TSMC ramps volume production of Apple’s 20nm A8 processor

“Taiwan Semiconductor Manufacturing Company (TSMC) has confirmed that its 20nm wafer starts were delayed recently due to a specification issue of materials used in its CMP (chemical mechanical planarization) process,” Josephine Lien and Steve Shen report for DigiTimes. “The issue has been resolved, and no shipments will be delayed, said the wafer foundry house.”

“TSMC began volume production of its 20nm process node at the beginning of 2014, focusing on Apple’s A8 processors, according to industry sources,” Lien and Shen report. “The yield rate of the 20nm process has been ramped up significantly since then, reaching a level ahead of schedule, the sources noted.”

MacDailyNews Take: Ah, dueling reports out of Asia. Looks like we’ll have to wait and see if anybody can figure out who’s really stamping what and how much for whom.

  1. TSMC can have the high end chips and Samsung can take the older chip production so they don’t learn anything about the new designs.
    It’s all above volume. If TMSC can be guaranteed to handle it then Samsung will lose the business.

  2. So they have been building the A8 since the first of the year. Is this production earlier then prior years? I’m only speculating here, but it would seem early for the iPhone. Maybe the chips are slated for a new device.
