-
- This provides high strength – to – weight ratio, allowing for fast and precise movement while minimizing the load on the drive mechanisms. The arm has a reach of 600 mm, enabling it to access multiple process chambers within a typical semiconductor cluster tool.
- Drive System: Equipped with high – precision servo motors and harmonic drives. The servo motors offer high torque and precise speed control, while the harmonic drives provide zero – backlash operation, ensuring accurate positioning of the wafer. The arm can move at a maximum speed of 2 m/s and has an acceleration of 5 m/s².
- End – Effector: The end – effector, which comes in contact with the wafer, is made of a soft, non – contaminating material such as PEEK (polyether ether ketone) with a special coating. It has a vacuum – based gripping mechanism that can securely hold wafers of different diameters, typically ranging from 100 mm to 300 mm.
- Functional Features:
- High Precision Positioning: The robot arm can position the wafer with an accuracy of ±0.1 mm. This is crucial for ensuring that the wafer is correctly placed in each process chamber, preventing misalignment that could lead to device defects.
- Contamination Control: The use of non – contaminating materials and a sealed design prevent the introduction of particles or chemical contaminants onto the wafer surface during transfer. This is essential for maintaining the high – purity requirements of semiconductor manufacturing.
- Flexibility: The arm can be programmed to follow different transfer paths and handle various wafer sizes and types. This makes it suitable for use in a wide range of semiconductor processes, from front – end wafer fabrication to back – end packaging.
- Application Scenarios:
- Automated Wafer Handling Systems: Integrated into automated wafer handling systems in semiconductor fabs, where it transfers wafers between cleaning, deposition, etching, and inspection stations. This improves production efficiency and reduces the potential for human – induced errors.
- Cleanroom Environments: Due to its contamination – control features, it is well – suited for use in cleanroom environments where maintaining a high level of cleanliness is critical for semiconductor device quality.
