Understanding Wafer Cleaning Equipment

Wafer cleaning equipment is designed to remove various types of contaminants—such as particles, organic and inorganic impurities, and metallic residues—from semiconductor wafers. This cleaning process is essential to prevent defects and ensure the optimal performance of semiconductor devices. Wafer cleaning typically involves multiple cleaning steps, including wet cleaning, dry cleaning, and vapor phase cleaning, each targeting specific types of contamination.

Types of Wafer Cleaning Equipment

1. Wet Cleaning Systems: Utilize chemical solutions and deionized water to clean wafers. These systems are highly effective in removing particles, organic, and metallic contaminants.
2. Dry Cleaning Systems: Use gases or vapors, such as ozone or plasma, to clean wafers without water. These systems are essential for avoiding watermarks and minimizing chemical waste.
3. Cryogenic Cleaning Systems: Employ frozen CO2 particles to remove contaminants, offering a water-free and chemical-free cleaning alternative.
4. Scrubbing Systems: Include brush or megasonic scrubbers to physically remove contaminants from wafer surfaces. These systems are particularly effective for particle removal.
