In the semiconductor device workshop, due to the dust adsorbed on the chip, the yield of IC, especially VLSI, will be greatly reduced. IC production workshop operators wear clean work clothes, if the human body with static electricity, it is very easy to absorb dust, dirt, etc., if these dust, dirt is brought to the operation site, it will affect the product quality, deteriorate product performance, greatly reduce the IC yield. If the radius of the adsorbed dust particles is greater than 100 μ M the line width is about 100 μ The thickness of the film is 50 μ When m is lower, the product is most likely to be scrapped.

Therefore, it is necessary to establish the electrostatic protection system in the process of IC Processing and packaging! IC packaging production line has more strict requirements on static electricity. In order to ensure the normal operation of the production line, carry out the overall decoration of anti-static building materials for the clean workshop, and take hardware measures such as equipping all personnel in and out of the clean workshop with anti-static clothing, the packaging enterprise can formulate enterprise standards or specific requirements on anti-static according to the relevant national standards and the actual situation of the enterprise, To cooperate with the normal operation of IC packaging production line
