In July 1998, Fudan Microelectronics was jointly founded by Fudan University's "National Key Laboratory of ASICs and Systems", Shanghai Commercial Investment Company and a group of entrepreneurs who dreamed of creating the best integrated circuit design company (chip design) in China. Since its establishment, the company has successfully established a pivotal position in the domestic integrated circuit design industry. The company was listed in Hong Kong on August 4, 2000 (stock code: 1385), becoming the first listed company in the domestic integrated circuit design industry. Today, Fudan Microelectronics has grown from more than 10 entrepreneurs to a company with more than 600 employees, with users all over the world. The company has attracted the attention of domestic and foreign peers with its excellent management, good development potential and outstanding performance. In 2011, Fudan Microelectronics was selected as the "Best Small and Medium-sized Listed Company" by the editors of Forbes Asia magazine.
