Semiconductor EL-S Grade Phosphoric Acid
Application: EL-S (Electronic-Grade) phosphoric acid is used in semiconductor manufacturing primarily for cleaning wafers and etching, a process that removes unwanted layers of material to shape microchips. Its high purity is critical for these applications, which also include etching insulating and conductive films, and preparing substrates before other processes.
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.
Application
Etching electronic materials
Shipping Options
Plastic container (25kg,30kg), Drum (300kg), Tank truck load (10t)
(Packaging options for EL-S grade）

Semiconductor Chip Dicing Cleaning Fluid
Application: YNK-708 dicing fluid is specifically developed for various wafer dicing processes. It effectively removes silicon dust and prevents electrochemical corrosion of bond pads during the dicing process.
Semi-Aqua Bio-Cleaner
Application: 1139X is a Halide/Halogenated solvent free new performance Semi-Aqua bio-cleaner formulated to remove post assemblies flux residues soldered with rosin-based or no-clean solder-paste fluxes. It is also an excellent all-purpose cleaner and degreaser, compatible to be used for rosin-based and no-clean and organic acid flux. This cleaner has high solvency ideal for assemblers who want to remove assemblies flux residues using a more environmentally friendly safer solvent, replacing more toxic Chlorinated/Halogenated solvent.
