Chen's speech included a call to "my friends at TSMC to give me more 40 nm parts," and a plea for improved via defectivity. D(i)ck James, a technology analyst at Chipworks (Ottowa, Canada), said via defects have shown up on ICs manufactured by TSMC. Chipworks has inspected products from graphics vendor ATI, now part of Advanced Micro Devices (AMD, Sunnyvale, Calif.). "The problem appears to be that when they cut a via, a residue of photoresist gets on the edge of the via, which creates a ring-shaped discontinuity in the metal," James said. "The discontinuity could create electromigration issues. We've seen the same problem on the upper metal levels on the ATI chips we've studied. It creates a reliability failure mode."
engineers dont spend their time laughing at the competition, they do their jobs. chipworks is a company that analyzes competitors products.
