|1. (WO2017032247) MANUFACTURING METHOD FOR MAGNETIC MASK PLATE FOR EVAPORATION|
|Applicants:||KUN SHAN POWER STENCIL CO., LTD.
|Title:||MANUFACTURING METHOD FOR MAGNETIC MASK PLATE FOR EVAPORATION|
A manufacturing method for a magnetic mask plate for evaporation. The method comprises: S1: manufacturing a metal supporting layer; S2: covering the surface of the metal supporting layer with a film; S3: performing exposure on a photoresist film layer; and S4: performing developing on the photoresist film layer. According to the magnetic mask plate manufactured by using the method, an organic mask layer forming the mask plate can be made to be very thin, further, the width of an opening is made to be smaller, so that the final magnetic mask plate can be used for evaporating, to form OLED products with higher resolution.
