Rezumat | ||||||
Shape evolution during through-mask electrochemical micromachining was investigated to study the problem of dissolution (electrodeposition) uniformity at low and high aspect ratio. Mathematical model to predict shape evolution by assuming primary current distribution is advanced. The results of calculation are compared with the experimental data on anodic dissolution of copper in neutral nitrate solutions. |
