Sanchao New Materials Focuses On Electroplating Diamond Wire Products

The board of directors of Nanjing Sanchao New Materials Co., Ltd. issued an announcement on February 16. The announcement stated that the company issued the "About Nanjing Sanchao New Materials Co., Ltd.'s application to Notice of Opinions of the Examination Center for the Issuance of Stocks by Specific Objects”, the Shenzhen Stock Exchange’s issuance and listing review agency reviewed the company’s application documents for issuing stocks to specific objects, and believed that the company met the issuance conditions, listing conditions and information disclosure requirements.

Tongbi Finance understands that the company is a high-tech enterprise specializing in the R&D, production and sales of diamond tools, and is committed to becoming a domestic leading supplier of precision superhard material products with international influence.

Due to its advantages in cutting efficiency, material loss, environmental protection, product quality, and operating costs, diamond wire has basically replaced traditional cutting technologies in the fields of sapphire squaring and slicing, and square silicon core cutting; in the silicon squaring and truncation market It has developed into a mainstream process; it is rapidly replacing traditional cutting technology in markets such as monocrystalline silicon slicing; there have been certain technological breakthroughs in the field of polysilicon slicing, and with technological progress, it is expected that the penetration rate will gradually increase in the next few years.

my country's photovoltaic industry is developing rapidly, especially the middle and lower reaches of the photovoltaic industry chain have relatively large production capacity. According to the statistics of CPIA (China Photovoltaic Industry Association), in 2015, the production of silicon wafers, cells and modules in mainland my country accounted for 78.05%, 68.33% and 76.92% of the global total production. According to the data of the National Energy Administration, my country's new installed capacity in 2015 was 15.13GW, accounting for about 29.90% of the world's newly installed capacity. my country has developed into the world's largest producer of photovoltaic products and the largest photovoltaic market.

Due to the rapid expansion of production capacity in the sapphire industry in recent years, the price of sapphire has fallen sharply recently. At present, the sapphire substrate market is growing steadily, and the non-sapphire substrate market is in the stage of exploration and development, and has already been used to some extent. However, the market with large usage such as mobile phone screens has not yet achieved substantial breakthroughs. Considering that sapphire has the advantages of high hardness and infrared light transmission, its application in consumer electronics still has great potential.

Diamond is one of the most promising new-generation semiconductor materials. Its thermal conductivity and bulk material mobility are the highest in nature, and it has great application potential in the field of making power semiconductor devices. At present, countries around the world are stepping up the research and development of diamond in the semiconductor field. Among them, Japan has successfully developed an ultra-high-purity 2-inch diamond wafer mass production method, and its storage capacity is equivalent to 1 billion Blu-ray discs. As my country speeds up the promotion of key technological breakthroughs, functional diamond materials will transform from the laboratory stage to commercialization. We believe that artificial diamonds are not only cultivated diamonds, but are expected to enter the field of next-generation semiconductor materials.

As a new cutting technology that has emerged in recent years, diamond wire cutting technology has the huge advantages of fast cutting speed, low single-wafer consumables, and high wafer yield, which can greatly reduce the production cost of silicon wafer manufacturers. Before 2014, diamond wire suppliers with international competitive advantages were mainly concentrated in Japan, and domestic manufacturers caught up, gradually seized the market share of Japanese manufacturers, and completed import substitution. Diamond wire is the main material for silicon wafer cutting, and the demand for silicon wafer cutting accounts for more than 90%. In 22 years, with the increase in downstream installed capacity, the demand for silicon wafers has increased, and silicon raw materials have gradually returned to rationality. The profitability of diamond wire is expected to improve .

Looking at China from the upstream, my country monopolizes 95% of the world’s industrial diamond manufacturing. At present, industrial diamond single crystal + micropowder is nearly 15 billion carats, and it has the power to formulate the rules of the global industrial diamond industry and product pricing; the midstream is due to the high hardness and high temperature resistance of industrial diamond. Performance, made into grinding wheels, cutting wires, knives and other products in various forms, widely used in downstream oil drilling, stone cutting, photovoltaic cutting and other markets, with a wide range of applications and many application scenarios.

At present, industrial diamond is mainly prepared by high temperature and high pressure method, and the products are suitable for various types of drilling and cutting tools; CVD industrial diamond is expected to be used in semiconductor substrates, There are many applications in wafer preparation, infrared optical windows, and weaponry.

At present, the annual market demand for industrial diamond is about 4.5 billion yuan, of which construction stone demand accounts for 50% (about 2.2 billion yuan), photovoltaic/high-end manufacturing/consumer electronics account for 28% (about 1.3 billion yuan), and resource mining accounts for 17% (about 2.2 billion yuan). About 800 million yuan), in the later stage, with the "automobile + N" high-end manufacturing market, the demand for superhard tools/micro-drills will increase, the "green power" photovoltaic track will promote the rapid increase in diamond wire cutting, and sapphire substrates will continue to benefit from rising consumer electronics. In 2025, the demand for industrial diamonds will be 8.8-11.4 billion yuan, with a compound growth rate of 18%-26%. 2) Future semiconductor + military industry, materials leading change: CVD industrial diamond is expected to be used in semiconductor heat sinks and wafer manufacturing due to its excellent properties such as high temperature resistance, high radio frequency, and high pressure resistance, and in military missile fairings, Infrared optical windows and bulletproof fields also have great application space.

Judging from the company's financial data in the past five years, the total operating income of the three years has increased year-on-year, and the increment is good; the net profit attributable to the parent has performed better in the past five years; Poor, poor profitability.
