ABSTRACT:
Method and apparatus for improved maskless deposition of electronic and biological materials using an extended nozzle. The process is capable of direct deposition of features with linewidths varying from a few microns to a fraction of a millimeter, and can be used to deposit features on targets with damage thresholds near 100° C. or less. Deposition and subsequent processing may be performed under ambient conditions and produce linewidths as low as 1 micron, with sub-micron edge definition. The extended nozzle reduces particle overspray and has a large working distance; that is, the orifice to target distance may be several millimeters or more, enabling direct write onto non-planar surfaces. The nozzle allows for deposition of features with linewidths that are approximately as small as one-twentieth the size of the nozzle orifice diameter, and is preferably interchangeable, enabling rapid variance of deposited linewidth.
