Abstract

The embodiment of the invention provides a mask device and a sputtering system, and relates to the technical field of mask plates. The problem that in the prior art, the sputtering film forming shadowis large due to the fact that the gap between mask strips and a substrate is large, and as a result, the product yield is low can be solved. The mask device comprises a mask plate and a plurality ofmask strips; and the surface of the side, close to the mask plate, of at least one mask strip is provided with a plurality of strip-shaped metal structures, the multiple metal structures are arrangedin the length direction of the mask strips at intervals, and the thermal expansion coefficient of the metal structures is larger than that of the mask strips. The mask device and the sputtering systemare used for sputtering film forming.

Description

technical field [0001] The invention relates to the technical field of mask plates, in particular to a mask device and a sputtering system. Background technique [0002] With the rapid development of display technology, users' requirements for large-size display and image quality are gradually increasing. Large-size OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display devices are more and more popular among users due to their many advantages. of favor. Existing OLED devices usually consist of an anode layer, a light emitting layer and a cathode layer. According to the light output direction, it can be divided into two types: bottom-emitting devices and top-emitting devices. Because the top-emitting device can obtain a larger aperture ratio and can significantly improve the brightness of the screen, it has become a hot research topic in recent years. OLED top-emitting devices require a transparent cathode to increase light transmittance, and the transp...
