a polysilicon layer, a silicide layer and an insulation layer thereon is provided. The polysilicon layer is above the gate dielectric layer, the silicide layer is above the polysilicon layer, and the insulation layer is above the silicide layer. A patterned photoresist layer is formed over the insulation layer. Using the photoresist layer as a mask, an anisotropic etching operation is carried out to remove the exposed insulation layer. Again using the photoresist layer as a mask, a first type of plasma is used to carry out a first anisotropic etching operation to remove the exposed silicide layer. A metallic oxide layer is formed on the sidewalls of the silicide layer by the oxidation of a portion of the retained silicide layer. Using the photoresist layer as a mask, a second type of plasma is used to carry out a second anisotropic etching operation to remove the exposed polysilicon layer. The metallic oxide layer is resistant to attack by the second type of plasma.

    摘要: First, a substrate with a recess is provided in a semiconductor process. Second, an embedded SiGe layer is formed in the substrate. The embedded SiGe layer includes an epitaxial SiGe material which fills up the recess. Then, a pre-amorphization implant (PAI) procedure is carried out on the embedded SiGe layer to form an amorphous region. Next, a source/drain implanting procedure is carried out on the embedded SiGe layer to form a source doping region and a drain doping region. Later, a source/drain annealing procedure is carried out to form a source and a drain in the substrate. At least one of the pre-amorphization implant procedure and the source/drain implanting procedure is carried out in a cryogenic procedure below −30° C.

    摘要: In one embodiment, a via structure includes a liner, a barrier layer over the liner, and an aluminum layer over the barrier layer. The barrier layer helps minimize reaction between the aluminum layer and the liner, thus helping minimize void formation in the via. The liner and the barrier layer may be deposited in-situ by ionized metal plasma (IMP) physical vapor deposition (PVD). In one embodiment, the liner comprises titanium, while the barrier layer comprises titanium nitride.
