Bloomberg:
Apple Inc. manufacturing partner Taiwan Semiconductor Manufacturing Co. has started mass production of next-generation processors for new iPhones launching later this year, according to people familiar with the matter.
The processor, likely to be called the A12 chip, will use a 7-nanometer design that can be smaller, faster and more efficient than the 10-nanometer chips in current Apple devices like the iPhone 8 and iPhone X, the people said.
7 nanometers is the next planned design threshold for semiconductor manufacturing, with 5 nanometer designs about 3 years away.
To give a sense of the curve here:
- 2008: 45nm
- 2010: 32nm
- 2012: 22nm
- 2014: 14nm
- 2017: 10nm
- 2018: 7nm
- 2021: 5nm
A nanometer is one billionth of a meter. Next step smaller? An angstrom is one tenth of a nanometer. So the 7nm threshold we are about to breach is also the 70 angstrom threshold. Tiny.
