Etching machine, a semiconductor chip equipment, is in the forefront of domestic substitution in the field of chip manufacturing. There are three core links, namely thin film deposition, lithography and etching. Etching is a process of selectively etching or peeling off the surface of a substrate or a surface covering film by chemical or physical methods to form a circuit pattern defined by photolithography.
Among them, lithography is the most complex, critical, expensive and time-consuming link. The cost of etching is second only to lithography, and its importance is increasing day by day. Thin film deposition is also a basic and important process. In order to realize the layered structure of large integrated circuits, it is necessary to repeat the process of deposition-etching-deposition.
With the development of international high-end mass-produced chips from 14nm to 10nm, and then to 7nm, 5nm or even smaller, the immersion mask aligner widely used in the market at present is limited by the wavelength of light, and its key dimensions cannot meet the requirements, so it is necessary to adopt multi-template technology. Using etching process to realize smaller size further enhances the importance of etching technology and related equipment.
Etching machine is one of the important equipment for chip manufacturing and micromachining. It uses plasma etching technology and uses active chemicals to etch microcircuits on silicon wafers. 7nm process is equivalent to one thousandth of the diameter of human hair, which is the minimum wiring spacing of integrated circuits that people can manufacture on a large production line, which is close to the limit of micromachining. Although there is still a gap between China's semiconductor equipment industry and international giants, we can see that the domestic semiconductor equipment industry has made a qualitative leap in terms of environmental drive, downstream demand and R&D capability.
Zhongwei company is mainly engaged in high-end semiconductor chip equipment, including semiconductor chip integrated circuit manufacturing, advanced packaging, LED production, MEMS manufacturing and other high-end equipment with micro technology. The company's plasma etching equipment has been specially used to process and manufacture integrated circuits and advanced packages of 65nm to 14nm, 7nm and 5nm for international first-line customers. Among them, 7nm/5nm etching technology is a scarce technology in China. The company's MOCVD equipment has been put into mass production on the production lines of leading customers in the industry, becoming the world's leading GaN-based led manufacturer.
Our customers include mainstream fabs and LED manufacturers at home and abroad. With the continuous improvement of the company's product performance, the recognition and richness of customers are also constantly improving. The main customers of the etching equipment produced by the company include TSMC, SMIC, UMC, Hynix, Changjiang Warehouse and so on. And photoelectric manufacturers Huacan Optoelectronics, Yang Can Optoelectronics and Sanan Optoelectronics. With the continuous development of Zhongwei company in the field of semiconductor chip equipment, the company's penetration rate in integrated circuit manufacturing, integrated circuit packaging and testing and LED industry has been continuously improved, and more and more international manufacturers have become the company's main customers. The 5nm etching machine developed by the company has passed the verification of TSMC. Prismo A7 equipment is in a leading position in the global gallium nitride-based LED MOCVD market, successfully surpassing traditional leading enterprises Veeco and Aixtron.
Zhongwei company's main business is the production and sales of etching equipment and MOCVD equipment, which is in the forefront of the domestic semiconductor equipment market. Comparable companies include international leading etching equipment LAM, leading MOCVD equipment Veeco, and two domestic semiconductor equipment companies, North Huachuang and Precision Electronics. In the etching equipment market, there is a big gap between Zhongwei Company and LAM Company. In the field of MOCVD equipment, Zhongwei Company has the same strength as Veeco. Domestically, Zhongwei Company and Precision Electronics are at the same level, second only to Beihuachuang, mainly because the company is a rising star of semiconductor chip equipment. Generally speaking, Zhongwei Company is in the first echelon of domestic semiconductor chip equipment.
In the first three quarters of 2020, the operating income was 65.438+0.48 billion yuan, up 265.438+0.3% year-on-year, and the net profit attributable to the owners of the parent company was 280 million yuan, up 654.38+0.05% year-on-year. Non-net profit was-45.473 million yuan, down 65.438+0.38 1% year-on-year. Among them, the non-recurring profit and loss in the first three quarters was 244 million yuan. Excluding government subsidies, the confirmed fair value change profit and loss is 65.438+0.55 billion yuan, which is mainly caused by the change in equity value of SMIC A shares invested by the company and the oversupply of LED chips. With the continuous decline of prices, downstream enterprises are facing the dual pressures of gross profit margin and inventory.
Zhongwei Company, the semiconductor chip etching equipment of Heima A-share listed company, has maintained a medium-term downward trend since it peaked in July 2020, with relatively few main chips. According to big data statistics, the main chip is about 2 1%, and the main control ratio is about 3 1%. In terms of trend judgment and long-short judgment, we can refer to the arrangement relationship between 15 and 45-day moving average, with 15 moving average as long-short reference in the short and medium term and 45-day moving average as long-short reference in the medium term.
