| dc.description.abstract | In this era of rapid technological development, electrochemical deposition technology has a certain position in the fields of optoelectronics, energy conversion, sensing technology, etc., in addition to the booming semiconductor and electronic industries in recent years, and is an important Technology. The local electrochemical deposition studied in this experiment can be applied to more precise areas.
This experiment continues the ＂different-axis double helix calculus＂ of scholar Wang[13], the ＂controllable cylinder diameter double helix＂ of scholar Lin[14] and the ＂Pulse Width Modulation PWM Cylinder Diameter Control Method＂ of scholar Yang[15]. Observing the formation of copper pillars in real-time images, and guiding the width of the pillar diameters, continuing previous research and discovering more controllable environmental variables. In this experiment, different cathode and anode distances are used to achieve different pillar diameters. And we provide the recommended interval of critical distance under different voltage conditions. In addition to the improvement of the algorithm, this experiment made a smaller anode, and also used this anode to make a double helix microstructure and control its diameter. Various methods were studied to make the electroplated product more beautiful and to increase the success rate of the experiment. The influence of the variable on the experiment has created a more complete data and conducted in-depth discussions and research. | en_US |
