The near future, lang Cheng research and development of special chemical company gives a kind of new-style colophony that mix a bed, use at semiconductor production exceeds pure water mediumly. With already some Lewatit UltraPure 1296 MD mix bed colophony photograph to compare, new-style UltraPure 1296 MD PLUS mixes bed resinous the metallic content such as iron, zinc and natrium is lower. This product produces medium terminal polish filter as semiconductor, its are inchoate the analysis with installation adjacent already and current result detects the limit.
Lang Cheng will reveal his to professional audience on UltraPure Micro conference colophony of new-style ion exchange. This conference gets Kesasi at was in the United States to 12 days on October 10, 2023 Austin holds the city.
Lang Cheng liquid purifies Hans-Juergen Wedemeyer of manager of sale of technology of technical business department to express: "The resin of ion exchange of Lewatit UltraPure 1296 MD PLUS that produces in Germany is right the semiconductor industry that develops flourishingly on international, it is the implementation low cost, main component that can last and produces without breakdown.
LewatitUltraPure1296MDPLUS, Use at the most formidable task
The production of semiconductor and monitor needs to have sophisticated water treatment, in order to ensure the water that place uses achieves the purity of the requirement. Accordingly, the quality requirement of the system of ion exchange colophony that the chip of newest generation and tiny chip use to place is corresponding also taller. In addition, new analytic system can analyse low Ppt (1/-727379968) the ion inside limits. To the ion of certain type, they can achieve Ppq (ten million 1/100000000) limits. Want to achieve the semiconductor performance that modern industry place requires, the likelihood needs to amount to 200 processing measure. Be what what this needs to exceed pure water is offerred through sophisticated multistage technology. The most important step in unit process of cargo bandling includes to use colophony of standard ion exchange to have routine one class desalination, reverse osmosis, take off gas, super- filter and cross oxidation hydrogen purify, and the last phase is to use exceed the pure colophony that mix a bed to undertake terminal polish. Colophony of ion exchange of new-style Lewatit UltraPure 1296 MD PLUS is this last pace namely of special research and development, it is crucial to the success of whole craft.
After such processing exceed pure water to production of usable Yuwei chip etchs mediumly and clean a process. Wedemeyer says: “ anion and total capacity of cation exchange resinous are large, recovery capability is strong, because this is in,silicon of purify boron, 2 oxidation and metallic ion respect also have outstanding serviceability. ”
Wedemeyer complement says: “ sheet is dispersive of composition small bead dimension design can avoid accident of colophony of ion exchange of yin and yang to depart. Because colophony of ion exchange of Lewatit UltraPure 1296 MD PLUS used special manufacturing technology, of particle and TOC release a quantity extremely low. ”
