AMAT 3300-11385
- Product Introduction: This automated robot arm is a key element in semiconductor wafer handling systems. It is designed to precisely and rapidly move semiconductor wafers between different processing stations within a semiconductor fab, such as from load ports to process chambers and between different chambers during multi – step processes. Its high – precision operation and reliability are crucial for maintaining high production yields and minimizing wafer damage.
- Technical Specifications:
- Degrees of Freedom: Typically has multiple degrees of freedom, usually 4 – 6, which allow it to move in the X, Y, and Z directions as well as rotate around different axes.

- This enables it to reach various positions within the wafer handling area with high accuracy.
- Payload Capacity: Can handle wafers of different sizes, commonly 200 mm and 300 mm wafers. The payload capacity is designed to safely carry the weight of the wafer along with any additional handling fixtures, usually up to several kilograms.
- Positioning Accuracy: Has extremely high positioning accuracy, often in the range of sub – millimeters. For example, it can position a wafer within ±0.1 mm of the target location, ensuring proper alignment for subsequent processing steps.
- Speed: Can move at high speeds, with acceleration and deceleration capabilities to quickly transfer wafers between stations while minimizing the risk of wafer slippage or damage. The maximum speed can reach several meters per second, depending on the specific design and application.
- Functional Features:
- Wafer Gripper: Equipped with a specialized wafer gripper that can securely hold the wafer without causing damage. The gripper may use vacuum suction or mechanical clamping mechanisms, and it is designed to distribute the gripping force evenly across the wafer surface.
- Sensor Integration: Incorporates various sensors, such as vision sensors, proximity sensors, and force sensors. Vision sensors are used for wafer identification and alignment, proximity sensors detect the presence of objects to prevent collisions, and force sensors monitor the gripping force to ensure the wafer is held properly without being over – stressed.
- Software Control: Controlled by advanced software that allows for precise programming of movement paths, speed profiles, and handling sequences. The software can also interface with the overall fab control system to coordinate wafer handling with other process steps.
- Application Scenarios: Widely used in semiconductor fabs for automated wafer handling in cleanroom environments. It is an integral part of automated material handling systems (AMHS) that transport wafers between different process tools, such as photolithography machines, etchers, and deposition equipment, enabling high – volume and high – efficiency semiconductor manufacturing.
