The world’s biggest contract chipmaker, Taiwan Semiconductor Manufacturing Co., did better than feared, recording a 13.4% drop while the wider group of major assemblers and component makers fell 16.4% to NT$1.24 trillion ($38.7 billion) from a year earlier, according to data compiled by Bloomberg. TSMC has weathered sagging smartphone and laptop chip sales better than others thanks to demand for artificial intelligence accelerators it makes for Nvidia Corp.

Device assemblers Hon Hai Precision Industry Co., Compal Electronics Inc. and Quanta Computer Inc. led declines, though rival Pegatron Corp. managed to eke out growth in September after having the second-worst August in the group. Last month marked the steepest fall since June and extended August’s double-digit decline, leading to an 8.8% slump for the first nine months of the year.
