Modern technology development has made semiconductor manufacturing essential for advancing electronics industry development. Cheapest and smallest particles encountered during the manufacturing stage have the power to damage both the functionality of chips and their manufacturing outcomes. Cleanrooms have now established themselves as critical components for every semiconductor production facility.

A Clean Room is a room in which the concentration of suspended particles in the air is controlled. It should be constructed and used to minimize the introduction, generation and retention of particles in the room. Other relevant parameters such as temperature, humidity, pressure, etc. are required to be controlled. Air cleanliness refers to the extent of the amount of dust particles in the air in a clean environment, high dust concentration is low cleanliness, low dust concentration is high cleanliness.

Class C bioengineering Cleanroom is a clean level in the field of bioengineering based on air cleanliness, air pressure, air volume, temperature and humidity, noise, microbial content and other indicators. It is mainly used for clean operation areas of lower importance in the process of producing sterile drugs, such as the preliminary processing of cell culture, genetic testing and other links.

Clean Room refers to the air cleanliness to achieve the required level of space for human activities, its function is to control the particles (dust particles) of pollution to meet the production of precision products and scientific experiments to meet the requirements of the activities. Clean Room is not only control 'clean', different industries and sectors of temperature, humidity, lighting, noise, static electricity, micro vibration have considerable requirements of the multi-functional integrated whole.
