Taiwan Semiconductor Manufacturing Company – better known as TSMC – has posted record Q4 profits after taking around 60% of the orders for the A8 chip in the iPhone 6/Plus. Nasdaq reports the company’s net profits for the quarter rose 79% year-on-year.

TSMC’s move into 20-nanometer chip production enabled Apple to reduce its reliance on Samsung for the A8 chip, with the chipmaker saying that it is making further investment in more advanced chip-making technology. It plans to increase its capital expenditure this year to $11.5-12B, up from $9.52B last year.

TSMC, the world’s largest contract chip maker by revenue, said Thursday that net profit for the three months ended Dec. 31 was 79.99 billion New Taiwan dollars (US$2.51 billion), up from NT$44.81 billion a year earlier.

A KGI report yesterday predicted that TSMC would pick up 100% of orders for the A9X chip expected to be used in the next-generation iPad, as well as making all of the A10 chips for the nominal iPhone 7, and all the S2 chips for the second-generation Apple Watch.
