EL-S phosphoric acid
(Packaging options for EL-S grade)
Overview | This is our highest grade phosphoric acid, for which the level of particles that are fine contaminants has been reduced. Particles sticking to the surface of semiconductor wafers can cause defects in the semiconductor manufacturing process. By reducing impurities to the absolute minimum, this product can be used as an etching agent for semiconductors, which are sensitive to particles. |
