Abstract: Provided are a structure and fabricating method of a new inverter for controlling a threshold voltage of each location when an inverter circuit is manufactured using an organic semiconductor on a plastic substrate. In general, p-type organic semiconductor is stable. Accordingly, when the inverter is formed of only the p-type semiconductor, a D-inverter composed of a depletion load and an enhancement driver has large gains, wide swing width and low power consumption, which is more preferable than an E-inverter composed of an enhancement load and an enhancement driver. However, it is impossible to form a depletion transistor and an enhancement transistor on the same substrate while controlling them by locations.

Abstract: A surface treatment method of an FRP substrate is provided. According to the method, an FRP substrate that is less deformed than a conventional flexible substrate material is used, and surface roughness, which is a drawback of the FRP substrate, is improved so that it may be applied to the fabrication of a device.
