摘要:
The embodiments describe systems and methods for combinatorial processing of a substrate. In some embodiments, chemical mechanical polishing (CMP) techniques are combinatorially processed and evaluated. The CMP system is capable of providing a localized planarization surface to at least a region of a substrate being combinatorially processed. In some embodiments, the CMP system comprises a reactor assembly having plurality of reaction chambers, with at least a reaction chamber comprising a rotatable polishing head, slurry and chemical distribution, chemical and water rinse, and slurry and fluid removal. Accordingly, from a single substrate, a variety of materials, process conditions, and process sequences may be evaluated for desired planarization results.

An automatic loader of abrasive sand into a storage and supply tank (T) of a machine tool that uses the abrasive sand, and in particular of a cutting machine, includes a loading chamber (1) for loading the abrasive sand arranged above the supply opening of the tank (T) and having a suction inlet, connected through an air suction pipe (6) to a vacuum pump (2), and a sand inlet, in a lower position, connected through a sand suction pipe (7) to a supply container (S) for abrasive sand. A filter (F) is arranged inside the loading chamber (1), between the suction inlet and the sand inlet, and the loading chamber (1) is closed below by a butterfly valve (9) provided with spring element apt to retain the valve in the closed position when there is no sand inside the loading chamber (1).

A supply wax structure of a reel for a polisher includes a protective layer on one surface; a releasable layer on the other surface; and a wax layer adhered between the protective layer and the releasable layer. In one embodiment, the protective layer has a plurality of first apertures arranged in rows filled with wax and the releasable layer has a plurality of second apertures arranged in rows filled with wax. Preferably, the releasable layer is formed of fabric. Preferably, the protective layer is formed of paper. Preferably, the width of the wax layer is substantially equal to that of a polishing wheel of the polisher.
摘要:
A polishing pad for use in chemically mechanically polishing a semiconductor substrate enhances the uniformity of the rate at which material is removed from the surface of the semiconductor substrate, thereby ensuring the reproducibility of the chemical mechanical polishing process. The polishing pad has main grooves that divide an upper portion of the pad into a plurality of cells. At least one of the cells includes a land portion and a grooved portion substantially enclosed by the land portion. A respective slurry hole extends through the pad to the grooved portion such that slurry supplied through the slurry hole feeds into the grooved portion but is impeded by the land portion from flowing outwardly of the cell.

A pressurized delivery system for abrasive particulate material includes a storage container adapted to contain the abrasive particulate material therein, an input pressure line adapted to communicate with a pressurized source, and a fluidizing pressure line communicating with the input pressure line and an inlet opening in the storage container. A back-pressure pressure line communicates with an unoccupied portion of the storage container and an output pressure line. The output pressure line, into which the abrasive particulate material is fed from the storage container, communicates with the input pressure line, the back-pressure pressure line, and an outlet opening of storage container. During operation, pressurized gas is released through the inlet opening and into the storage container such that the abrasive particulate material adjacent the outlet opening is fluidized and maintained flowable so as to achieve consistent flow of the abrasive particulate material through the outlet opening.
