I think SMIC is at 28 nm.As for Silicon wafers, the purity for IC chips(11n+) and solar panels(6~7n) are completely different making them useless.
As for fabs, to 40 nm technology can't really handle present day CPUs.
SHANGHAI, Dec. 18, 2014 /PRNewswire/ -- Semiconductor Manufacturing International Corporation (SMIC; NYSE: ; SEHK: 981) and Qualcomm Incorporated (NASDAQ: ) today announced that its subsidiary, Qualcomm Technologies, Inc., and SMIC have achieved a major milestone in fabrication of 28nm Qualcomm® Snapdragon™ 410 processors. This milestone comes six months after SMIC and Qualcomm Technologies announced their initial plans to collaborate on 28nm wafer production. Snapdragon 410 is a leading-edge processor designed to enable a new class of smartphones and tablets at the high-volume tier through offering integrated LTE, high-performance graphics and imaging, 1080P HD display, 64-bit capable processing and a range of advanced modem features. This milestone represents an important step for SMIC in their 28nm process maturity as they become one of the first Chinese foundries to produce high-performance, low-power mobile processors at one of the industry's most advanced process nodes. This achievement builds on a longstanding wafer supply relationship between SMIC and Qualcomm Technologies that was recently extended in July to collaborate at the 28nm process node.
"The successful yield of 28nm process technology on high-performance, low-power Snapdragon mobile processors represents a major milestone for SMIC in increasing our competitiveness in the global foundry landscape," said Dr. Tzu-Yin Chiu, chief executive officer and executive director, SMIC. "Our collaboration with Qualcomm Technologies has been key in helping us to accelerate our 28nm technology development and achieve this key milestone within six months from the commencement of the collaboration. The maturity of our 28nm process represents a significant long-term growth driver for SMIC in support of Qualcomm Technologies and our customers globally."
"We're extremely pleased with the tremendous progress made by SMIC in achieving a critical milestone in 28nm process technology with the successful yield of Snapdragon 410 processors," said Murthy Renduchintala, executive vice president, Qualcomm Technologies, Inc., and co-president, QCT. "SMIC plays an important role in Qualcomm Technologies' supply chain in allowing us to expand our manufacturing footprint in China to better address the growing need for high- performance and low-power mobile devices with customers in the region and around the world".
China's SMIC to Launch 28nm Mass Production by Year-end 2014
April 14, 2014
SMIC (Semiconductor Manufacturing International Corporation) plans to launch mass production of 28nm technology at year-end 2014, with 20nm readiness in 2015, reported China' Securities Times on April 14. SMIC says 28nm to 45nm technology will be adopted by its second-phase expansion wafer fab in Beijing, which is slated for operation in September this year with a monthly capacity of 35,000 wafers. Aside from the Beijing fab, the company also has a fab under construction in Shenzhen, China. SMIC's 28nm technology can provide customers with MPW (Multi Project Wafer) services, including 28nm PS (PolySiON) and 28nm HKMG (High-K Dielectrics Metal Gate) processes, mainly applied to processors and chips for smartphones, tablets, and set-top boxes.
and alot more to provide argument that SMIC is 28 nm now, do you still want others article???
