  • Patent number: 7125802
    Abstract: Two problems seen in CMP as currently executed are a tendency for slurry particles to remain on the surface and the formation of a final layer of oxide. These problems have been solved by adding to the slurry a quantity of TMAH or TBAH. This has the effect of rendering the surface being polished hydrophobic. In that state a residual layer of oxide will not be left on the surface at the conclusion of CMP. Nor will many slurry abrasive particles remain cling to the freshly polished surface. Those that do are readily removed by a simple rinse or buffing. As an alternative, the CMP process may be performed in three stages—first convention CMP, then polishing in a solution of TMAH or TBAH, and finally a gentle rinse or buffing.

  • Patent number: 6584987
    Abstract: A method for cleaning residual material from a chemical vapor deposition (CVD) apparatus in situ employing dry etching. There is first employed a high density plasma chemical vapor deposition (HDP-CVD) method to deposit layers of silicon oxide material upon substrates within a chemical vapor deposition reactor apparatus. After removal of substrates, the reactor chamber is closed off. The interior of the reactor is then filled with a gas and a plasma formed therewithin, to which oxygen is added and the reactor allowed to come to an increased temperature and bake for a period of time. The reactor power is then turned off and the reactor evacuated. There is then carried out a normal cleaning step within the reactor chamber employing a reactive gas such as NF3, with greater cleaning efficiency due to the increased temperature caused by the baking step.

  • Patent number: 6558228
    Abstract: An improved and new process for separating a substrate from a wetted polishing pad in a CMP apparatus has been developed. Following CMP the polishing pad is wetted with a low surface tension liquid and the substrate is moved across the surface of the polishing pad to cause the interface between the substrate and the polishing pad to be wetted with the low surface tension liquid. The force required to cause separation of the substrate from the polishing pad wetted with said low surface tension liquid is reduced by a factor of about 10 to 30% and the breakage of fragile semiconductor wafer substrates during the unloading operation is markedly reduced. Suitable low surface tension liquids are water at a temperature between about 50° C. and 80° C., or solutions of water with long chain surfactants, such as poly-acrylate, poly-vinyl alcohol, butanol, pantanol or isopropol alcohol.

  • Patent number: 6499222
    Abstract: A template for measuring the edge width on a disk that is not covered by a coating layer on a top surface of the disk and a method for using such template are disclosed. The template is made of a substantially transparent sheet that has a contour substantially the same as the contour of the disk to be measured. A series of marks are provided on a top surface of the sheet along a peripheral edge of the sheet at numerous predetermined distances from the peripheral edge. The marks may be provided in scribed thin lines, or the marks may be provided in scribed thin lines that are color coded for easier identification purpose. The present invention novel template can be most suitably used on a silicon wafer of any size. However, it can also be used on a disk of any shape or contour to produce the same desirable result.

  • Patent number: 6323141
    Abstract: A method for forming a patterned reflective layer first employs a substrate. There is then formed over the substrate a blanket reflective layer. There is then formed upon the blanket reflective layer an anti-reflective coating (ARC) layer formed employing a plasma enhanced chemical vapor deposition (PECVD) method employing a deposition gas composition comprising silane, nitrous oxide and argon. There is then formed upon the blanket anti-reflective coating (ARC) layer a blanket photoresist layer. There is then photoexposed and developed the blanket photoresist layer to form a patterned photoresist layer. There is then etched, while employing a first etch method, the blanket anti-reflective coating (ARC) layer to form a patterned anti-reflective coating (ARC) layer while employing the patterned photoresist layer as a first etch mask layer.

  • Patent number: 6235653
    Abstract: A new method of forming a plasma-enhanced silicon-rich oxynitride layer having improved uniformity across the wafer in terms of layer thickness, refractivity, and reflectivity by using argon as the inert carrier gas is described. A semiconductor substrate is provided which may include semiconductor device structures. An Argon-based silicon-rich oxynitride etch stop layer is deposited overlying the semiconductor substrate. An oxide layer is deposited overlying the Argon-based silicon-rich oxynitride etch stop layer. An opening is etched through the oxide layer stopping at the Argon-based silicon-rich oxynitride etch stop layer. Thereafter, the Argon-based silicon-rich oxynitride etch stop layer within the opening is removed. The opening is filled with a conducting layer. This Argon-based silicon-rich oxynitride layer has improved uniformity across the wafer in terms of layer thickness, refractivity, and reflectivity as compared with a helium-based silicon-rich oxynitride layer.

  • Patent number: 6136680
    Abstract: A method of forming an interconnect, comprising the following steps. A semiconductor structure is provided that has an exposed first metal contact and a dielectric layer formed thereover. An FSG layer having a predetermined thickness is then formed over the dielectric layer. A trench, having a predetermined width, is formed within the FSG layer and the dielectric layer exposing the first metal contact. A barrier layer, having a predetermined thickness, may be formed over the FSG layer and lining the trench side walls and bottom. A metal, preferably copper, is then deposited on the barrier layer to form a copper layer, having a predetermined thickness, over said barrier layer covered FSG layer, filling the lined trench and blanket filling the barrier layer covered FSG layer. The copper layer, and the barrier layer on said upper surface of said FSG layer, are planarized, exposing the upper surface of the FSG layer and forming a planarized copper filled trench.
