• allowing it to accommodate wafers of different sizes, typically up to [max_wafer_size] millimeters in diameter.
• Process Pressure: Can operate at a wide range of process pressures, from atmospheric pressure down to [low_pressure] mTorr, depending on the cleaning process requirements.
• Chemical Delivery System: Equipped with a precise chemical delivery system that can accurately dispense various cleaning chemicals, such as deionized water, hydrofluoric acid (HF), hydrogen peroxide (H₂O₂), and ammonia – based solutions. The flow rate of each chemical can be controlled within a range of [min_flow] to [max_flow] milliliters per minute.
• Heating and Cooling System: The system has a built – in heating and cooling system to control the temperature of the cleaning solutions and the wafer. The temperature can be adjusted from [min_temp] °C to [max_temp] °C with an accuracy of ±[temp_accuracy] °C.

Functional Features:

• Multiple Cleaning Modes: Offers several cleaning modes, including single – wafer spin – spray cleaning, batch immersion cleaning, and ultrasonic cleaning. Single – wafer spin – spray cleaning is suitable for high – precision cleaning of individual wafers, where the wafer is rotated at high speed while cleaning chemicals are sprayed onto its surface. Batch immersion cleaning allows multiple wafers to be cleaned simultaneously by immersing them in a cleaning solution. Ultrasonic cleaning uses high – frequency sound waves to generate cavitation bubbles in the cleaning solution, which effectively remove contaminants from the wafer surface.
• Particle Removal Efficiency: Highly efficient in removing particles from the wafer surface. It can achieve a particle removal efficiency of over [particle_removal_efficiency]% for particles with a size of [particle_size] micrometers and larger, ensuring that the wafer surface meets the stringent cleanliness requirements of semiconductor manufacturing.
• Chemical Recycling and Purification: Incorporates a chemical recycling and purification system to reduce chemical consumption and waste generation. The used cleaning chemicals are collected, filtered, and purified before being reused, which not only saves costs but also minimizes the environmental impact of the cleaning process.
• Automated Wafer Handling: The system is equipped with an automated wafer handling mechanism that can load and unload wafers from the cleaning chamber without human intervention. This reduces the risk of wafer damage and contamination during the handling process and improves the overall efficiency of the cleaning operation.

Application Scenarios:

• Pre – Deposition Cleaning: Before the deposition of thin films on the semiconductor wafer, it is essential to clean the wafer surface to remove any contaminants that could affect the adhesion and quality of the deposited film. The wafer cleaning system is used to perform this pre – deposition cleaning, ensuring a clean and smooth surface for the deposition process.
• Post – Etching Cleaning: After the etching process, the wafer surface may be covered with etching residues and by – products. The cleaning system is used to remove these residues, preventing them from interfering with subsequent processing steps and ensuring the proper functioning of the semiconductor devices.
• Final Cleaning before Packaging: Before the semiconductor wafers are packaged into individual devices, a final cleaning step is performed to ensure that the wafers are free from any remaining contaminants. The wafer cleaning system provides this final cleaning, ensuring high – quality and reliable semiconductor products.
