Fabricating Devices Using Nano-Particulates with Direct Write Technology


Article Preview

Nano-particulates are being used in conjunction with Direct Write Technologies for fabrication of electronic devices, sensors, and in tissue engineering. The materials being used in Direct Write Technologies predominately are suspensions, solutions or pastes comprised from nano-particulate metals, oxides or organics. This paper will present a comparison of several nano-particle silver inks being evaluated for use by one of these Direct Write Technologies, Maskless Meso-Scale Material Deposition (M3D) being developed by Optomec, Inc., Albuquerque, NM. USA. The silver inks in this case were deposited by the M3D process and then cured by sintering by both oven and by laser. Optical microscopy and Scanning Electron Microscopy (SEM) were used to examine the resultant cured material. The surface resistivity of these deposits was determined as a measure of their quality. A soft magnetic inductor material was also fabricated through a combination of nickel and iron oxide nano-particles. The results obtain with this inductor material are also discussed.
