Printing high resolution electrodes is an important technology for realizing the high integration of sensing devices and organic radio-frequency tags as well as for further improving the performance of organic transistors. Reverse offset printing method can form fine patterns of functional materials such as silver nanoparticles with a submicrometer line spacing at room temperature. As a method for forming the electrodes of organic transistors, it is possible to shorten the channel length by using the reverse offset printing method capable of high resolution printing. It enables high integration and high-speed operation of transistors. However, it is known that, as the channel length is shortened, the contact resistance at the electrode/semiconductor interface greatly affects the total resistance of devices and the mobility decreases. Transfer line method (TLM) is widely used as a method to estimate the magnitude of the contact resistance. However, resistance values can not be estimated accurately when the variation in transistor characteristics is large. In this research, the contact resistance and channel resistance were analyzed using four-terminal measurement which is one of the methods of estimating the contact resistance. It was found that the crystallinity of the channel material remarkably varies, depending on the conditions for adding the polymer material to semiconductor. In addition, correlation between the carrier injection property and the energy level of the electrodes was observed. The application of four-terminal measurement to printed devices in this research can be expected to be a major guideline for improving the performance of organic transistors. |
