摘要
An effect of an applied field on processing accuracy of microfabrication by using anodic oxidization of aluminum has been investigated. Aluminum sheets have been anodized in oxalic acid applying a dc magnetic field of 7.0 kOe. Applying field during the anodization process reduces the width of the anodization by 33% compared to that without the magnetic field. It was found that the applied field affects the growth direction of the anodic oxidization along the field direction due to Lorentz force. This indicates that the microfabrication technique by anodic oxidization of aluminum in an applied field is useful method for realizing micro electro mechanical systems (MEMS) devices, such as microactuators.
