    摘要: Sub-micron dimensioned, ultra-shallow junction MOS and/or CMOS transistor devices having reduced or minimal junction leakage are formed by a salicide process wherein carbonaceous residue on silicon substrate surfaces resulting from reactive plasma etching for sidewall spacer formation is removed prior to salicide processing. Embodiments include removing carbonaceous residues by performing a hydrogen ion plasma treatment.

    摘要: In a method for forming an interlayer dielectric (ILD) coating on microcircuit interconnect lines of a substrate, a SiON layer is formed by using plasma-enhanced chemical vapor deposition. The deposition using a plasma formed of nitrogen, nitrous oxide, and silane gases, with the gases being dispensed at regulated flow rates and being energized by a radio frequency power source. The plasma reacts to form SiON which is deposited on a semiconductor substrate. During deposition, silane flow rates are regulating and reducing to less than sixty standard cubic centimeters per minute, thereby reducing the incidence of stress-induced voiding in the underlying interconnect lines. During deposition adjustments are made in deposition temperature and process pressure to control the characteristics of the SiON layer. The SiON layer is tested for acceptable optical properties and acceptable SiON layers are coated with a SiO2 layer to complete formation of the ILD. Once the ILD is formed the substrate is in readiness for further processing.

    摘要: A method for making 0.25 micron semiconductor chips includes using TEOS as the high density plasma (HDP) inter-layer dielectric (ILD). More specifically, after establishing a predetermined aluminum line pattern on a substrate, TEOS is deposited and simultaneously with the TEOS deposition, excess TEOS is etched away, thereby avoiding hydrogen embrittlement of and subsequent void formation in the aluminum lines that could otherwise occur if silane were used as the HDP ILD.

    摘要: A semiconductor component having a titanium silicide contact structure and a method for manufacturing the semiconductor component. A layer of dielectric material is formed over a semiconductor substrate. An opening having sidewalls is formed in the dielectric layer and exposes a portion of the semiconductor substrate. Titanium silicide is disposed on the dielectric layer, sidewalls, and the exposed portion of the semiconductor substrate. The titanium silicide may be formed by disposing titanium on the dielectric layer, sidewalls, and exposed portion of the semiconductor substrate and reacting the titanium with silane. Alternatively, the titanium silicide may be sputter deposited. A layer of titanium nitride is formed on the titanium silicide. A layer of tungsten is formed on the titanium nitride. The tungsten, titanium nitride, and titanium silicide are polished to form the contact structures.

    摘要: A method for forming an interconnect structure includes forming a recess in a dielectric layer of a substrate. An adhesion barrier layer is formed to line the recess. A first stress level is present across a first interface between the adhesion barrier layer and the dielectric layer. A stress-reducing barrier layer is formed over the adhesion barrier layer. The stress-reducing barrier layer reduces the first stress level to provide a second stress level, less than the first stress level, across a second interface between the adhesion barrier layer, the stress-reducing barrier layer, and the dielectric layer. The recess is filled with a fill layer.

    摘要: Transistor devices are formed with nickel silicide layers formulated to prevent degradation upon removal of overlying stress liners. Embodiments include transistors with nickel silicide layers having a platinum composition gradient increasing in platinum content toward the upper surfaces thereof, i.e., increasing in platinum in a direction away from the gate electrode and source/drain regions. Embodiments include forming a first layer of nickel having a first amount of platinum and forming, on the first layer of nickel, a second layer of nickel having a second amount of platinum, the second weight percent of platinum being greater than the first weight percent. The layers of nickel are then annealed to form a nickel silicide layer having the platinum composition gradient increasing in platinum toward the upper surface. The platinum concentration gradient protects the nickel silicide layer during subsequent processing, as during etching to remove overlying stress liners, thereby avoiding a decrease in device performance.
