Dongbu's update on its 0.13-micron plans comes at a time when a number of major silicon foundry companies are reportedly having trouble reaching acceptable yields on their copper-based 130-nm (0.13-micron) processes. In nearly all cases, Asian foundry companies have not admitted to any problems publicly, but responses in recent conference calls indicate that 0.13-micron technologies are still somewhat in debug,” or early-learning/yield-improvement” stages.
