Anode structure and anode structure manufacturing method

Abstract

The invention relates to an anode structure and an anode structure manufacturing method and belongs to the semiconductor technological field. The anode structure is composed of a substrate, a drivingcircuit, a passivation layer, first anode layers, second anode layers and third anode layers; the driving circuit is fabricated on the substrate; the passivation layer is fabricated on one side of thedriving circuit, wherein the one side of the driving circuit is far away from the substrate; the first anode layer is fabricated on one side of the passivation layer, wherein the one side of the passivation layer is far away from the driving circuit; the second anode layer is fabricated on one side of the first anode layer, wherein the one side of the first anode layer is far away from the passivation layer; the third anode layer is fabricated on one side of the second anode layer, wherein the one side of the second anode layer is far away from the first anode layer; through holes corresponding to the first anode layers are formed in the passivation layer; the through hole pass through the passivation layer and are filled with a conductive material so as to electrically connect the driving circuit with the first anode layers; and the second anode layer is a Al:Ag structural layer. With the above structure adopted, the problems of complicated manufacturing process and high possibilityof being damaged of anode layers which are caused by the setting of anode spacer columns in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an anode structure and a method for manufacturing the anode structure. Background technique [0002] With the continuous expansion of the application fields of semiconductor devices, in order to ensure the performance of semiconductor devices, the manufacture of semiconductor devices has received extensive attention. Among them, the reflective performance of the anode structure in the OLED device directly determines the display performance of the OLED device, and aluminum is generally used as the anode material. Due to the characteristics of aluminum, its thickness has little effect on the reflective performance. To improve the reflective performance of the anode structure, it is necessary to set a thicker aluminum metal anode, and if the thickness of the aluminum metal anode is larger, it will cause the cathode of the OLED device It is easy to have the problem of disconn...
