Ink-Jet Printed Passive Electronic Components: Metal-Insulator-Metal Device
Abstract:In this study, an ink-jet printed poly(methylmethacrylate)(PMMA) solution with mixed organic solvent to form insulator was presented. A detail observation of ring edge behavior for Ink-Jet Printing (IJP) device and its process parameters relation had been evaluated. One of the layer structure consisted of a thin layer of adhesive polymer (polyvinyl acetate: PVA) between bottom electrode and printed insulator layer, and then to treat the spincoated thin PVA with CF4-plasma to raise the contact angle up to 40∼50 degrees. Besides, a mixed solvent comprised of one solvent having lower boiling point and another one having higher boiling point was used to improve the ring-effect as well. Heating the platform as the droplet is landing also mitigates the effect of coffee-ring. Single-layer insulator device is very easy to be leakage, so triple-layered insulator device is made and then has better capacitance characteristic. Experimental results indicated that the leakage current for ink-jet fabricated multi-layered insulator was about 10nA/cm2 at 3V, and the dielectric constant for the printed insulator was about 3.0.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
