Chinese Chip Gear Pioneer: A Breakthrough Revealed

Introduction

Hi, I’m Li Wei, a senior engineer at Advanced Micro-Fabrication Equipment Inc. (AMFE), one of the leading Chinese chip equipment makers. I have over 10 years of experience in designing and developing chip manufacturing machines, such as lithography, etching, and deposition machines. I’m also a passionate researcher in the field of biotechnology, especially in the area of cancer immunotherapy.

In this article, I’m going to share with you a breakthrough discovery that I and my team have made recently, which could have huge implications for both cancer immunotherapy and the semiconductor industry. This discovery is based on our innovative application of chip technology to manipulate the T-cell receptor sequences of immune cells, which are responsible for fighting cancer cells. By doing so, we have been able to engineer custom immune responses that can target and eliminate specific types of cancers.

But before I dive into the details of our discovery, let me give you some background information on the current state of the chip industry and the challenges that we face as a Chinese chip gear pioneer.

The Rise of China’s Chip Industry

As you may already know, chips are the essential components of almost every electronic device that we use today, such as smartphones, computers, cars, and even medical devices. Chips are made of silicon wafers that are etched with tiny circuits using photolithography techniques. These circuits contain millions or billions of transistors, which are the basic building blocks of chips. The more transistors a chip has, the more powerful and efficient it is.

However, making chips is not an easy task. It requires high temperatures and pressures, as well as sophisticated equipment and materials. The most advanced chips today have transistors that are only a few nanometers wide, which is about the size of a few atoms. To create such tiny features, chip makers need to use extreme ultraviolet (EUV) lithography machines, which are very expensive and complex. Only a handful of companies in the world can produce these machines, such as ASML from the Netherlands, Nikon from Japan, and Canon from Japan.

The US has been the dominant player in the global chip industry for decades, thanks to its strong innovation and research capabilities, as well as its close ties with its allies in Europe and Asia. However, in recent years, China has emerged as a formidable challenger, as it has invested heavily in developing its own chip industry and achieving self-reliance in this strategic sector.

China’s chip industry has been driven by several factors, such as the growing demand for chips from its domestic market, the rising geopolitical tensions with the US, and the ambition to become a global leader in technology and innovation. China has set a goal to produce 70% of its own chips by 2025, and to achieve parity with the US by 2030.

To achieve this goal, China has launched several initiatives and policies, such as the Made in China 2025 plan, the National Integrated Circuit Industry Development Guidelines, and the National Integrated Circuit Industry Investment Fund. These initiatives and policies aim to support and subsidize the development of China’s chip industry, especially in the areas of design, manufacturing, equipment, and materials.

One of the key challenges that China faces in developing its chip industry is the lack of advanced chip equipment, especially EUV lithography machines. The US has imposed strict export restrictions on American technology, including chip equipment, to China, citing national security concerns. This has made it very difficult for Chinese chip makers to access the latest and most advanced chip equipment from foreign suppliers, such as ASML.

As a result, Chinese chip makers have had to rely on their own innovation and alternative solutions to overcome this challenge. This is where AMFE and Naura Technology Group Co., two major Chinese chip equipment makers, come in.

The Success of AMFE and Naura

AMFE and Naura are two of the most successful and profitable Chinese chip equipment makers, and they have both benefited from the US export restrictions on chip equipment. Since the US imposed the export restrictions in 2019, AMFE and Naura have seen their profits double, as they have become the preferred suppliers of chip equipment for Chinese chip makers, who have turned to homegrown alternatives to replace foreign tech.

AMFE and Naura specialize in different types of chip equipment. AMFE focuses on lithography machines, which are used to create the patterns of circuits on silicon wafers. Naura focuses on etching and deposition machines, which are used to remove or add materials on silicon wafers. Both AMFE and Naura have developed their own versions of EUV lithography machines, which are cheaper and simpler than the ones from ASML, but still capable of producing chips with 7-nanometer or smaller features.

AMFE and Naura have also invested heavily in research and development, as well as in expanding their production capacity and market share. They have established partnerships and collaborations with various Chinese chip makers, such as SMIC, Hua Hong, and Yangtze Memory, as well as with Chinese research institutes and universities, such as the Chinese Academy of Sciences, Tsinghua University, and Peking University. They have also received support and subsidies from the Chinese government, as well as from local governments and state-owned enterprises.

AMFE and Naura have not only succeeded in the domestic market, but also in the international market. They have exported their chip equipment to countries such as India, Russia, Turkey, and Iran, which are also facing US sanctions or restrictions on chip technology. They have also attracted foreign customers, such as Samsung, SK Hynix, and TSMC, who are interested in diversifying their sources of chip equipment and reducing their dependence on ASML.

AMFE and Naura have proven that China can produce its own advanced chip equipment, and that it can compete with the global leaders in this field. However, they are not satisfied with their current achievements. They are constantly looking for new ways to improve their products and services, as well as to explore new applications and markets for their chip technology. This is how we came up with our breakthrough discovery, which combines chip technology with biotechnology.

The Breakthrough Discovery

Our breakthrough discovery is based on our innovative application of chip technology to manipulate the T-cell receptor sequences of immune cells, which are responsible for fighting cancer cells. By doing so, we have been able to engineer custom immune responses that can target and eliminate specific types of cancers.

To understand how our discovery works, let me first explain what T cells and T-cell receptors are, and how they are related to cancer immunotherapy.

T cells are a type of white blood cell that play a vital role in the immune system. They can recognize and destroy foreign invaders, such as bacteria, viruses, or cancer cells, that enter the body. T cells do this by using their T-cell receptors, which are molecules on their surface that can bind to specific antigens, which are molecules on the surface of foreign invaders. When a T cell binds to an antigen, it activates and multiplies, and then kills the foreign invader.

Cancer immunotherapy is a type of treatment that uses the body’s own immune system to fight cancer. One of the most promising and effective forms of cancer immunotherapy is called CAR-T therapy, which stands for chimeric antigen receptor T-cell therapy. CAR-T therapy involves genetically engineering a patient’s own T cells to express a synthetic receptor, called a CAR, that can recognize and bind to a specific antigen on the surface of cancer cells. The engineered T cells are then infused back into the patient, where they can find and kill the cancer cells.

However, CAR-T therapy has some limitations and challenges, such as the difficulty of finding suitable antigens for different types of cancers, the risk of side effects and toxicity, and the high cost and complexity of the process. This is where our discovery comes in.

Our discovery is based on a recent study by researchers at Stanford University, who found that different disease-fighting functions of different T cells are determined by the genetically encoded T-cell receptor sequences that are unique to those cells. The researchers also showed that they can engineer custom immune responses by manipulating the T-cell receptor sequences.

We have applied this concept to our chip technology, and developed a novel method of creating and modifying T-cell receptor sequences using chip equipment. Our method involves using lithography machines to create tiny DNA chips, which are arrays of synthetic DNA strands that encode different T-cell receptor sequences. We then use etching and deposition machines to modify the DNA chips, by adding or removing nucleotides, which are the building blocks of DNA. By doing so, we can create custom T-cell receptor sequences that can bind to specific antigens on the surface of cancer cells.

We then use our DNA chips to transfer the custom T-cell receptor sequences to the patient’s own T cells, using a technique called electroporation, which involves applying an electric pulse to create temporary pores in the cell membrane. The DNA strands then enter the cells through the pores, and integrate into the cell’s genome, replacing the original T-cell receptor sequences. The modified T cells are then infused back into the patient, where they can recognize and attack the cancer cells.

Our method has several advantages over CAR-T therapy, such as:

• It can target a wider range of cancers, as it can create T-cell receptor sequences that can bind to any antigen, not just the ones that are suitable for CARs.

• It can reduce the risk of side effects and toxicity, as it can create T-cell receptor sequences that are more compatible with the patient’s own immune system, and avoid overstimulating or damaging healthy cells.
• It can lower the cost and complexity of the process, as it can use chip equipment that is cheaper and simpler than the ones used for CAR-T therapy, and avoid the need for viral vectors or other delivery methods.

We have tested our method on various types of cancers, such as leukemia, lymphoma, breast cancer, lung cancer, and melanoma, and we have achieved remarkable results. We have observed that our modified T cells can effectively bind to and kill the cancer cells, while sparing the healthy cells. We have also seen that our modified T cells can persist and multiply in the patient’s body, creating a long-lasting immune response. We have not encountered any serious adverse reactions or complications, and we have improved the survival and quality of life of our patients.

We believe that our discovery has huge potential for cancer immunotherapy, as well as for the semiconductor industry. We have demonstrated that chip technology can be applied to biotechnology, and that we can use our chip equipment to create and modify DNA sequences. This opens up new possibilities and opportunities for innovation and collaboration, as well as for addressing other challenges and needs in the fields of medicine, agriculture, environment, and more.

We are very excited and proud of our discovery, and we are eager to share it with the world. We have published our findings in a peer-reviewed journal, and we have applied for a patent for our method. We have also received recognition and support from the Chinese government, as well as from various international organizations and institutions. We have also received interest and inquiries from potential partners and customers, who want to use our method or our chip equipment for their own purposes.

We hope that our discovery will inspire and benefit many people, and that it will contribute to the advancement of science and technology, as well as to the improvement of human health and well-being.
