PRODUCTS

Our diverse line of performance products o� ers the versatility needed to meet the toughest challenges in cleaning processes. Whether you're removing bulk photoresist on a rework process or post etch process, or residual polymer after a post ash process, Avantor Performance Materials can help.

PRS Series

The PRS series of formulated products are high performance organic solvents developed to maximize the removal and complete dissolution of bulk photoresist from a patterned wafer or � at panel surface. Speci� cally designed for wet bench applications, the PRS series is also highly e� ective in batch spray applications.

ALEG Series

A versatile series of formulated high performance organic solvents and semi-aqueous components, the ALEG product line is suitable for both bulk photoresist removal and post ash residue and polymer removal. Speci� cally designed for wet bench applications, the ALEG series also has proven to be e� ective in batch spray applications.

REZI Series

An environmentally friendly line of residue removers that are greater than 80% aqueous, REZI products are formulated to deliver the most e� ective removal of etch/ash residues and sidewall polymers from metal and via structures. They are speci� cally designed for use in wet bench and single wafer tool applications.
