研究目的
To develop a simple, cheap, and quick method for obtaining shadow masks by electrochemical corrosion of stainless steel for use in electro-optic devices.
研究成果
A simple, cost-effective method for fabricating shadow masks through electrochemical corrosion of stainless steel was successfully developed and applied in the production of OLED devices, demonstrating its potential for use in electro-optic device manufacturing.
研究不足
The method's precision is limited by the photolithography and electrochemical corrosion processes, which may not achieve the same level of detail as more sophisticated techniques.
1：Experimental Design and Method Selection:
The method involves electrochemical corrosion of stainless steel to create shadow masks.
2：Sample Selection and Data Sources:
Stainless steel type 302 sheets were used.
3：List of Experimental Equipment and Materials:
Includes a Keithley Source Meter 2410C, HCl solution, and polyimide HD-
4：Experimental Procedures and Operational Workflow:
41 The process involves cleaning the steel, photolithography to transfer the pattern, electrochemical corrosion, and finally, the removal of the polyimide layer.
5：Data Analysis Methods:
The performance of the shadow mask was evaluated by fabricating an OLED device and measuring its turn-on voltage and luminance.
