When talking about the importance of quality control in clean rooms, we cannot fail to notice the challenge of high-tech to cleanliness in the new century.

   According to Yang Zhenning's judgment at the 2001 China Association for Science and Technology Annual Conference, he believes that in the next three or four decades:

①chip is widely used;

② extensive development of medicine and drugs;

③These three aspects of bioengineering will become the locomotive of scientific and technological development. That is to say, this is the three strategic directions for the development of science and technology in the next three or four decades.

In the above three areas of the product, if pollution enters, it can constitute obstacles, short circuits, sources of impurities and potential defects. However, as far as the level of human development is concerned today, technology has improved, equipment has improved, and people's knowledge has improved. However, the environment has only regressed, air quality has deteriorated, and pollution has increased. Therefore, in order to enter the strategic direction of the three major technologies, in addition to the process itself, it is important to create a clean and indoor micro-environment to the cleansing challenge.

   It can be seen that there is a close relationship between clean technology and the three strategic directions.
