The demand for fabricating microstructures with three-dimensional (3D) geometry has increased in many fields due to potential applications the geometry gives. We previously developed the Reaction-Diffusion-Mediated Photolithography (RDP) to produce microstructures with unique pseudo-3D feature though the method was proven only with limited set of conditions and dimensions. In this work, we further investigate the effect of various parameters on growth behavior of pseudo-3D microstructures. The structural dimension of the microstructure is expanded to wide range of dimension by concomitantly adjusting parameters to balance the reaction and diffusion process. The operation condition along the separation between reaction sites is optimized, producing microstructures with broad range of spacing. Moreover, we study how growth behavior of microstructure alters in the presence of lens effect. This RDP technique produces pseudo-3D microstructures from many photocurable resin in highly-controlled manners without complex instrumentation. We believe that the technique will serve as a unique method to design and fabricate micropattern or microparticles with pseudo-3D feature. |
