A global shortage of semiconductors has swelled order books for Taiwanese chip-makers like Taiwan Semiconductor Manufacturing Co Ltd (TSMC) 2330.TWTSM.N. Gross domestic product (GDP) likely grew 2.9% in January-March versus a year earlier, the poll of 18 economists shows, after it rose 4.86% year-on-year in the fourth quarter.
