Abstract: The present invention relates to a photoresist stripper composition for manufacturing a display, and more particularly, to an integrated photoresist stripper composition which can be used in every process for manufacturing a display. More specifically, the photoresist stripper composition for manufacturing a display according to the present invention can be applied to all of transition metals and oxide semiconductor wirings, and has an excellent ability to remove modified photoresist after a hard bake process, and implant process, and a dry etch process have been performed. In particular, the photoresist stripper composition for manufacturing a display according to the present invention exhibits a corrosion inhibitory effect that has been further specialized for copper (Cu) wiring pattern edge portions which are susceptible to corrosion following dry-etching.

Abstract: An ion implanter which prevents undesired impurities from being implanted into a wafer has an ion source for producing an ion beam which is to be implanted into a wafer, an accelerator for accelerating the ion beam, and an impurity interceptor for intercepting impurities generated in the accelerator. The impurity interceptor has an intercepting plate electrically connected to a high voltage power supply, and an opening formed in the center of the plate. Undesired ions having an energy lower than the high voltage applied to the intercepting plate are intercepted, and only those desired ions having an energy higher than the high voltage applied to the intercepting plate pass through the opening.

Abstract: An apparatus for manufacturing a semiconductor device employs a vacuum system, in which a heating source is installed in a predetermined portion of a venting-gas inlet. A venting-speed controlling valve is installed in a predetermined portion of an exhaust pipe, for controlling the speed of gas flowing from a load lock chamber to a pump by controlling the opening and closing thereof. An exhaust pipe may have a main pipe with different diameters in different portions to reduce the venting speed. Accordingly, condensation-induced particle formation can be reduced by thus preventing adiabatic expansion of the gas in a load lock chamber.
