Semiconductor workshop clean room

Abstract

The invention discloses a semiconductor workshop clean room, and relates to the technical field of clean rooms. The semiconductor workshop clean room comprises a clean working room, an air supply system, an air return system and a filtering system are arranged in the clean working room, the clean working room comprises a clean operation area and a processing service area, and a compartmentation area is arranged between the clean operation area and the processing service area; the compartmentation area comprises a vertical air supply area and a horizontal air supply area, a longitudinal air flow wall and a transverse air flow wall are formed in the vertical air supply area and the horizontal air supply area respectively, and an interval is formed between the longitudinal air flow wall and the transverse air flow wall, a vector air supply system and a one-way air supply system are arranged in the clean operation area, and a turbulent flow air supply system is arranged in the processing service area. The clean operation area and the processing service area achieve the purpose of limiting turbulent flow or vortex through the compartmentation area between the clean operation area and the processing service area and the air supply system, the air return system and the filtering system which are independent of each other, and therefore the purpose of improving the air cleanliness in the clean room is achieved.

Description

technical field [0001] The invention relates to the technical field of clean rooms, in particular to a clean room of a semiconductor workshop. Background technique [0002] Semiconductors refer to materials whose electrical conductivity is between conductors and insulators at room temperature, and are widely used in consumer electronics, communication systems, and medical instruments. Dust-free clean room, also known as clean room, clean room or dust-free workshop, can effectively control the indoor or factory air cleanliness, temperature and humidity, and air flow direction and other factors that affect the production process, and can meet the precision machinery industry, The semiconductor industry has strict requirements on the working environment. [0003] The existing authorized notification number is the Chinese patent CN103206101B, which discloses a clean room for semiconductor workshops, including a large clean space, which is equipped with a fresh air delivery syst...
