Shengong Co., Ltd.: the company's 8-inch semiconductor silicon polishing wafer currently has a production capacity of 8000 pieces per month.

On August 12, Shengong said on the interactive platform that the company had opened the production line for polishing silicon wafers, the 8-inch semiconductor silicon wafer polishing project was carried out in an orderly manner, and equipment commissioning, process experiments and customer certification were carried out on Synchronize. The equipment has a production capacity of 50000 pieces per month and is currently produced on a scale of 8000 pieces per month.

In terms of monocrystalline silicon materials, Shengong large diameter monocrystalline silicon material business plate covers all products from 14 inches to 19 inches, which is mainly sold to silicon parts processing plants in semiconductor powers and regions such as Japan and South Korea, such as Mitsubishi Materials, CoorsTek, SK Chemistry, Hana Materials and other semiconductor materials industry enterprises. The product has international first-class competitiveness, is in the world advanced level in terms of technology, quality, production capacity and market share, and is also the company's main source of business income.

Among the existing specification products of Shengong Co., Ltd., the proportion of products with more than 15 inches is increasing year by year, because with the increase of the cavity size of the etching machine, the size of the upstream etching material is also increasing. The advantages of Shengong shares in the technology, cost and quality control of large-diameter products prompt customers to prefer this part of the order to Shengong shares. The company's sales revenue continues to rise, on the one hand, due to the continuous rise of the prosperity of the semiconductor industry, on the other hand, it is also due to the company's process reserves, equipment upgrading and other work to the correct direction of large-scale development in advance.

In 2020, after the research and development team of Shengong Co., Ltd. successfully grew a single crystal with a diameter of 22 inches, it began to tackle the key problems of polycrystalline silicon parts with a diameter of more than 22 inches in 2021, obtained a certain amount of test data, and continued to invest in research and development; at the same time, the company carried out the basic process research and development of polycrystalline parts, completed the initial process and small batch production, and the material purity basically conformed to the design value.

In terms of silicon electrodes, the main customers of Shengong shares have two categories: the first kind of customers are domestic etching machine manufacturers; the second kind of customers are domestic IC terminal manufacturers. Through cooperation with domestic well-known etching machine manufacturers, the company has obtained small batch orders. As for the customers of IC manufacturers, after the development of the market in 2020, the company has received bulk orders for 8-inch silicon electrodes, and will focus on promoting the certification of 12-inch customers in 2021. Because the 12-inch etching process is more than 8-inch steps and consumes more silicon electrodes, it is a core consumption component, so the customer evaluation is more cautious and the evaluation cycle is relatively longer. the company expects that evaluation orders can be gradually converted into small batch orders, thus gradually opening up the market. Silicon parts business has improved the company's original single sales model of relying on overseas markets and expanded the new domestic market.
