In today's era of rapid technological development, there is a key component called the "heart of modern industry", that is-the wafer (Wafer). As the core foundation of chips and semiconductors, wafers support the development of a series of cutting-edge technologies such as smartphones, computers and even artificial intelligence with their excellent performance.

From the perspective of raw materials, wafers are mainly made of ultra-pure monocrystalline silicon. This material is cut into thin sheets after complex pull growth and a series of precision machining steps to form an ideal platform for large-scale integrated circuit manufacturing. Each link requires a high level of technology and equipment investment to ensure that the final product quality meets international standards.

Understanding how a wafer is born is crucial. First of all, the silicon liquid in the molten state needs to be cooled and solidified into a cylindrical crystal; then it is precisely sliced, polished and polished according to the required specifications until the surface is smooth and flawless as a mirror. It will then go through multiple stages such as cleaning, coating, lithography, etching, and packaging tests before it can be officially put into use.

it is worth noting that there are many types of wafer products in the market, each with its own merits. for example, SOI (silicon on insulator) has the characteristics of lower power consumption and higher frequency response, which is suitable for wireless communication. However, GaN-on-SiC substrate has become one of the preferred schemes for power devices of new energy vehicles due to its advantages of high temperature and high pressure resistance. these differentiated designs can better meet the different needs of customers in specific application scenarios.

So where can you see the wafer? The answer covers almost all the internal structure of modern electronic products! Whether it is a light touch between the palm of the world of intelligent terminal equipment, there are a large number of microprocessor unit arrays hidden behind the screen of the intelligent terminal equipment, which are arranged in a neat and orderly manner to run computing tasks to ensure smooth operation experience. Or the data exchange hubs in the data center server cluster that operate silently are also inseparable from the high-performance computing capability to support the huge information flow transmission network architecture construction work.

Looking ahead, next-generation wafer technology research and development is moving towards smaller linewidth nodes, which will further release the potential of computing power while reducing energy consumption performance. However, at the same time, we must also face the following new challenges, such as how to overcome the quantum tunneling effect, which leads to the increase of leakage current.

When it comes to the factors to consider in entering this booming industry, it inevitably involves the scale of capital investment in the early stage, the evaluation of the return cycle, the planning of the length of the return cycle, the construction of long-term strategic partnership, the discussion, research, analysis and comparison, the selection of the optimal path to realize the vision blueprint of sustainable development goals, the drawing of the implementation of the implementation of the implementation of the promotion plan, the implementation of the follow-up, supervision and assessment mechanism, the establishment of continuous improvement, optimization and upgrading, and upgrading, and upgrading, the spiral development trend of the cycle, and the trend of the trend of the trend of ~
