This is despite some flatness in one of TSMC's key markets, the smartphone sector, and a more general malaise around US-China trade tensions. The latter may have been responsible for falling sales at fellow Taiwan foundry United Microelectronics Corp. (UMC).
September sales at TSMC were NT$102.17 billion (about US$3.32 billion) up 7.6 percent from the same month a year before but down 3.7 percent from August. TSMC's revenue for first nine months of the year was NT$752.75 billion (about US$24.45 billion), up 1.5 percent on the same period in 2018.
TSMC continues to outperform both the general semiconductor market and the foundry market partly due to its leading position in 7nm manufacturing.
September sales at foundry UMC were NT$10.83 billion (about US$352 million) down 8.7 percent on an annual basis. UMC's revenues for the first nine months of 2019 total NT$106.35 billion (about US$3.45 billion), down 8.1 percent compared with the same period in 2018.
