Abstract
The invention discloses a semiconductor UV viscous reducing film preparation device, which is characterized in that it is provided with: a UV viscous reducing glue production mechanism for processing and manufacturing antistatic UV viscous reducing glue; a UV viscous reducing glue coating mechanism, which is set At the bottom of the UV viscosity-reducing glue production mechanism, the UV viscosity-reducing glue coating mechanism is used to coat the surface of the release film layer with the antistatic UV viscosity-reducing glue manufactured by the UV viscosity-reducing glue production mechanism; The conveying mechanism is arranged at the bottom end of the UV viscous reducing glue coating mechanism, and the conveying mechanism is used to transport the release film layer to the UV visbreaking glue coating mechanism for coating. In the process of stirring the UV mucous membrane reducing raw materials, according to the different chemical components of each material in the raw materials, it can be put in batches and in different periods to ensure that the reaction time of each reactant entering the raw material mixing tank is similar. Then obtain the UV mucous-reducing glue with more uniform antistatic distribution.
Description
technical field [0001] The invention relates to the technical field of semiconductor protective films, in particular to a preparation method and a preparation device of a semiconductor UV mucous-reducing film. Background technique [0002] In the process of semiconductor processing, semiconductor wafers are often cut and polished. In order to reduce the defect density of silicon thin layers in semiconductors, UV-viscosity-reducing protective films are often used. UV-viscosity-reducing protective films are not treated by UV light. Its adhesion is very strong, which can ensure the stability of the product during the production process. When it is necessary to remove the UV mucous reducing film, it only needs to be treated with UV light to make it almost non-sticky, which is very easy. Being peeled off, there will be no damage to the product and no residual glue on the product. [0003] The common UV adhesive film on the market is usually composed of three layers: PVC protecti...
