The chair and CEO of Taiwan Semiconductor Manufacturing Co. Ltd (TSMC) has recognized that problems with the 28nm node was experienced by the company, but added that the said the problems were related to capacity, and not yield. Morris Chang likewise said that TSMC's 28nm yields have from the beginning sat within the company's targets.

"Yes, we had some difficulties with 28-nm, but those difficulties had to do with not having enough capacity, not yields," Chang said.

Chang, TSMC CEO, said the problems with the 28nmn node were not related to yield.

Chang acknowledged that TSMC has been dogged by persistent rumors about its 28nm yields. In January, Mike Bryant, a technology analyst with Future Horizons Ltd said TSMC was in trouble with its 28nm technology, saying the processes were not yielding well. Last month, unsubstantiated rumors circulated that TSMC had shut down its 28nm production in February. At the time, a TSMC spokeswoman declined to comment, citing company policy against commenting on rumors, but added that the firm's 28nm process was "normal."

Chang said TSMC's investments in capacity expansion for 28nm production have helped the firm alleviate the 28nm capacity crunch. He noted that TSMC planned to invest more than $7 billion in capital expenditures in 2012, up from about $7 billion in 2011, $5 billion in 2010 and $2 billion in 2009.

"With capacity coming online, I do believe the worst is behind us," Chang noted.

Taiwan IT publication Digitimes said that two TSMC customers, Qualcomm Inc. and Nvidia Corp., approached other foundries about producing 28nm chips for them because of tight 28nm capacity at TSMC. The report cited unnamed sources at semiconductor tool makers.
