Immersion lithography machines can theoretically manufacture 2nm chips, and cost is the only obstacle
Although immersion lithography has been able to fabricate 2 nm wafers in principle, the main problem it faces is the high cost of **.
Some time ago, the immersion lithography technology realized the 2 nm process in principle, which aroused heated discussions in the industry and netizens. Immersive lithography techniques are taken lightly! This method is based on the so-called"Multiple**"In principle, a wafer of 2 nm or higher is possible. Is this trick good? Will it work? Is it expensive? Let's take a look!
1. What is the basic theory of the multiple ** method? What is the basis for obtaining a higher resolution?
Multiple** is to decompose the original single paragraph** into several paragraphs, such as 10 paragraphs or 20 paragraphs. This method can reduce the difficulty of a single exposure, and can improve the clarity of the image and reduce the number of computing nodes. This principle is like writing one word at a time, and it will always be easier than typing out the entire sentence at once.
2. But the biggest problem with multiple exposures is that the cost is too high, what do you say?
First of all, the calibration of each one is very accurate, or it is wrong. This requires very delicate instrumentation to ensure accurate and repeatable positions, and it can be costly.
Secondly, the demand for photoresist in multi-layer stacks is larger, and the requirements for photoresist are also higher.
Third, the issue of income can become the biggest obstacle because of the rising risks. If something goes wrong, the damage can be significant. This is a huge challenge for output management.
How can we achieve a balance between economy and technology? What is the future of virtual lithography?
Every technological advancement has its own limitations, but they are flexible limits that can be surpassed on an ongoing basis. But the problem is that the higher you go, the more expense and difficulty you have. To achieve this goal, it is necessary to strike a balance between economic and social benefits, otherwise it will be very difficult.
If an enterprise wants to achieve an effective combination of science and technology and capital, it must rely on its own continuous innovation and strong support. Only in this way can the bottleneck of the development of the immersion lithography process be broken, otherwise it will be stuck by the process bottleneck of 7 nm and beyond.
4. Can immersive lithography achieve 2nm process? Industry insiders and netizens have different opinions on this.
On the Internet, the discussion about this matter quickly heated up. Some netizens said that there will always be a way to lithography and it is expected to be completed within a few years; Some netizens said that the cost of doing so is very high and requires a subsidy from **; Some people also think that it is necessary to reduce the frequency of exposure as much as possible, starting with materials and equipment. In general, we are all looking forward to the development of technology.
Development driven by science and technology and economy.
From this point, it can be seen that there are certain physiological limitations in the development of every technology. However, the main factor hindering scientific and technological progress is that in order for science and technology to continue to progress, it is necessary to have policies that combine scientific and technological progress with capital investment. This is a universal law of technological development.
Enterprises and enterprises should strengthen the dual promotion of science and technology and capital to benefit mankind, break the new field of lithography in an immersive way, and move from theory to practice!
The innovation of science and technology is also inseparable from the support of funds, can immersion lithography break the limitations of existing processes?
Can immersion lithography withstand the multiplicity of processes at 2 nm and above**? This is an issue that requires our continued attention and reflection. Although scientific and technological innovation is very important, it is impossible to complete without sufficient financial support, and it is difficult to break through its own limitations. We'll see!
