Microdrop Inkjet Micropatterning System

Compared to other patterning techniques, inkjet printing provides a very versatile and low cost microfabrication capability that has attracted significant research and industrial interest. Inkjet technology can be used to pattern a variety of liquids including polymers, proteins, and various solvents. This technique is used for non-contact patterning onto rigid, flexible, rough, smooth, and 3-D substrates. This process is accurate, high resolution, high speed, and consumes very little material as compared to a lithographic process.

This Microdrop System has the following spcifications:

    20 cm x 20 cm horizontal travel
    8 cm vertical travel
    5 um horizontal and 10 um vertical placement accuracy
    1 um horizontal and 5 um vertical repetition accuracy
    0.5 m/s^2 maximum acceleration
    100mm/s maximum speed

Materials and Solvents

Materials (solvents) printed using this system must have a boiling point in excess of 100°C in order to avoid cavitation bubbles which prevent stable dispensing. The fluid makes direct contact with the following materials: glass, PTFE and PEEK. It is possible to use the solvents listed below, but never HF (it will destroy the glass) and not high concentrated base like NaOH (after a while it will change the surface of the glass).

    acetophenone,
    anisole,
    benzylalcohol,
    butylacetate,
    cyclohexanol
    diethylene glycol,
    1,4-dioxane,
    DMA,
    DMF,
    DMSO,
    n-dodecane
    ethylbenzene,
    ethylene glycol,
    hexylbenzene,
    hexyliodide,
    methyl-benzoate,
    N-methyl-pyrrolidone,
    1-octanol
    1,3-propanediol
    propylene carbonate
