COPPER PLATING BATHS

US 6709564 (Rockwell Scient Licensing LLC) Brongo, M.; Dornisch, D. et al. The acid copper sulfate solutions used for e lec t ropla t ing copper circuitry in trenches and vias in IC dielectr ic ma te r i a l in the Damascene process are replaced with a type of plate system based on the use of highly complexing anions (e.g., pyrophospha te , cyanide, sulfamate, etc.) to provide an inherent ly high overvolt- age tha t effect ively suppres ses runaway copper deposition. Such

systems, requiring only one easily-controlled organic additive species to provide outstanding lev- eling, are more efficacious for bottom-up filling of Damascene trenches and vias than acid copper sulfate baths, which require a minimum of two organic additive species. The highly complexed baths produce fine-grained copper deposits that are typi- cally much harder than large-grained acid sulfate copper deposits, and which exhibit stable mechanical properties that do not change with time, there- by minimizing "dishing" and giving more consis- tent CMP results. The mechanical properties and

Continuously Remove Copper from Your Nickel Bath with the Dummycell T M

Our new Dummycell TM can sit on the bottom of your nickel tank and continuously remove copper while you plate with no nickel co-plate. The Dummycell T M will keep your bath to less than 2 ppm copper and you do nothing.*

Forget about after-hours maintenance, parts lost to poor quality, expensive additives that are just a band-aid. Give your main rectifier a break. Try the Dummycell T M

for thirty days with no obligation. Call (201) 944-8053 today to find out how.

tion of a reducing agent in an electroless bath for plating a first metal is de termined from the effect of the reducing agent on the electrodeposition rate of a second metal. For electroless cobalt and nickel baths, a sample of the electroless plat ing ba th is added to an acid copper plat ing solution and the copper electrodeposition rate is measured by cyclic voltam- metric stripping (CVS) analysis. Separate analyses for hypophos- phite and dimethylamineborane in baths employing both reducing agents are at tained via selective decomposit ion of the dimethylamineborane in acidic solution.

CORROSION RESISTANCE OF

AUSTENIT IC STAINLESS STEELS

US 6709528 (ATI Properties Inc.) Polinski, R.E.; Fritz, J.D. et al. Method of enhancing the corrosion resistance of an austenitic steel includes removing material from at least a portion of a surface of the steel such that corrosion initiation sites are eliminated or are reduced in number relative to the number resulting from processing in a conventional manner. Material may be removed from the portion by any suitable method, including, for example, grit blasting, grinding and/or acid pickling under condi- tions more aggressive than those in conventional processing of the same steel and constitutes a form of passivation.

US 6709505 (Gage Prod. Co.) Saqi:~et, X.G.; Summerfield, S. et al. Universal paint solvent comprises, on a weight basis, 1-30% of an acidic material selected from the group consisting of sulfonic acids, phosphonic acids, phosphoric acids, and combinations thereof, togeth- er with 10-80% of an organic solvent selected from the group consisting of alcohols, ethers, ketones, aldehydes, esters, and combinations thereof. In particular compositions, the acidic component is com- prised of a mixture of two different acids. Alkyl esters, part icularly acetate esters, are preferred organic solvents. Butyl acetate is a specially preferred solvent. The compositions solvate a large variety of different paint formulations, and are effective at room temperature. The compositions have particular utility for cleaning paint delivery systems and equipment.
