- Product Introduction: In semiconductor manufacturing, wafer cleaning is a crucial step to remove contaminants such as particles, organic residues, and metal ions from the wafer surface. This cleaning nozzle is designed to deliver cleaning solutions precisely and effectively during the wafer cleaning process, ensuring high – quality cleaning results.
- Technical Specifications:
- Nozzle Material: Usually made from high – purity, corrosion – resistant materials such as PFA (perfluoroalkoxy) or PTFE (polytetrafluoroethylene). These materials can withstand exposure to various cleaning chemicals without degradation and do not introduce additional contaminants to the wafer.
Detailed content

- Flow Rate Range: Can control the flow rate of the cleaning solution within a specific range, typically from a few milliliters per minute to several liters per minute, depending on the cleaning process requirements and the size of the wafer.
- Spray Pattern: Produces a well – defined spray pattern, which can be adjusted according to the cleaning needs. Common spray patterns include fan – shaped, conical, or flat – jet patterns, each suitable for different types of contaminant removal and wafer geometries.
- Functional Features:
- Uniform Spray Distribution: Designed to provide a uniform spray of the cleaning solution across the wafer surface. This ensures that all areas of the wafer receive the same amount of cleaning action, reducing the risk of incomplete cleaning or over – cleaning in certain regions.
- Precise Flow Control: Equipped with a flow control mechanism, such as a needle valve or a mass flow controller integrated into the nozzle assembly, to accurately regulate the flow rate of the cleaning solution. This allows for fine – tuning of the cleaning process based on the type and level of contamination on the wafer.
- Easy Maintenance and Replacement: The nozzle is designed for easy disassembly and cleaning. In case of clogging or wear, it can be quickly replaced to minimize downtime in the cleaning process.
- Application Scenarios: Used in various wafer cleaning equipment, such as single – wafer spin – rinse – dryers and batch – type wafer cleaners. In single – wafer spin – rinse – dryers, the nozzle is positioned above the rotating wafer to spray the cleaning solution evenly across the surface while the wafer spins. In batch – type cleaners, multiple nozzles may be arranged to clean multiple wafers simultaneously.
