A number of chip enterprises in China have halted production temporarily, including suppliers of semiconductors for foreign companies, amid a severe nationwide power shortage due to soaring coal prices and policies to reduce energy consumption.

CWTC, a semiconductor packaging material supplier for NXP and Infineon Technologies, released a notice on Sunday saying that its factory in Suzhou, Jiangsu had suspended semiconductor production from September 26 to 30, in accordance with the local policy on power reduction.
