Junpeng Bu, an MBA from Renmin University of China, entitled as a researcher of Institute of Semiconductors of the Chinese Academy of Sciences and a member of National Standard Committee of Artificial Crystal Materials, once served as Executive Deputy General Manager of CAS Jiaying Semiconductor Co., Ltd. and General Manager of China Crystal Technologies Co., Ltd. Engaging in semiconductor scientific research for over 35 years, he has been committed to R&D of semi-insulating GaAs and other crystal materials and made outstanding contributions to the rapid development of GaAs materials. At present, Mr. Bu works for Kangpeng Semiconductor as Board Chairman, leading to establish systems of technology R&D, production management, production schedule, sales and after-sales service.

Zhejiang Kangpeng Semiconductor Co., Ltd., established on November 5, 2018, mainly focuses on R&D, production and sales of GaAs materials. The company is jointly invested by Junpeng Bu's Beijing team that is responsible for investment, technology and operation, Xiamen Changelight Co., Ltd. and Anxin Capital which is responsible for investment. After Series-A funding, its company valuation reaches RMB700 million (USD103 million). Currently, the domestic market basically sources semi-insulating GaAs substrate materials by importing, while, to some degree, Kangpeng liberates GaAs substrate materials for RF chips from dependence on imports by developing products equivalent to Japan's Sumitomo. It's also worth noting that Kanpeng's semi-insulating products have been sold to EPISTAR Corporation, and will embrace a promising future because they have entered the international market already. In addition, Kangpeng's GaAs wafers are supplied to downstream manufacturers to mainly produce Huawei's face recognition terminal products, therefore, marking that Kangpeng becomes the upstream supplier of Huawei's industrial chain.
