Project Background

The Prexa™ MS by Tokyo Electron is a fully automated 300mm wafer prober designed specifically for testing memory devices, particularly advanced DRAMs. This equipment is crucial in semiconductor production, providing unmatched efficiency, scalability, and precision. The automation integrated into the Prexa™ MS is essential for maintaining throughput and accuracy in high-volume production environments, where errors can be costly. As memory devices evolve, they require more test pins and generate more heat. To meet these challenges, the Prexa™ MS is equipped with an ultra-load capacity of up to 1000 kg and precise high-load control features.

 

Solution

To manage the increasing complexity of semiconductor testing and the demands of robust data communication, Tokyo Electron integrated the Volktek Switch INS-8408A into the Prexa™ MS. The INS-8408A was selected for its exceptional reliability and consistent performance, making it ideal for the high demands of semiconductor production. This switch plays a critical role in ensuring stable and efficient LAN communication between the control units of the Prexa™ MS, handling the large volumes of data generated during DRAM testing. The INS-8408A provides the necessary bandwidth and data handling capacity to maintain system integrity and operational efficiency.

 

Result

The integration of the Volktek Switch INS-8408A into the Prexa™ MS system has proven to be a successful application of network technology in advanced semiconductor manufacturing. The INS-8408A has demonstrated its capacity to meet the demanding requirements of high-load, high-performance semiconductor testing, ensuring robust and reliable network communication within this sophisticated environment. This integration supports the seamless transfer and management of test data, contributing to the overall efficiency and reliability of the Prexa™ MS in high-volume semiconductor production.

 

The Volktek Switch INS-8408A improved the Prexa™ MS's network connection capabilities, providing Tokyo Electron with a dependable, high-performance infrastructure. This technology provides accurate data transfer across the testing workflow, enabling the organization to maintain its competitive advantage in the memory device testing market.

 

Upstream and Downstream Devices

• Upstream Devices: These are typically the control units and servers that send control signals and testing protocols to the Prexa™ MS. The INS-8408A receives data from these sources for processing and communication.
• Downstream Devices: After processing the data, the INS-8408A transmits this information to other parts of the Prexa™ MS system, including the actuators that handle the physical manipulation of wafers and the diagnostic tools that analyze test results.
