TSMC, whose clients include tech giants such as iPhone maker Apple Inc , saw profit in the January-to-March period soar 90.6% from a year earlier, beating market forecasts. It also marked the company's strongest quarterly profit growth in nearly 10 years.

TSMC said on Thursday the coronavirus was expected to hit demand for electronics, including smartphones, but it would be balanced by strong demand for faster chips.
