In 1976, Johnson Enterprise Co., Ltd. was formally registered in Hong Kong, mainly engaged in the international trade of electronic products. In order to keep pace with the continuous development of the business, it was renamed Johnson Electronics Co., Ltd. in 1985. After continuous efforts, the company gradually expanded its business to the field of semiconductor manufacturing. In order to integrate the expansion of manufacturing business and the development policy of groupization, it was renamed Johnson Electronics (Group) Co., Ltd. in 1997, becoming a comprehensive international enterprise integrating production and trade. Its wholly-owned subsidiaries include Shanwei Johnson Electronics Co., Ltd. and Johnson Semiconductor Co., Ltd.
