LONDON – Foundry Taiwan Semiconductor Manufacturing Co. Ltd. has hit back at analysts who have said it has yield problems with its 28-nm CMOS manufacturing processes.

Maria Marced, president of TSMC Europe, repeated what has been said before by herself and other TSMC executives before; that defect density reduction is on track for the 28-nm node and ahead of where TSMC was with 40/45-nm process technology at an equivalent stage in its roll out.
