【Chemical machinery and equipment network industry dynamics】Recently, the voice of "semiconductor" continues to rise, and the market is constantly paying attention to the development trend and trend of the entire industry, which makes the editor also have an in-depth understanding of China's achievements in the value chain of silicon wafers, electronic special gases, etching and deposition, chemical mechanical polishing, etc.
, as well as the advantages and disadvantages
of semiconductor manufacturing, wafer manufacturing, lithography equipment, process devices and so on.

Not to mention, a history of the rise of "blood and sweat" is more difficult than the environmental protection industry, but there is no lack of commonalities
between the two.
Of course, today's talk is not about this topic, but about the pollution control
of the semiconductor industry.

That's right, in the "thrilling" semiconductor multi-party game, carbon emission reduction cannot be "released"
.
Like all industries, semiconductor companies also need to make efforts in carbon peak and carbon neutrality, be technology-oriented, take zero carbon as the goal, and truly become an "excellent representative"
of high-tech companies in the new era.

In other words, because the pollutants such as industrial wastewater, industrial waste gas, and industrial waste residue generated by the semiconductor industry have industry characteristics, the difficulty of treatment is higher than that of the general "industrial three wastes", and it is more necessary to work pollution reduction and carbon reduction
.
Compared with the first-generation semiconductor industry, the third-generation semiconductor industry with silicon carbide and gallium nitride as representative materials actually occupies a relatively advantageous position
.

It is reported that gallium nitride (GaN) and silicon carbide (SiC) can reduce energy loss by more than 50% and reduce equipment volume by more than 75% compared with silicon devices, which is one
of them.
Second, the third-generation semiconductor industry can realize a low-carbon strategy for the whole life cycle from design to manufacturing, to packaging and testing, and application in the era of "dual carbon", or carbon emissions can be controlled
.

After all, the semiconductor industry has always been a "big consumer" of resources, with a huge demand for electricity and a lot of water demand
.
Taking the more famous TSMC as an example, its report clearly stated that TSMC's electricity consumption in 2020 was 16.
9 billion kWh, exceeding the electricity consumption of the entire Taipei City, equivalent to nearly 6%
of Taiwan's annual electricity consumption.
Moreover, this figure is expected to rise to about
7% this year.

In terms of water consumption, public data shows that the daily water consumption of TSMC's three plants exceeds 190,000 tons, and TSMC's water consumption in 2020 is about
70 million tons.
Of course, the good news is that TSMC said that it has achieved 86% of wastewater recycling, at least to a large extent to avoid the contradiction
between industrial water and agricultural and domestic water.

In fact, this is also a common phenomenon in the industry, TSMC is by no means the only semiconductor company
that strives to save water, save energy, reduce carbon and reduce emissions.
Intel, for example, has pledged to recycle 100% of its water by 2025 and use 100% clean energy by 2030; SK hynix has enabled the life cycle assessment system and controlled the BOD within 10% of the national standard; and Infineon, which has pledged to become carbon neutral by 2030, among others
.

It can also be seen that this will be the norm in the semiconductor industry in the future, and semiconductor companies and companies in all walks of life will face "carbon anxiety", which is the consistent goal
under the tide of global emission reduction.
Throughout the "net zero" path of the semiconductor industry, in addition to the necessary terminal waste gas, waste water, solid waste disposal, the priority of energy conservation and emission control is also very high, including clean energy power system conversion, product energy efficiency improvement, resource recycling and reuse, low-carbon data center construction, intelligent upgrading and other means are still the mainstream
.
