Abstract:
Disclosed herein is a semiconductor wafer polishing apparatus having a magneto-rheological elastic pad, in which the dielectric layer of the wafer fixed in the wafer holder to contact the abrasive coated on a rotating plate is polished. The semiconductor wafer polishing apparatus comprises a magneto-rheological elastic pad formed by a plurality of segments received to be fixed on the rotating plate; a plurality of electromagnets, having equal or larger diameter than that of wafer to selectively pressurize a part or the entire area of the wafer, which is arranged at the lower portion of the rotating plate in such a way that the central part accords with the central axis of the wafer holder; and a controller for selectively generating the magnetic field at a part or the entire part of the electromagnets.
Abstract:
Provided are a method of manufacturing a polysilicon thin film transistor plate, which includes leveling the surface of crystallized polysilicon having protruding grains at grain boundaries to improve the electrical characteristics of an active layer, and a liquid crystal display including a polysilicon thin film transistor plate manufactured by the method. The method of manufacturing a polysilicon thin film transistor plate includes loading a substrate on which polysilicon grains are formed, removing protruding grains at grain boundaries among the polysilicon grains by chemical mechanical polishing (“CMP”) and forming a polished substrate, cleaning the polished substrate and forming a cleaned substrate, and unloading the cleaned substrate.
