Precision in Wafer Transportation and Control System

Custom Program Development for Wafer Placements

“Following wafer inspection, there is a need for warehouse separation. With our conveyor belt being quite long and multiple warehouses in place, we have faced challenges in the past where incorrect stopping positions resulted in wafer destruction, causing significant difficulties for us.”

The company's wafer inspection machine is inextricably tied to the manufacturing process for both finished and NG (Not Good) wafers, requiring an extremely precise transportation and control system. Acepillar developed a technical solution to maximize overall performance, ensuring that wafers remain intact and are not broken during transportation.

 

Acepillar combines DI Sensor technology with EtherCAT motion control cards to assure the safe transportation and precise placement of wafers. This enables real-time information transfer and control over the stopping distance of servo motors, which meets the requirements of real-time control.

 

The factory is massive, and the production line is miles long. The early Motion net layout required numerous wiring, resulting in a complicated wire structure with different connections such as pulse IO signals. However, with the change, the need for extensive wiring has been decreased. A single network cable may now be used for both connections and control, making installation and maintenance easier.

 

The pain points​ and solution

At first, pulse-type axis cards were used, and dealing with numerous axis required a large number of motion control card.

The incorporation of EtherCAT motion control cards has reduced the dependency on traditional motion control cards significantly. A normal motion control card is capable of managing 4-6 axis, however an EtherCAT motion control card can efficiently manage up to 32 axis.

The usage of traditional motion control cards in the manufacturing process can cause delays and dangers due to signal loss.

By using network cables for both interconnection and control, the system configuration is simplified. Furthermore, precise and real-time signal transmission ensures the exact transportation of wafers to their prescribed places.

The final placements of semiconductor wafers are not fixed, requiring precision in the transportation line.

Writing a custom program on your own takes a significant amount of work and testing for stability. The technical staff supports in customizing program development, resulting in greatly enhanced performance and stability compared to the original version.

The benefits of this technology extend beyond its detection accuracy to operational flexibility and scalability. Acepillar's highly flexible architecture enables for modification according on unique client needs, making it well-suited for larger and more sophisticated factories, particularly those in industries such as semiconductors or wafers that require accuracy in component and product movement. Furthermore, this technology allows for seamless connection with other production line equipment, helping to establish a more comprehensive and automated manufacturing environment.

We offer professional evaluations, site surveys, and planning.
