AMAT 0050-21180
- Product Name: AMAT 0050 – 21180 Semiconductor Wafer Cleaning System Nozzle
- Product Introduction: This nozzle is a critical component of semiconductor wafer cleaning systems. Wafer cleaning is an essential step in semiconductor manufacturing to remove contaminants such as particles, organic residues, and metal ions from the wafer surface before and after various process steps. The nozzle is responsible for delivering cleaning fluids, such as deionized water, chemicals, or a combination of both, in a precise and controlled manner to achieve effective cleaning.
- Technical Specifications:
- Material: Made from high – purity, chemically resistant materials such as polyether ether ketone (PEEK) or special ceramics.
Detailed content
-
- These materials can withstand the corrosive nature of cleaning chemicals and the high – pressure conditions during fluid delivery.
- Nozzle Orifice Size: The orifice size is carefully selected based on the desired flow rate and spray pattern. It can range from a few micrometers to several hundred micrometers, depending on the cleaning requirements. A smaller orifice size can produce a finer, more focused spray, while a larger orifice may be used for higher – volume cleaning applications.
- Fluid Pressure Rating: Can operate under high – pressure conditions, typically ranging from a few bar to several tens of bar. This high – pressure capability ensures that the cleaning fluid can effectively remove contaminants from the wafer surface, especially for stubborn or adhered particles.
- Functional Features:
- Spray Pattern Control: Designed to produce specific spray patterns, such as a conical, flat – fan, or full – cone pattern. The spray pattern can be adjusted to cover the entire wafer surface uniformly or to target specific areas that require more intense cleaning.
- Chemical Compatibility: Engineered to be compatible with a wide range of cleaning chemicals used in semiconductor manufacturing, including acids, bases, and solvents. This allows for flexible cleaning processes and the ability to adapt to different process requirements.
- Self – Cleaning Capability: Some nozzles may have a self – cleaning feature to prevent clogging. This can be achieved through the use of special materials or designs that allow for easy removal of any accumulated particles or chemical residues.
- Application Scenarios: Used in semiconductor wafer cleaning equipment in fabs. It is an important part of pre – clean steps before photolithography, etching, and deposition processes to ensure a clean wafer surface for high – quality device fabrication. It is also used in post – clean steps to remove any process – related contaminants after these operations.
