In 1996, Shanghai Huahong Microelectronics Co., Ltd. (now Huahong Group) was established as part of China's national efforts to boost its IC industry. In 1997, a joint venture HHNEC was formed between Huahong and
NEC China to produce DRAM for NEC. The company phased out DRAM production in 2003 and became a pure-play foundry. In December 2000, Grace Shanghai was formed by Grace Cayman as a pure-play foundry. In 2011, HHNEC and Grace Shanghai was merged to form Shanghai Huahong Grace Semiconductor Manufacturing Corporation, which later fell under Hua Hong Group, a fully owned subsidiary of Hua Hong Semiconductor Limited. In 2014, Hua Hong was listed on the
Hong Kong Stock Exchange. In 2023, the company seeks to raise capital by listing themselves on the
Shanghai Stock Exchange. This was to build their own advanced chip technologies amid
U.S. restrictions. In October 2025, the
United States Department of Defense stated that Hua Hong Semiconductor merits inclusion on a list of companies linked to China's military. In April 2026, the
United States Department of Commerce ordered multiple U.S. chip equipment makers to halt tool shipments to Hua Hong, citing national security concerns. ==Locations==
