Teradyne, Tokyo Electron launch AI test

Teradyne and Tokyo Electron have announced an integrated test cell solution for known good device (KGD) screening, targeting devices used in AI and data center applications. This collaboration combines Teradyne's UltraFLEXplus platform with Tokyo Electron's Prexa SDP (Singulated Device Prober) to offer a production-ready path for high-quality device screening in advanced 2.5D/3D packaging flows. The solution addresses the critical need for KGD screening in chiplet-based designs, where a single defective die can compromise an entire high-value package. Shannon Poulin, president of Teradyne's Semiconductor Test Group, emphasized the solution's ability to meet the rigorous demands of AI device innovation, providing thermal precision, power density, and digital performance. This commercially available solution aims to reduce integration risk for high-volume manufacturing and ensure the reliability and performance of next-generation AI and data center architectures.
