The photoresist is so short that it can be robbed! Concept stocks soar collectively, the localization of semiconductor materials shows up.

Today (March 23) A shares opened, photoresist plate rose strongly. As of press time, Jingrui shares, Guangxin Materials, Jiang Hua Wei, Optoelectronics, Glinda, a number of stocks rose by the daily limit, Nanjing University Optoelectronics, Rong Da photosensitive, powerful new materials, etc., rose one after another, up more than 10%.

On the news, it was reported on March 22 that there was a shortage of raw materials and full capacity in chip production, and it was difficult for enterprises to import photoresist. Through the visit, it was found that, according to customs officers, the amount of photoresist purchased by enterprises in the past was more than 100 kilograms each time, but recently, due to the shortage of raw materials, enterprises can only buy a small amount (10-20 kilograms) at a time.

Huatian science and technology personnel said that as she has worked in this industry for more than ten years, she has never encountered such a tense situation, especially in the area of photoresist, where suppliers used to come to the door, but now the situation is that manufacturers go to the supplier and work directly in the office of the supplier.

Semiconductor material domestic substitute for large space photoresist to meet the opportunity

According to SEMI's forecast, the global semiconductor material market will be 56.5 billion US dollars in 2021, and there is still a lot of room for improvement in China's share of production capacity. With the development of China's semiconductor industry, China's semiconductor material market is expected to reach US $10.4 billion in 2021, making it the second largest semiconductor material market in the world, but China's production capacity accounts for only 13% to 15%, so there is still a lot of room for improvement.

In addition, SEMI statistics show that from 2016 to 2019, the global market size of semiconductor photoresist increased from US $1.5 billion to US $1.8 billion in 2019, with a compound annual growth rate of 6.3%. According to this, it is predicted that the global market for semiconductor photoresist will be about US $1.9 billion in 2020.

At present, the global photoresist market is dominated by Japanese manufacturers, accounting for 80% of the market, with few price fluctuations. Subject to the development level of domestic photoresist technology, at present, the self-sufficient rate of domestic g-line and I-line photoresist is 20%, that of KRF photoresist is less than 5%, while ARF photoresist suitable for 12-inch silicon wafers basically depends on imports, and the localization of photoresist has a long way to go.

Huatai Securities said that taking Japan as a mirror, the focus of the semiconductor market has shifted to China, and the domestic semiconductor photoresist welcomes the development opportunity.

In the 1970s, as Japan became the focus of the global electronics industry and semiconductor market, Japanese enterprises seized the opportunity of the local industry to enter the photoresist market and became the leader in the photoresist field and continues to this day.

Today, China's local wafer manufacturing capacity continues to expand as it becomes the world's largest electronics industry and semiconductor consumer market.

According to SEMI's forecast, China's wafer production capacity will reach 4 million pieces per month in 2020, and the production capacity layout will fully cover the logical process, memory, characteristic process and other areas, which is expected to lead to a continuous increase in semiconductor photoresist demand. According to Zhiyan Consulting, the market space of semiconductor photoresist in mainland China will be close to 5.5 billion yuan in 2022, double that in 2019.
