Description
Technical field
The present invention relates to a kind of 3 D stereo deposition mask plate, belong to OLED and make the field.
Background technology
OLED, namely Organic Light Emitting Diode claims organic electric laser to show again.The OLED technique of display is different with traditional LED display mode, need not backlight, adopts extremely thin coating of organic material and glass-base, and when electric current passed through, these organic materialss will be luminous.And the OLED display screen can do lighter and thinnerly, and visible angle is bigger, and can significantly save electric energy.The premium properties of OLED makes its accessory-mask plate obtain unprecedented development space.Usually, when making active display, mask is used to deposit the layer with predetermined pattern, namely when the layer of deposition such as organic layer, utilizes the mask in the hole with special pattern, form in substrate figure with corresponding and hole layer.At present commonplace is the planar metal mask plate, but along with the making rapid progress of science and technology, the functional requirement of electronic devices and components is becomed privileged direction and developed also towards diversification, and corresponding transfer can not be satisfied this requirement with plane deposition mask plate.
In the metal mask board manufacturing process in the past and since when exposure mask precision and etched precision very big to the metal mask amount pattern precision influence as end article, so in each operation the dimensional precision of managing graphic accurately.In the manufacturing in the past, because the metal at the big chromium of linear expansivity, stainless steel etc. forms metal mask plate, so result from the dimensional precision difference that small temperature difference on the metallic substance makes each metal mask that makes, have the problem of the metal mask that is difficult to obtain the same size precision.From material, the general metal mask plate that forms at the big metal of linear expansivity results from the dimensional precision difference that small temperature difference on the metallic substance makes each metal mask that makes, and has the problem of the metal mask that is difficult to obtain the same size precision.Rhometal has been then because added ferro element, thereby improved hardness and the magnetic of mask plate, and in this scope, iron level is more high, and the thermal expansivity of mask plate is more low, and when being applied to the evaporation process process, the evaporation position progress of organic materials is more high.Invar alloy contains the nickel of 32%-36% usually, and Invar alloy also is invar, and its average coefficient of expansion is generally 1.5 * 10-6 ℃.Nickeliferously reached 1.8 * 10-8 ℃ at 36% o'clock, and all do not change during ℃ to 100 ℃ in room temperature-80.Nickel content increase and decrease within the specific limits can cause the rapid variation of iron, the nickeline wire coefficient of expansion.Therefore for the very high evaporation mask plate of accuracy requirement, Invar alloy is first-selected material.Other materials all can be because of being heated and the expansion effects precision in evaporate process, thereby influenced quality product greatly.
But Invar alloy all is to adopt the method for melting to obtain simultaneously, and power consumption is high, the technical requirements height, thereby price also is quite high.Seriously limited the development prospect of Invar alloy.
Therefore, the plane deposition mask plate of prior art reaches the material that is used for the deposition mask plate, has seriously hindered the development of active display.The active display of producing with the plane deposition mask plate of prior art does not satisfy market to its high request.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of 3 D stereo deposition mask plate of high Fe content, have sunk area and elevated regions, and comprise two kinds of elements of iron and nickel, this mask plate precision height, homogeneity height, plate face quality and opening quality are good, thermal linear expansion coefficient is minimum, satisfies the evaporation requirement well.
