    摘要: Self-aligned silicide regions (24) are formed in a semiconductor device (10) using vapor phase reaction. A chemical vapor deposition system (40) is used, but rather than depositing a blanket silicide material, a precursor (48) is introduced into the reaction chamber (42) and reacts with only exposed silicon and polysilicon members of the device. The reaction is assisted by heating the substrate to a temperature at which the precursor is volatile. Because the precursor source reacts only with exposed silicon and polysilicon regions, subsequent etch steps are unnecessary. In one form, cobalt silicide regions are formed using a cobalt carbonyl as the precursor source.

    摘要: Methods and apparatus are provided for depositing a layer of pure germanium can on a silicon substrate. This germanium layer is very thin, on the order of about 14 Å, and is less than the critical thickness for pure germanium on silicon. The germanium layer serves as an intermediate layer between the silicon substrate and the high k gate layer, which is deposited on the germanium layer. The germanium layer helps to avoid the development of an oxide interfacial layer during the application of the high k material. Application of the germanium intermediate layer in a semiconductor structure results in a high k gate functionality without the drawbacks of series capacitance due to oxide impurities. The germanium layer further improves mobility.

    摘要: A method for forming vias in a semiconductor device improves the resistance and reliability of contacts formed by use of an etch stop layer during the via formation process. An etch stop layer (40), preferably a silicon nitride or aluminum nitride layer, is deposited over conductive interconnect (34). A via (44) is etched in interlayer dielectric (42), stopping on etch stop layer (40). Etch stop layer (40) is then anisotropicly etched to expose the top of conductive interconnect (34), while maintaining a portion of the etch stop layer along a sidewall of the interconnect, and particularly along those sidewall portions which contain aluminum. A conductive plug (54) is then formed in the via, preferably using one or more barrier or glue layers (50). Formation of a tungsten plug using tungsten hexafluoride can then be performed without unwanted reactions between the tungsten source gas and the aluminum interconnect.

    摘要: A trench isolation region (32) is fabricated to include a trench liner (28) comprised of aluminum nitride. The aluminum nitride trench liner is useful in borderless contact applications wherein a contact opening (56) is etched in an interlayer dielectric (54) and overlies both an active region. (e.g. doped region 52) and the trench isolation region. During formation of opening using etch chemistry which is selective to aluminum nitride, the trench liner protects a P-N junction at a corner region (58) of the trench to prevent exposing the junction. By protecting the junction, subsequent formation of a conductive plug (60) will not electrically short circuit the junction, and will keep diode leakage to within acceptable levels.

An opening is formed through the capacitor and extends to the circuit element. An insulating spacer is formed, and a conductive member is formed that electrically connects the circuit element to the upper electrode layer of the metal-oxide capacitor.

    摘要: The selection of pH, the polishing slurry, and types of polishing particles within a polishing slurry are chosen, so that polishing product is capable of coating onto the polishing particles. More specifically, the pH of the polishing slurry is selected to be between the iso-electric points of the polishing product and the particles within the polishing slurry. More than one type of material may be used within a polishing slurry. Particles of one material may do most of the polishing, while the particles of the other material become coated with polishing product and aid in transporting it away from the substrate.
