Sintering nano-particles on low temperature materials

Abstract

Direct Writing (or Printing) technologies use nano-particle inks and pastes to build mesoscale-scale devices. The term mesoscale refers to sizes from approximately 10 microns to 1000 microns, and covers the range between geometries deposited with the more conventional thin film and thick film processes. These processes begin with dispensing of liquid molecular precursors or colloidal suspensions of metal, dielectric, ferrite, or resistor nano-powders. The dispensing is accomplished by either controlling an aerosol stream or bead of thick viscous paste to produce features with dimensions as small as 10 microns. In a typical configuration, the substrate is placed on a platen that is attached to a high precision CAD/CAM stages, so that intricate geometries may be produced. Either laser, photonic or furnace thermal treatments is used to process the deposit to the desired state. Application of these technologies to the production of direct write inductors, capacitors, and resistors is presented, along with electrical characterization of these components.Direct Writing (or Printing) technologies use nano-particle inks and pastes to build mesoscale-scale devices.
