As the main consumables of the semiconductor industry, the silicon wafer industry benefits from the expansion of wafer factories under the tide of core shortage. After Hangzhou Lion Electronics Co.Ltd(605358)
domestic semiconductor silicon wafer accelerated import
The latest annual report shows that National Silicon Industry Group Co.Ltd(688126) achieved an operating revenue of 2.467 billion yuan in 2021, with a year-on-year increase of 36.19%; The net profit was 146 million yuan, a year-on-year increase of 67.81%; The net profit after deducting non-profit was -132 million yuan, and the loss reduction rate reached 53.09%.
In addition, from January to February this year, National Silicon Industry Group Co.Ltd(688126) achieved an operating revenue of about 511 million yuan, a year-on-year increase of about 51%; The non net profit deducted was about – 8.06 million yuan, a decrease of about 74% over the same period of last year The output and sales volume of National Silicon Industry Group Co.Ltd(688126) products continued to increase.
Recently, Hangzhou Lion Electronics Co.Ltd(605358) also disclosed that the net profit in 2021 doubled to 600 million yuan, and the net profit attributable to the parent company in the first quarter of 2022 was 238 million yuan, a year-on-year increase of about twice.
Benefiting from the strong demand in the semiconductor market and the rising production capacity, the business income of National Silicon Industry Group Co.Ltd(688126) 200mm and 300mm silicon wafers increased, and the gross profit margin increased. However, 300mm semiconductor silicon wafers still failed to make a profit due to the huge investment in fixed assets and R & D in the early stage. In terms of business, semiconductor silicon wafers of 200mm and below are still the main part of National Silicon Industry Group Co.Ltd(688126) revenue, accounting for more than half. The revenue of 300mm semiconductor silicon wafers doubled. The production line of 300000 pieces / month was built, and the gross profit margin increased by 28.65 percentage points year-on-year.
During the reporting period, National Silicon Industry Group Co.Ltd(688126) achieved a total shipment of more than 4 million pieces in history, and the certification cycle began to shorten, which was conducive to accelerating the introduction of customers. The company has realized the batch supply of 300mm semiconductor silicon wafers for 14nm process node applications; And the development and verification of 300mm semiconductor silicon wafer for 19nmdram, making breakthrough progress; It has passed the certification of 300mm polishing wafer for 64 layer and 128 layer 3dnand applications, and realized mass supply.
At present, the size of semiconductor silicon wafers commercially supplied by the semiconductor industry ranges from 100mm to 300mm, of which 300mm semiconductor silicon wafers occupy the mainstream position, accounting for nearly 70% of the shipping area. The most advanced logic product process technology node in the world is 5nm, but Chinese chip manufacturing enterprises still focus on 14nm, 28nm and above processes. In contrast, National Silicon Industry Group Co.Ltd(688126) can supply various sizes of semiconductor silicon wafers from 100mm to 300mm, which solves the problem of “neck” in the supply of 300mm large silicon wafers in China.
build a large silicon wafer industry ecology
Relatively speaking, National Silicon Industry Group Co.Ltd(688126) in addition to the development of 300mm, the capacity utilization rate of 200mm and below products (including SOI silicon wafer) occupying the main position continues to remain high, and the 200mm epitaxial wafer expansion plan for automotive electronic applications has been launched to meet the growing market demand of downstream customers.
It is understood that generally, the larger the size of silicon wafer, the lower the sharing cost. However, considering that most of the equipment is depreciated, the chip manufacturing cost corresponding to semiconductor silicon wafer of 200mm and below is often low and has high stability. It is mainly used in power devices, power managers, nonvolatile memory, MEMS, display driver chips and fingerprint identification chips. The terminal application fields are mainly mobile communication, automotive electronics, Internet of things, industrial electronics, etc, The growth is relatively stable.
According to National Silicon Industry Group Co.Ltd(688126) strategic planning, the company aims to achieve “one-stop” silicon material supply, and continue to develop 300mm high-end silicon-based materials, piezoelectric thin film materials, other heterogeneous integrated compound thin film materials and other characteristic products on the basis of existing 300mm semiconductor silicon wafers and 200mm and below semiconductor silicon wafers (including SOI silicon wafers); It will also open up the upstream and downstream joint R & D and product certification links of the large-size silicon wafer industry chain, establish, intervene in the R & D and production of upstream key process materials and parts, and develop SOI silicon material ecosystem, so as to open space for the development of the company in depth and breadth.
In February this year, National Silicon Industry Group Co.Ltd(688126) as a limited partner, invested 400 million yuan in Guangzhou Xinrui photomask Technology Co., Ltd. to build an advanced photomask production line for processes of 40-28nm and above, so as to solve the problem that there is no local supplier of commercial advanced photomask in China at present; Last September, the company invested 20 million yuan in Nanjing Jingsheng Equipment Co., Ltd., a supplier of semiconductor crystal drawing furnace equipment.
semiconductor silicon chips will still be in short supply
According to SEMI statistics, from 2016 to 2021, the sales of semiconductor wafers in Chinese mainland increased from $500 million to US $1 billion 656 million, with an average annual compound growth rate of 27.08%, which is far higher than the average annual compound growth rate of the global semiconductor silicon wafers during the same period. On the other hand, global wafer factories have also entered a period of rapid production expansion. By the end of 2021, 19 high-capacity chip manufacturing lines in the world have entered the construction period, and another 10 chip manufacturing lines will start construction in 2022
National Silicon Industry Group Co.Ltd(688126) it is estimated that under the background of limited market supply and new production capacity, the semiconductor silicon wafer industry is ushering in a new round of market opportunities in which supply exceeds demand.
Earlier, Hangzhou Lion Electronics Co.Ltd(605358) board secretary Wu nengyun also told reporters that benefiting from the development of clean energy such as photovoltaic and wind energy, as well as the strong demand for terminals such as new energy vehicles and industrial automation control, it is expected that there will be strong demand for semiconductor silicon chips in the next 3-5 years. It is understood that overseas peers have arranged orders until 2026.
National Silicon Industry Group Co.Ltd(688126) also started to further expand production. On December 14 last year, the fixed increase of National Silicon Industry Group Co.Ltd(688126) 5 billion yuan was approved. The raised investment will be invested in 300mm high-end silicon wafer R & D and advanced manufacturing projects. After the completion of the project, the total production capacity will reach Shanghai Pudong Development Bank Co.Ltd(600000) pieces / month, and a 300mm high-end silicon base material R & D pilot line with an annual production capacity of 400000 pieces will be built. During the reporting period, the company has basically completed the development of corresponding 300mm polishing wafer substrate products.
The fixed increase was also subscribed by 18 institutions such as national integrated circuit industry investment fund phase II, noan fund and Three Gorges capital, with an issue price of 20.83 yuan / share. However, National Silicon Industry Group Co.Ltd(688126) shares have fallen since the completion of the fixed increase in February.
