    摘要: A management system and method of a reticle in an exposing process are disclosed. A calculator calculates an accumulated dosage of an illuminating light irradiated onto a reticle used in a photolithography process. The calculator is connected to an exposing apparatus to expose photoresist on a semiconductor substrate. A comparator compares the calculated accumulated dosage with a preset reference dosage. When the calculated accumulated dosage is greater than or equal to the reference dosage, a controller suspends the photolithography process. Minimizing haze contamination on the reticle, thus preventing process failures.

    摘要: An air shower head of an exposure device of photolithography equipment is free of chemical substances that could otherwise contaminate a photoresist layer on a semiconductor wafer and degrade the profile of the photoresist pattern. The air shower head is interposed between a lens system of the exposure device and a wafer stage, and has a hole in the middle thereof through which exposure light can pass to a wafer supported on the stage. The air shower head includes an upper frame defining a cavity open at the bottom thereof, and a porous bottom member covering the bottom of the upper frame. The porous member is mechanically secured to bottom ends of both the inner and outer side walls of the upper frame, i.e., without the use of chemical binders, to reduce the ability of the air shower head to serve as a source of contamination.

    摘要: A chemical mechanical polishing (CMP) apparatus for planarizing the surface of a semiconductor wafer is provided with a washing unit including first, second and third nozzles installed within a load-cup where the loading and unloading of the wafers takes place. The first nozzles spray deionized water toward the top face of a pedestal on which the wafers are placed in the load cup, thereby washing contaminants off of the pedestal. The second nozzles spray deionized water toward a membrane provided at the bottom of a polishing head, thereby washing the membrane. The third nozzles spray deionized water through purge holes formed in a retainer ring of the polishing head toward a space formed between the outer surface of the membrane and the inner surface of the retainer ring. Consequently, contaminants induced into the space are washed away. The CMP apparatus also includes an exhaust unit having an outlet, an exhaust pump and an exhaust pipe connecting the outlet and the exhaust pump, for exhausting contaminants to the outside of the CMP apparatus through a protective cover thereof. The exhaust outlet is provided at the bottom of a side of the protective cover.
