Description

Semiconductor equipment Cleaning of Parts platform

[technical field]

The utility model relates to a kind of semiconductor equipment Cleaning of Parts platform, particularly relate to a kind of relate to can be used for clean semiconductor equipment Cleaning of Parts platform.

[background technology]

In manufacture of semiconductor, must regularly or aperiodically to the part of semi-conductor processing equipment clean and regenerate, to maintain the usefulness of semi-conductor processing equipment, and can service life of extension device.

For physical vapour deposition (PVD) processing procedure, physical vapour deposition (PVD) processing procedure mainly deposits a film on a substrate.First utilize a dc source to be electrically coupled to a backboard and respectively and cover plate, cover plate by this backboard and this and in this reactor chamber, form electric field ion gun bundle is hit to metal targets.After ion gun bundle clashes into target, the metal sputtering on this target can be formed this film on the substrate.

Usually, the reactor chamber of physical vapour deposition (PVD) in use for some time, this the surface formation metal coating of plate and mother metal can be covered in reactor chamber, therefore must carry out cleaning and regenerate to reactor chamber, prevent metal coating from breaking or peel off the micro dust particle that produces be disseminated to this substrate and affect yield.So-called cleaning means that this covers the suitable method of the material selection of the metal coating of plate and this mother metal and material is removed in reactor chamber, such as soak reactor chamber with acid or alkaline chemical solution, the metal coating separated and dissolved covering plate and mother metal surface will be formed at.So-called regeneration recovers this in the mode such as sandblasting and shaping again after referring to and cleaning and covers plate and the original profile of mother metal and surface characteristic.But above-mentioned clean and regeneration all can corrode with loss reactor chamber in cover the body thickness of plate and mother metal, cause shorten service life.

In addition, for the screw hole in reaction chamber, such as be locked in the screw hole between this mother metal, above-mentionedly soak reactor chamber with chemical solution, this covered to plate and this step such as mother metal sandblasting and shaping can make screw hole produce reaming phenomenon, therefore after repeatedly carrying out cleaning and regenerate, screw hole size and original size difference to some extent can be caused, cause screw hole and screw to combine time error excessive and make not good even cannot the continuation of locking function use.

Further, owing to clean etc. in process aforementioned, a large amount of acidity or the chemical solution of alkalescence must be used, soak and cover plate and mother metal, with dissolution of metals plated film, make it and cover plate and mother metal is separated.Due to a large amount of acidity or the chemical solution of alkalescence inevitably must be used, thus in the process cleaned, a large amount of clear water must be used to rinse the part of manufacture of semiconductor.
