TSMC, the world's biggest contract chipmaker, said on Friday its November sales rose 21.7 percent from a year ago, but fell from the previous month amid slower technology demand.

Taiwan Semiconductor Manufacturing Co Ltd (TSMC) had unconsolidated sales of T$35.72 billion ($1.19 billion) last month, compared with T$29.349 billion the same month a year ago and October's T$37.37 billion.
