| Outline of Final Research Achievements |
Electrospray deposition (ESD) through a stencil mask has attracted attention, because it is a high-speed patterning of bio/organic polymer materials over large areas and with high resolution and based on completely-dried nanoparticles of them. However, it is difficult to generate nanopatterns due to the clogging of holes in the stencil mask. This paper proposes novel ESD methods to form patterns smaller than the stencil mask holes by utilizing a MEMS-fabricated microstencil mask to control the electrostatic field.
Two different approaches are proposed in this paper: (1) to control the gap between the stencil mask and the substrate by using magnetic force; and (2) to control the electric field line by changing applied voltages. We conceived novel MEMS fabrication processes and successfully fabricated both of microstencil masks. The patterning results with the proposed microstencil mask showed that the feasibility of two proposed methods to generate smaller patterns than the mask holes.
