Problems solved by technology

The generated sulfides or oxides will absorb blue light, which will reduce the reflectivity of the blue light band in the reflective layer, thereby reducing the reflectivity of the film. In addition, it is easy to produce silver grain growth or silver atom aggregation.
Therefore, the silver-based thin film will have problems such as decreased conductivity and reflectivity, and poor adhesion to the substrate.

preparation example Construction

[0027] In the specific implementation process, the present invention is used for the preparation method of vacuum magnetron sputtering silver-based alloy target blank, including the following process steps:

[0028] (1) Use 10 according to the ratio -5 The precision balance accurately weighs the weight of the metal elements required for each alloy, and uses a high-frequency induction furnace with an argon protection device for alloy melting; first, put the metal copper into a graphite crucible and heat it up to melt, and then heat it up at 1120 ° C ± 50 Add zinc at about ℃ for alloying smelting. After smelting, lower the graphite crucible to the cooling platform, and cast it under the conditions of hot top protection, permanent magnetic stirring and directional forced cooling. The obtained copper-zinc alloy billet is cooled to room temperature. Afterwards, it is taken out for rolling and shearing to obtain a copper-zinc binary master alloy for future use. Before smelting, high...

[0034] After the smelting is completed, the specific chemical composition of the silver-based alloy target blank in this embodiment is as follows: the copper content is 0.5wt%; the yttrium content is 0wt% to 1.0wt%; the additional alloying elements are selected from the following elements One or more than two kinds of: Ni, Ce, Zn, Al, Mg, Nd, Si, the total addition amount is 0.035wt%-0.14wt%; the balance is silver.

[0035]

[0036] Note: Alloy content is mass percentage (wt%)

[0037] After grinding, polishing, and corrosion, the performance of the alloy blank is detected and tested. The microstructure of the silver-based alloy target blank in this example is shown in the attached figure 1, as the addition of element Y increases, the grain size of the sample becomes smaller; the grain size of the 4# sample with the addition of element Y 1.0wt% is obviously refined, but black lumps are precipitated. The surface color of each silver-based alloy target blank changes with tim...

Description

technical field [0001] The invention belongs to the technical field of metal material processing, and in particular relates to a silver-based alloy target blank for vacuum magnetron sputtering and its preparation method and application. Background technique [0002] Silver-based films made of silver or silver-based alloys have some excellent properties, such as: high reflectivity, high transmittance, low extinction coefficient, high thermal conductivity, low resistivity, and excellent surface smoothing effect. Therefore, silver-based alloys are widely used in the preparation of reflective films for optical recording media, semi-transmissive reflective films, thermal diffusion films, reflective electrode films for flat panel displays, and electromagnetic wave shielding films. For example, the organic electroluminescence (organic EL) display is a self-luminous flat panel display, so it needs a reflective anode film composed of reflective metal films such as silver, aluminum, c...
