The polishing head comprises a carrier having at least two fluid passages, a retainer ring disposed on a lower edge of the carrier, forming a space for receiving the wafer, a supporter disposed in the carrier, and a flexible membrane disposed to be in contact with the wafer. The supporter has an upper surface portion, a lower surface portion, a plurality of first holes, a plurality of second holes, and a first chamber. The upper surface portion of the supporter forms a second chamber along with an inner surface of the carrier. The second chamber is in communication with one of the two fluid passages of the carrier and the second holes are formed in a lower surface portion of the supporter to communicate with the second chamber. The first chamber is in communication with the other one of the two fluid passages and the first holes are formed in the lower surface portion of the supporter to communicate with the first chamber. The lower surface portion of the supporter has a flat surface and a chamfered or rounded edge. The membrane disposed to enclose the lower surface portion of the supporter has a plurality of third holes formed at positions corresponding to the first holes to absorb and hold the wafer by vacuum.

    摘要: A method for fabricating a MOS transistor using a selective silicide process wherein a gate insulating layer and a gate polysilicon layer are sequentially formed on a silicon substrate, and a gate spacer is formed on a side wall of the gate insulating layer and the gate polysilicon layer. Impurity ions are implanted and diffused using the gate spacer and the gate polysilicon layer as a mask layer to form a source/drain region in the substrate. An etching blocking layer is formed to cover the source/drain region, the gate spacer, and the gate polysilicon layer, and then, a dielectric layer to cover the etching blocking layer is formed. The dielectric layer is planarized, and the etching blocking layer on the gate polysilicon layer is exposed. The exposed etching blocking layer and a part of the gate spacer are etched, and a top surface and a top side of the gate polysilicon layer are exposed. A silicide layer is formed over the exposed part of the gate polysilicon layer.
