  • Publication number: 20070155178
    Abstract: A slurry composition useful for chemical mechanical polishing of the surface of a material layer, e.g., a silicon oxide layer, is disclosed. A first material surface which is exposed to the slurry exhibits hydrophilicity, while a second material layer, e.g., a polysilicon layer, the surface of which is also exposed to the slurry, exhibits hydrophobicity, and accordingly acts as a polishing stopping layer. The slurry composition consists essentially of water, abrasive grains, and a polymer additive having both hydrophilic and hydrophobic functional groups.

  • Publication number: 20070117378
    Abstract: A method for use in manufacturing a semiconductor device includes forming a photoresist pattern on a substrate, performing first etching process in which an initial trench is formed using the photoresist pattern as a mask, and performing second distinct etching process to enlarge the initial trench. Thus, the initial trench can be formed using the photoresist pattern having a stable structure. Thereafter, the trench is enlarged using an etching solution having a composition based on the material in which the initial trench is formed, e.g., silicon substrate or an insulation film. Therefore, a metal wiring, an isolation film or a contact can be formed in the enlarged trench to desired dimensions.

  • Patent number: 7153370
    Abstract: The present application discloses a method of cleaning a semiconductor wafer by mounting a wafer to a chuck, positioning a gas guard, defining therein a chamber having an open bottom, immediately above the layer of water, spraying de-ionized water onto the wafer while rotating the chuck at a location outside the chamber when the wafer is mounted to the chuck, to thereby form a layer of water on the wafer, and spraying a cleaning gas from a gas spraying unit disposed above said chuck through the chamber and into the layer of water to thereby cause the cleaning gas to dissolve in the layer of water, and at the same time moving the chamber across a surface of the wafer, to thereby clean the wafer, wherein said gas spraying unit includes a gas injection tube oriented to inject the cleaning gas towards the wafer mounted to the chuck, and the gas guard connected to the gas injection tube.

  • Patent number: 7144815
    Abstract: A polishing slurry including an abrasive, deionized water, a pH controlling agent, and polyethylene imine, can control the removal rates of a silicon oxide layer and a silicon nitride layer which are simultaneously exposed during chemical mechanical polishing (CMP) of a conductive layer. A relative ratio of the removal rate of the silicon oxide layer to that of the silicon nitride layer can be controlled by controlling an amount of the choline derivative.

  • Publication number: 20060270228
    Abstract: A method of forming a metal pattern using a selective electroplating process is provided. First, a dielectric layer is formed on an underlying layer. Then, a trench defining blanket region is formed by patterning the dielectric layer. A diffusion barrier layer is conformally formed in the trench and on the blanket region. A polishing/plating stop layer and an upper seed layer are conformally formed on the diffusion barrier layer in a successive manner. The polishing/plating layer in the blanket region is exposed by selectively removing the upper seed layer in the blanket region, and, at the same time, a seed layer pattern remaining in the trenches is formed. An upper conductive layer is formed to fill the trench surrounded by the seed layer pattern using an electroplating process. Then, the dielectric layer in the blanket region is exposed by planarizing the upper conductive layer, the polishing/plating stop layer, the seed layer pattern, and the diffusion barrier layer.
