Gus Richard, a chip analyst at Piper Jaffray, has said Apple has begun the process of reducing its dependency on Samsung for chipmaking, Cnet has reported. "Apple is working with TSMC at 20 nanometers," said Richard, referring to Taiwan Semiconductor Manufacturing Co's most advanced 20-nanometer (nm) manufacturing process. This shift will not happen overnight, though. "They'll ramp down Samsung and ramp up TSMC. And some products will get some of one and some of the other," Richard said.
