Technical field
The present invention relates to the metallic film technology of preparing, specifically a kind of spray ink Printing prepares the method for metallic film.
Background technology
Metallic film is widely used, and especially the metallic film that has certain figure and a physical and chemical performance at microelectronic has constituted the basis of nearly all microelectronic device.Metallic film not only is used to connect lead, contact, and can be used for finishing multiple functions such as sensing, catalysis, electromagnetic shielding.Conventional now metallic film preparation technology generally needs technologies such as plated film and etching, the preparation process complexity, and cost is higher.
Inkjet technology is one of major technique that generally adopts in the modern handle official bussiness printing, is divided into continous way and random mode two classes according to ink-jetting style.The continous inkjet technology utilizes Piexoelectric actuator that the shower nozzle ink inside is applied fixation pressure, makes its continuous injection, utilizes the heading of deflection electrode change ink droplet and forms pattern.The only ink-jet when needed of random mode ink-jet technology, it mainly contains two kinds of bubble type and piezoelectric types.Bubble type is provided with well heater on the tube wall of shower nozzle, under the electricimpulse effect, form very little bubble on the well heater, and the bubble expanded by heating produces pressure-driven ink droplet jetting nozzle.Piezoelectric type utilizes the minute-pressure electric device to make transverter, produces pressure wave and drive the ink droplet jetting nozzle under the pulsed voltage effect.The a plurality of ink-jet systems of configuration in the general printer, each ink-jet system connects with the print cartridge that the different colours ink is housed, and can print colourful pattern.In recent years, the researchist begins to attempt it is used for the preparation of plane function material, and obtain some preliminary results, as prepare conducting polymer film (D.Pede, G.erra, andDe Rossi, Mater.Sci.Eng.C.5 (1998) 289), preparation color organic light emitting diode (Adv.Mater.11 (1999) 734 for S.-C.Chang, et al), prepare function nano structure graph (H.Y.Fan by the self organizing function ink that has that contains tensio-active agent, et al, Nature, 405 (2000) 56).Inkjet technology is as the functional materials preparation means of plane function material particularly because it has and is easy to prepare complex figure, but and the characteristics of pointwise control composition, be expected under a stable condition, to be used to replace plated film, the photoetching process of existing complexity.But utilize inkjet technology to prepare metallic film and yet there are no report.
Summary of the invention
The purpose of this invention is to provide the method that a kind of technology is simple, cost is low spray ink Printing prepares metallic film.
