Problems solved by technology

This method has great limitations and can only be used for some liquids whose properties are within a given extremely limited range. For polymer solutions with high molecular weight and long molecular chains showing high viscoelastic liquid properties, it must be used The method of dilution can be printed out, and after dilution, more droplets are needed to print the same amount of material, and it becomes more difficult to achieve effective printing

Embodiment 1

[0033] Embodiment 1 inkjet printing system

[0034] In order to solve the problems existing in the prior art, the present invention proposes a novel printing system of multi-aperture synthesis. In order to facilitate the understanding of the present invention, the existing inkjet printing system is briefly described here.

[0035] Figure 1a Shown is a schematic diagram of an existing inkjet printing system, Figure 1a The system includes:

[0036] sample stage;

[0037] A printhead that includes ink reservoirs and orifice sheets, such as Figure 1b shown. The orifice sheet is provided with orifices of the same diameter, and each orifice can be driven independently for printing operation.

[0038] A printing driving device, used to drive the nozzle holes of the printing head to perform printing operation, the printing driving device may be, for example, a waveform generator;

[0039] The positioning driving device is used to drive the printing head or the sample stage to ...

Embodiment 2

[0056] Embodiment 2 carries out the method for inkjet printing

[0057] Traditional semiconductors are manufactured on silicon wafers, so they are also called silicon-based manufacturing. Semiconductor manufacturing technology is divided into front-end and back-end process parts. The front-end process flow includes deposition, removal, circuit routing and electrical property adjustment; the back-end process flow includes heat treatment and packaging technology. Most current fabrication of organic transistors is based on the fabrication process of silicon-based semiconductors. The specific process is: design the drain and source of the semiconductor device and circuit wiring, and make it into a mold. Coating photoresist on the surface of the base body, using photoetching technology in conjunction with the use of the mold, forming on the photoresist film. Then, it is placed in an evaporator, and the conductive metal is melted at high temperature to form a gaseous metal, which...

Abstract

The invention provides a printing system, a printing method and a method for printing a thin film transistor and an RLC circuit; wherein, the system comprises a sample station, one or more printing heads, printing driving device driving the sprouting hole of the printing head to perform the printing operation and a positioning driving device driving the printing head or sample station to perform the printing and positioning; a sprouting hole plate is arranged on each printing head and the sprouting holes of different apertures are arranged on one or more printing heads. The sprouting hole with suitable aperture can be selected for the system according to the liquid of different natures, so as to realize the reliable printing.

Description

technical field [0001] The invention relates to inkjet printing technology, in particular to a printing system, a printing method and a method for printing thin film transistors and RLC circuits. Background technique [0002] Since the printing technology was first applied for patent protection for commercial use in 1867, after a hundred years, the world's truly commercial inkjet printer was born. Inkjet printing technology has been widely used in today's industrial production and daily life: packaging printing manufacturing technology is a typical example of industrial application; and home and company terminal inkjet printers are more familiar to the public. Conductive polymers were first discovered in the 1970s, and the Nobel Prize in Chemistry in 2000 was awarded to three inventors of conductive polymers: American physicist A.J.Heeger, American chemist McDiarmid (A.G.MacDiarmid) and Japanese chemist Shirakawa Hideki (H.Shirakawa). This has accelerated the application o...
