Under the increasingly strict restrictions on the development of the domestic semiconductor industry overseas, the whole country has strengthened the national strategic scientific and technological strength, which is expected to inject strong momentum into the development of the domestic semiconductor industry. Domestic substitution in the field of semiconductor is expected to develop rapidly with the strong support of the country.
The third generation of semiconductor material is gallium nitride GaN, silicon carbide SiC, zinc oxide ZnO, diamond C, etc., among which silicon carbide SiC and gallium nitride GaN are the main representatives. SiC and GaN are more excellent in terms of bandwidth gap, dielectric constant, thermal conductivity and maximum working temperature. Leading companies in 5G communications, new energy vehicles, photovoltaics and and other fields are gradually using third-generation semiconductors, and they are expected to achieve a comprehensive replacement when costs drop. Compared with silicon-based MOSFETs and IGBTh, SiCMOSFETs have more advantages in switching efficiency, loss, size, frequency, volume and other indicators. Compared with SiCMOSFETs and Si MOSFETs of the same specification, the volume can be reduced by 1/10, and the on-resistance can be reduced to 1/200. Compared with SiC-MOSFETs and Si-IGBTs of the same specification, the energy loss is less than 1/4. Against the backdrop of the comprehensive advantage in SiC product performance, enterprises mainly composed of traditional power manufacturers at home and abroad have begun to accelerate the layout of SiC products, and the domestic and foreign markets will usher in a market structure of heroes.
At present, although foreign companies have first-mover advantages in technology, production capacity, etc., the SiC industry has a relatively short development history and a relatively small gap between home and abroad. Against the backdrop of high demand, domestic companies are expected to accelerate the realization of domestic substitution.
Huan Securities points out that overseas leading companies have first-mover advantages, and is ahead of China in terms of product and production capacity in the short term. But overall, the SiC industry has a relatively short history of development, and domestic companies are expected to overtake.
Here, by integrating the latest research reports of more than 10 securities companies such as Tianfeng, Anxin , Guoxin, etc., it brings 4 company profiles to fans for reference only.
1 and Qingyi Optoelectronics
companies are engaged in the research and development, design, manufacturing and sales of mask version. They are one of the earliest and largest mask makers established in mainland China. The company has increased the production capacity of the semiconductor chip mask version and shortened the delivery cycle, optimized the product structure, and increased the market share of the segmented market. At the same time, a major supplier of semiconductor chip mask protective film in China has stopped production due to the epidemic, which has negatively affected the domestic supply chain. The growth rate of semiconductor chip mask version business is temporarily limited by production capacity. It is expected that after the above short-term negative factors are alleviated, the company's production capacity will increase significantly, and it is expected to rapidly increase its market share in the segment. --Anxin Securities
2, Luwei Optoelectronics
is the only manufacturer in China that can cover the entire generation of G2.5-G11 production lines. According to the company's prospectus, the IC mask version of the 90nm and below process in my country currently relies on imports, and the 30 wafer production lines that have been put into production and under construction in China have reached 30, and there are huge room for domestic substitution. The company has achieved mass production of 250nm IC mask version, meeting the application of advanced IC packaging, IC devices, advanced fingerprint module packaging, high-precision sapphire substrate (PSS) and other product applications. The company has mastered the core technology of 180nm/150nm IC mask plate manufacturing, and the existing IC mask plate manufacturing technology covers third-generation semiconductor-related products. --Anxin Securities
3, Chengchang Technology
is a major enterprise engaged in the development of phased array T/R chips in China, and is one of the few companies in China that can provide complete solutions for phased array T/R chips. With the advancement of the construction of satellite Internet of Things, the company's satellite-based phased array T/R chip is expected to continue to grow rapidly. The company's T/R chip is also one of the core components of phased array radar . Phased array radar is gradually replacing traditional mechanical scanning radars, and the market space is constantly increasing. The company's radar uses phased array T/R chips to have a lot of room for growth. --Shouchuang Securities
4, Zhuzhu Technology
companies are constantly expanding in semiconductor-related business fields, from high-purity process systems to wet process equipment.Since 2021, the Hefei wafer regeneration project has officially climbed mass production. Hefei's wafer regeneration and component cleaning project is the first 12-inch wafer regeneration line to be put into production in China. The component cleaning project is the first complete anode production line in China, with an annual output of 1.68 million wafer regeneration and 1.2 million semiconductor parts regeneration capacity. The company has formed a strategic layout around the trinity of equipment, materials and processes in the semiconductor industry. --Shenwan Hongyuan
