Foundries 10nm yield rates lower-than-expected
Both Samsung and TSMC have claimed they have 10nm in "high" volume production at the moment. Yeah right.
That bodes well for TSMC's 7nm which is supposed to go "HVM" in H1'18, certainly if you know their 7nm will make use of quadruple patterning, which is literally twice as hard as double patterning .
How low are TSMC and Samsung willing to drop their yields to meet mobile phones' customer demands? Well, I guess as long as their customers are willing to pay per wafer (lower yields = more wafers = higher cost for customers), until they move to Intel.
Edit: Poor yields apparently mean below 50%. Impressive. http://www.fool.com/investing/2016/12/17/taiwan-semiconductor-mfg-co-ltd-to-start-building.aspx

TSMC is scheduled to start making Apple's A10X chips for the next-generation iPad series slated for launch in March 2017. Unsatisfactory yields for the foundry's 10nm process could disrupt the schedule, the sources indicated.
Meanwhile, yield rates for Samsung's 10nm process technology have been low prompting Qualcomm to turn cautious about its product roadmap for 2017, the sources said. Qualcomm originally planned for the Snapdragon 835 and other chips including the 660 (codenamed 8976 Plus) built using Samsung's 10nm process, but has revised its roadmap by having only the 835-series made using the newer node technology.
