DigiTimes heard rumors that Samsung plans to expand its foundry capacity to 30,000 20nm wafer starts per month. The South Korean electronics giant seems poised to catch up with TSMC but both firms are still struggling with their 20nm yield rates. TSMC reportedly achieves just 20-30 percent yields, whereas those of Samsung are estimated to be as low as 10 percent. TSMC plans to roll out its 20nm volume production in early 2014 and will offer only one process at the node.
Samsung has stepped up the development of its 20nm process node, and already shifted a portion of R&D resources from 14nm to 20nm, said the sources. Samsung is looking to start offering 20nm process technology in early 2014, the sources indicated.
The sources did not identify how many options Samsung will offer at 20nm.
