On August 27, 2020, the Information Network of the China Semiconductor Industry Association issued an announcement on the “List of Top Ten (Strong) Semiconductor Companies in China in 2019”. ZJJH Electronics, a wholly-owned subsidiary of HZLA Microelectronics Technology Group, which was recently listed on China’s A shares "Technology Co., Ltd." ranks the chief among the "Top Ten Chinese Semiconductor Materials Companies in 2019".
Public information shows that ZJJH is a high-tech enterprise dedicated to the development and production of semiconductor materials. The company is a semiconductor enterprise in mainland China with a complete industrial chain of silicon monocrystalline ingots, silicon abrasive wafers, silicon polished wafers, silicon epitaxial wafers, and chip manufacturing.
As the parent company of ZJJH, HZLA is mainly engaged in the research and development, production and sales of semiconductor silicon wafers and discrete semiconductor devices, as well as the production and sales of finished semiconductor discrete devices. The main products of the company's semiconductor discrete device chips include Schottky diode chips, MOSFET chips, etc.; the main product of semiconductor discrete devices is Schottky diodes.
Since HZLA acquired ZJJH in 2015, the company's industrial chain has extended to the upstream semiconductor wafer R&D, production and sales. The company's main semiconductor wafer products include silicon polishing wafers, silicon polishing wafers, silicon epitaxial wafers, etc., while subsidiary ZJJH is mainly engaged in 12-inch semiconductor wafer business; Leon Dongxin is mainly engaged in microwave radio frequency integrated circuit chip business.
Among them, ZJJH has long been committed to the research and development and production of high-tech and high-value-added semiconductor wafers. It has complete processes and production capabilities for silicon monocrystalline ingots, silicon abrasive wafers, silicon polished wafers, and silicon epitaxial wafers. In 2004, the company began mass production and sales of 6-inch semiconductor silicon polished wafers and silicon epitaxial wafers, becoming the earliest enterprise in China to mass-produce 6-inch silicon wafers.
As early as 2009, ZJJH 8-inch semiconductor silicon epitaxial wafers began mass production and sales, achieving a breakthrough in the supply of 8-inch silicon wafers in China. After that, by undertaking the Eleventh Five-Year National 02 Special Project, the company fully improved the existing industry and has a full range of 8-inch wafers. Ability to mass produce silicon single crystal ingots, silicon polished wafers and silicon epitaxial wafers.
In addition, ZJJH has also developed 12-inch single crystal growth core technology, as well as a series of key technologies such as wafer chamfering, grinding, polishing, and epitaxy. The large-scale industrialization of the above-mentioned 8-inch semiconductor wafer is related to the 12-inch semiconductor wafer. The technology has passed the national 02 special acceptance in May 2017, which also marks that ZJJH has been at the forefront of China's large-size semiconductor wafer production process research and development.
Relying on qualification barriers, looking at the global market
In the semiconductor industry, if a company wants to maintain its core competitiveness for a long time, it must continue to invest in R&D and maintain efficient R&D efficiency. From 2015 to 2019, the R&D expenses of HZLA increased from 41.7682 million to 96.9932 million. The company’s R&D investment continued and stable.
As of March 31, 2020, the company has more than 300 R&D and technical personnel. The company's core technology in the production of semiconductor wafers and semiconductor discrete device chips is industry-leading, and has won the second prize of the National Technology Invention Award, the first prize of Zhejiang Province Technology Invention, and the China Semiconductor Innovative Products and Technology Award. Today, HZLA has been recognized as a national innovative pilot enterprise, with provincial key enterprise research institutes and municipal academician workstations.
Over the years, HZLA has continued to invest heavily in research and development expenses to develop new products and process technology improvements. From 2017 to the first quarter of 2020, the company’s annual investment in technology research and development accounted for 5.63%, 7.08%, and 8.14 of the year’s operating income respectively. % And 7.31%. As of March 31, 2020, the company has dozens of authorized patents.
With a strong R&D team, deep technology accumulation and continuous R&D investment, HZLA has become a high-tech enterprise with strong influence in the industry. At present, HZLA is able to control product quality in accordance with international SEMI standards, Chinese national standards, national standards for sales destinations, and customer specific requirements, which has formed a strong qualification barrier.
Under strict quality control system and high-standard quality assurance, HZLA strives to develop high-end customers at home and abroad, including ONSEMI, AOS, Toshiba Japan, Taiwan Hanlei and other internationally renowned multinational companies, and the company is also SMIC and Hua Hong The important suppliers of domestic related companies such as Grace and China Resources Microelectronics have passed the strict audit and certification of the above-mentioned company's product quality system, product technology and product quality, which provides the prerequisite for the smooth sales of the company's products.
