EKC® Strippers & Rinses
Strippers to remove photoresist used during the lithography process
Organic materials specifically formulated to remove positive & negative photoresist from substrate surfacesEnable removal of positive- and negative-tone photoresists as well as plasma-hardened residues, and which are compatible with a wide variety of metals required to form LED contacts.Formulations optimized to effectively remove thick and thin resists used for TSV masks and wafer bumping by solder electroplating or stencil printing. -
