  • Employing capillary forces at the solvent/water interface for microstructure assembly.
  • Evaporation of solvents to finalize deposition.

    • Main Results:

    • Successfully deposited approximately 40,000 SiO(2) plates (10x50x0.3 micrometers) on a 20 cm(2) substrate with a 0.52 deposition probability.
    • Demonstrated that deposition probability is dependent on solvent type and influenced by the free energy change at the interface.
    • Confirmed that capillary forces govern the deposition probability.

    Conclusions:

    • The developed blade-coating technique provides a viable method for fluidic self-assembly of microstructures.
    • The process is controllable and scalable for applications in microfabrication.
    • This technique holds promise for the deposition of micrometer-sized electronic devices on large substrates.
