Description
Technical field
The present invention is on a kind of grinding positioning ring for semiconductor wafer chemical machinery, espespecially a kind of grinding positioning ring that grinding process operations are positioned for wafer.
Background technology
Press, the structure for the grinding positioning ring that general grinding wafer process operations are used, in the past with made by integrally formed material, after have consideration base portion ring body with grinding ring body respectively have its function, therefore have and develop heterogeneous (different material) as the construction of composite bed, the construction presented such as TaiWan, China new patent No. M347978 " structure-improved of grinding positioning ring ", one base portion, it is adopted as made by stainless steel or metal alloy, and in an annular aspect, the first side of the base portion is to be provided with positioning hole on a locking face, locking face;The second side of base portion is to be provided with engaging hole on a faying face, faying face, and the engaging hole, which can be used to connect, sets locking conjugative component.One grind section, it is adopted as made by macromolecule plastic material, and in an annular aspect, the first side of the grind section is to be provided with entrance hole on a faying face, faying face;The second side of grind section is then an abradant surface.
It is combined with each other and is constituted with the grinding ring body of a macromolecule material by the base portion ring body of metal, different effects is showed respectively.But the prior art " heterogeneous " that is showed using base material be the higher stainless steel or metal alloy of usual hardness, but grind section, then using the relatively low macromolecule plastic material of relative hardness.
Though the case emphasis is found expression in response to grinding positioning ring during attrition process, the violent rubbing action of continuation is produced between meeting and wafer and processing parts, reversal of stress produced by it, then can be to the integrated structure of the base portion ring body of grinding positioning ring and grinding ring body, produce destructive effects, and the base portion of prior art its adopt as made by stainless steel or metal alloy, its material is bought and manufacturing cost is higher, and heavier-weight and easy-to-rust, and the combination of metal material and plastic material using above easily cause peel off so that causing wafer scratch, the yield after grinding wafer is caused to reduce, and processing cost is significantly increased, and manufacturing procedure is complicated, the bond strength that metal material is combined with plastic material again is weaker, its toughness is also relatively low with compliance, easily cause the phenomenon of stripping, that is, the equivalent grinding positioning ring is scrapped.So as to the loss more seriously cost increase, and more difficult lifting crudy of material.
Although, also dealer uses plastics (such as PPS) to be formed in one for a base portion with a grind section, though production cost can be reduced without using metal, but due to being one, therefore when grind section is worn and consumed, even if the base portion is without attrition, but also must integrally it be changed in company with the grind section, but because plastics (PPS) expense is immeasurable, also fall within waste with it is uneconomical.
The content of the invention
The problem of in view of prior art, inventor appreciates that there should be a kind of improved construction to produce, a kind of grinding positioning ring for semiconductor wafer chemical mechanical polishing process is designed for this, including one locks face and an abradant surface, both sequentially fold and merge into combination, the two composite bed effect having concurrently.
The present invention takes this to lock face selected from proportion 0.9-1.8g/cm3Between PET and high density polyethylene (HDPE) (High-density polyethylene, HDPE), polyethylene (Polyethylene, PE), polyphenylene sulfide (polyphenylene
Sulfide, PPS), polybutylene terepthatlate (polybutylene
Terephthalate, PBT), carbon fill polyether-ether-ketone (carbin-filled
PEEK), PEI (polyetherimide, PEI), polyether-ether-ketone (polyether ether ketone, PEEK), polyethylene terephthalate (polyethylene terephthalate, PET), polytetrafluoroethylene (PTFE) (polytetrafluoroethylene, PTFE), polybenzimidazoles (polybenzimidazole, PBI), polyamine-acid imide (polyamide-imide, PAI), polyethylene terephalic acid fat (PETP), polyvinyl chloride (PVC), nylon (NYLON), polyacetals (POM), ABS, iron is not imperial (PTFE), the one of poly- vinylidene fluoride PVDF or more than two kind it is compound.Or more than two kinds of any plastics additive is combined.Only, take off the plastics additive before not limiting, it is all with it is of the invention before take off the plastic material for having equivalent effect and all belong to and include.
The present invention locks face using foregoing plastic material at this, this is locked face because material selection is different so that whole grinding positioning ring has the progressive features such as weight saving, intensity are good, cost is reduced, reduce process, reduction is got rusty.
And the present invention is divided into one and locks face and an abradant surface, therefore when the abradant surface is worn and when consuming, this locks face and need not integrally changed in company with the abradant surface, therefore can save consumption and reach reduction cost effectiveness.
