Electronic Grade refers to ultra-high-purity chemicals and materials used in semiconductor and microelectronics manufacturing. These substances meet extremely strict purity standards (often 99.999% or higher) to prevent contamination that could damage sensitive components like silicon wafers, integrated circuits, and flat-panel displays. Key applications include wafer cleaning, etching, deposition, and lithography. Impurities—such as metals, particles, and moisture—are controlled at parts-per-billion (ppb) or even parts-per-trillion (ppt) levels. Electronic-grade chemicals (acids, solvents, gases) must comply with industry standards like SEMI and are handled in cleanroom environments to ensure precision and reliability in advanced electronics production.
