Semiconductor Chemicals: Enabling the Electronics Revolution
Semiconductor chemicals, also known as electronic-grade chemicals, are critical to the manufacturing of integrated circuits (ICs), microchips, and various electronic devices. These ultra-pure chemicals are essential in wafer fabrication, etching, doping, cleaning, and lithographic processes that define the intricate architecture of semiconductors. As global demand for electronics surges—from smartphones and data centers to EVs and AI devices—the role of high-performance semiconductor chemicals becomes increasingly vital.
Types of Semiconductor Chemicals
Etchants
Used to selectively remove layers of materials during wafer processing.
Examples: Hydrofluoric acid (HF), nitric acid, and phosphoric acid.
Photoresists and Developers
Light-sensitive materials used in photolithography to transfer circuit patterns onto wafers.
Types: Positive and negative photoresists, along with alkaline developers.
CMP Slurries (Chemical Mechanical Planarization)
Abrasive liquids used to flatten wafer surfaces for subsequent photolithography steps.
Customized for oxide, metal, and dielectric polishing
