What is needed for the leap-forward progress of the domestic semiconductor material industry?

Today, in the past development, the semiconductor industry chain has become a complex system that needs support from multiple fields. Roughly speaking, materials, equipment, EDA and other fields are in the upstream of the semiconductor industry chain, and they are also an indispensable driving force for the continued development of the semiconductor industry.

As far as the field of semiconductor materials is concerned, according to the research report of Dongguan Securities, semiconductor materials are the most subdivided links in the semiconductor industry chain, and there are hundreds of subdivision industries. Divided by categories, semiconductor materials mainly include wafer fabrication materials and semiconductor packaging materials. In particular, the expansion of semiconductor manufacturing scale in recent years has made mainland China the fastest growing region for semiconductor materials.

But for the semiconductor material industry, there are still challenges. Especially for domestic semiconductor material manufacturers who started late, what progress is needed to achieve leapfrog development.

  The importance of Electronic materials to the semiconductor industry

The materials used in semiconductors are part of electronic materials. Conceptually, electronic materials refer to materials used in electronic technology and microelectronics technology, including dielectric materials, semiconductor materials, piezoelectric and ferroelectric materials, conductive metals and Its alloy materials, magnetic materials, optoelectronic materials, electromagnetic wave shielding materials and other related materials.

Specifically in the field of semiconductors, silicon wafers, high-purity chemicals, high-purity gases, photoresists, polishing liquids, targets, etc. are all well-known semiconductor materials.

In the final analysis, semiconductor materials are also a major field developed with the progress of process nodes, and as process nodes become more and more advanced, the level of semiconductor materials is required to be higher and higher, including cleanliness, purity, etc. If the semiconductor material grade does not meet the requirements, it will affect the performance, stability and yield of the final chip.

That is to say, the quality and level of these materials directly determine the performance of electronic components and complete machine products.

 Who guarantees the reliability of electronic materials?

Filters are one of the keys to ensuring the reliability of semiconductor materials.

Pall has been in the field of filters for 75 years. During these 75 years, with the increasing dependence of semiconductors on electronic materials, Pall has also started filtration research on semiconductor materials. According to Gong Zhihua, national sales manager of the electronic materials sector of Pall’s China Microelectronics Division, the filters produced by Pall have been used in the field of semiconductor materials for more than 30 years.

Filtration of silicon wafers, photoresists, wet electronic chemicals, and slurries is a key area of ​​focus for Pall. Among these different semiconductor materials, filters also play different roles.

In the production process of silicon wafers, from the start of crystal growth to the final cleaning process, Pall can provide BBU backflushing systems, high-efficiency slurry filters, high-precision gas filters, and high-precision chemical filters. A complete solution to safeguard the filtration needs of every step of wafer production.

For photoresists, Pall’s particle filters and ion purifiers can help remove particles and metal ions from raw materials (such as solvents, polymers, resins, etc.) used in photoresist formulations, while high-precision particle filters After the photoresist is synthesized, the particles can be further filtered to meet the filtering requirements of different dimensions.

In wet electronic chemicals, Pall has PTFE products ranging from microns down to 2nm, which can meet the precision required for the production of all chemicals today. According to reports, most of Pall’s PTFE membrane raw materials come from its own membrane factories, which further ensures the quality of its products.

In terms of slurry filtration, Pall can provide depth filtration products with a minimum precision of 50nm and membrane products. These filtration products can intercept large particles in the production process of slurry, reduce LPC, and reduce defects such as scratches at the chip production end. Pall hopes to ensure the longevity of electronic materials by providing better filtration.

With years of hard work in different materials, Pall’s filtration solutions have also been recognized by the market. It is understood that so far, Pall’s electronic material filters have accounted for 40% of the global share.

  Layout of Pall Electronic Materials Filters in China

For the rapidly developing Chinese semiconductor industry, the development of semiconductor materials has also begun to attract the attention of the industry, and has become one of the key directions for the development of the domestic semiconductor industry chain. With the support of national policies and the joint efforts of industry insiders, China’s electronic materials industry has developed vigorously in recent years, which has also promoted the growth of domestic demand for semiconductor material filtration solutions. However, the fact that the domestic material industry is facing is that the filtering products that can be provided in China are still in their infancy, and the relevant filtering solutions need to be improved. challenge.

To solve this problem, we must first understand the pain points of the market. Pall believes that with the continuous evolution of the process, the performance of the semiconductor materials used in it is also constantly improving. Therefore, being able to provide a complete electronic material filtration solution in a timely manner is a pain point in the current semiconductor material industry. In order to solve this pain point, Pall will upgrade its semiconductor material filtration products every 2-3 years, and launch a complete solution suitable for it.

In addition to timeliness, “production technology, application experience, safety of raw material supply, and cost are also the keys to developing electronic material filters,” added Gong Zhihua. From the perspective of the domestic semiconductor material market, the choice of relevant domestic manufacturers for semiconductor material filter suppliers depends more on their experience in this industry. Pall has 30 years of application experience in this field, and can help domestic related companies to improve the semiconductor material development system.

In order to meet the needs of local manufacturers in a timely manner, Pall has established a dedicated electronic material filtration team in China, including a sales team and a technical team, to serve the development of the domestic semiconductor material market. “Considering the situation of domestic customers, Pall has selected personnel with more than ten years of experience in semiconductors to form the current electronic materials team,” said Gong Zhihua: “In addition, Pall has also established laboratories in China. The laboratory can also help customers with application experiments to provide efficient and optimal filtration solutions.”

In order to further promote the development of localization and strengthen the supply of the industrial chain, Pall also joined the China Electronic Materials Industry Association to actively establish interactions with local customers.

In terms of establishing a domestic semiconductor material industry chain, Pall has also implemented its aspirations into practical actions—expanding production and transferring filters such as grinding fluids to domestic production are Pall’s layout for domestic electronic material filters. Pall hopes that through this plan, the company can help the development of China’s semiconductor material industry and contribute to the progress of the domestic semiconductor industry.

Epilogue

With the development of the domestic semiconductor industry, we have gradually uncovered some key technologies behind the semiconductor subdivision. And these areas that have not been paid attention to may be more important to the next development of the semiconductor industry.

Under such circumstances, companies like Pall, which have been working silently in the semiconductor industry segment for many years, have also received great attention in today’s semiconductor market.
