Method of Removing Metallic, Inorganic and Organic Contaminants From Chip Passivation Layer Surfaces
Publication number: 20100218894Abstract: A method of removing and/or reducing undesirable contaminants removes residues including graphitic layers, fluorinate layers, calcium sulfate (CaSO4) particles, tin oxides and organotin, from a chip passivation layer surface. The method uses a plasma process with an argon and oxygen mixture with optimized plasma parameters to remove both the graphitic and fluorinated layers and to reduce the level of the inorganic/tin oxides/organotin residue from an integrated circuit wafer while keeping the re-deposition of metallic compounds is negligible. This invention discloses the plasma processes that organics are not re-deposited from polymers to solder ball surfaces and tin oxide thickness does not increase on solder balls. The ratio of argon/oxygen is from about 50% to about 99% Ar and about 1% to about 50% O2 by volume. Incoming wafers, after treatment, are then diced to form individual chips that are employed to produce flip chip plastic ball grid array packages.Type: ApplicationFiled: May 14, 2010Publication date: September 2, 2010Inventors: Claude Blais, Eric Duchesne, Kang-Wook Lee, Sylvain Ouimet, Gerald J.

Patent number: 7780801Abstract: The invention relates to a composition of matter comprising a soldering flux, wherein the flux consists essentially of a combination of a fluxing agent and a solvent, and wherein the fluxing agent comprises a keto acid such as levulinic acid or acetylbutyric acid. The flux may also comprises an ester acid, or comprises a mixture of the keto acid with the ester acid. The solvent comprises a mixture of a tacky solvent with a non-tacky solvent. The invention also relates to a process comprising soldering at least two surfaces together, each of which comprises a metal area to which solder can adhere by employing the following steps in any order: applying solder to at least one of the metal areas, aligning the metal areas so that they are superimposed over one another, heating at least one of the areas to a temperature that comprises at least the melting temperature of the solder. The last step comprises joining the superimposed areas to one another.Type: GrantFiled: July 26, 2006Date of Patent: August 24, 2010Assignee: International Business Machines CorporationInventors: Eric Duchesne, Kang-Wook Lee, Valerie Oberson

Publication number: 20090298206Abstract: Utilizing an appropriately configured laser interferometer, the warpage of a silicon chip can be easily monitored during the solder reflow attachment process in an effort to determine the amount of stress encountered by the chip. Warpage measurements can then be continuously monitored throughout the process and related data can be stored to easily suggest the level of warpage generated by various processing parameters. By dynamically monitoring warpage in conjunction with processing parameters, a correlation can be established between the various parameters chosen, and resulting warpage. Based upon this correlation, the evaluators can easily identify those parameters which produce minimum stress, thus avoiding potential for breakage and damage during reflow operations.Type: ApplicationFiled: May 28, 2008Publication date: December 3, 2009Applicant: International Business MachinesInventors: Eric Duchesne, Julien Sylvestre
