Characteristics

These materials are defined by ultra-high purity (to prevent micro-contamination), precise chemical composition, and exceptional consistency. They often possess specific reactivity or physical properties, such as photosensitivity, selective etch rates, and thermal stability.

Uses

They are essential in semiconductor manufacturing for patterning circuits (photoresists), etching layers (acids), depositing films (CVD precursors), and polishing wafers (CMP slurries). In electronics assembly, they are used for plating PCB traces, soldering components (solder paste/flux), and printing conductive pathways.
