Eastman EastaPure™ DE Solvent

Eastman EastaPure™ DE solvent is the 9th product to be included in our current line of EastaPure products. Eastman EastaPure™ DE is a very polar, slow evaporating, water-miscible solvent with a mild odor providing low trace metals content for sensitive electronic applications. It is an active solvent for epoxy resins, cellulose acetate butyrate, nitrocellulose and other resin and polymeric materials. High-purity specifications (low trace metals) are required for solvents in semiconductor chip manufacturing, and special handling and storage procedures are used to maintain the high-purity specifications. Eastman EastaPure™ DE is being presented for photoresist applications/formulations, specifically for phtotoresist removers and strippers. Solvent based strippers are designed to strip photoresist and remove veils from sidewalls and multiple combinations of residues in wafer processing. Today, unique formulations typically address either bulk photoresist removal or residue removal, though some do both. High solvency, high stability, low volatility, high rinseability and complete solubility in water are desired system characteristics in photoresist removing and stripping solutions. Eastman EastaPure™ DE exhibits these desired properties, thus making it an excellent choice for these semiconductor applications. Eastman EastaPure™ DE solvent may also be utilized in edge-bead removal processes after spin coating. Because solvents are the basis for photoresists, solvent systems are utilized in edge bead remover formulations. Edge bead removers are specifically formulated to quickly and efficiently remove edge beads that build up during the spin coat process. A Certificate of Analysis (COA) will be provided with each shipment.
