Abstract

This paper focuses on the fabrication of polymer thin film resistors by the digitalization of microfluids. A fabrication system with drop-on-demand(DOD) jetting for polymer thin film resistors was setup based on the digitalization of microfluids. The poly(3.4-ethylenedioxythiophene)/poly(styrenesulfonate)(PEDOT/PSS) was jetted on the Resin Coating(RC) paper substrate at the best overlap of 13.4%

the film consisting of polymer droplets was quickly dried by the capillary action of the paper to form a thin film resistor and the resistance value was reduced by annealing processing. The influences of the system parameters on the diameter of the droplets were researched. The thin film resistors with the resistances varied from 3.5 to 23.2 MΩ were obtained by changing the row number

column number

layer number and the annealing conditions. The results show that the resistance is almost proportional to the row number and decreases with the number of the rows and layers increases. Furthermore

the resistance of the printed thin film resistors has decreased by 10%—40% due to the annealing processing. With the same fabrication parameter and annealing condition

the thin film resistors show good uniformity. The resistance of the resistors decreases when the temperature increases and reaches a stable level. The experimental results indicate that the fabrication of the polymer thin film resistors based on the drop-on-demand technology has advantages on the simple process

low costs and good electrical properties.
