Selective Etchants

Applications

Daxin Materials offers a comprehensive portfolio of etchant solutions engineered to deliver tunable selectivity across diverse materials and metals. Featuring high metal loading capabilities, Daxin’s selective etchants significantly lower processing costs while reducing waste treatment volume. Furthermore, by leveraging crystal orientation differences, our specialized formulations achieve low copper undercut and superior etch uniformity, making them ideal for fine-pitch packaging copper etching applications. Daxin also provides tailored selective etchants compatible with various protective or barrier metals to precisely preserve critical line width and line space (L/S) dimensions.
