Pegasus™ 500 Series Coatings

2022-06-29
●Entegris’ Pegasus™ 500 series coatings are a family of precision-engineered PVD coatings tailored for fluorine and chlorine plasma etch applications. They are aluminum-based oxynitride coatings deposited at low temperatures.
●Pegasus 500 series coatings can be deposited on aluminum, alumina, stainless steel and other commonly used substrate materials, with superior adhesion. These coatings are highly transparent in the visible and IR range. They are of high purity, exhibit homogeneous microstructure and are conformal to the substrate surface.
●Entegris’ Pegasus 500 series coatings are dense and excellent barriers to corrosive chemistries in a semiconductor etch environ-ment, protecting surfaces from erosion and minimizing particle generation. The coatings are superior in etch resistance performance compared to plasma sprayed coatings since they are dense, have good cohesive strength and are not prone to particulation. This improves device yield and improves productivity of semiconductor etch tools in a manufacturing environment.
●BENEFITS:
■Fluorine and chlorine etch resistance
■Oxidation resistance
■Low particle generation
■Dense and transparent
