摘要:
Disclosed herein are compositions useful in forming organic active patterns that may, in turn, be incorporated in organic memory devices. The compositions comprise N-containing conjugated electroconductive polymer(s), photoacid generator(s) and organic solvent(s) capable of dissolving suitable quantifies of both the electroconductive polymer and the photoacid generator. Also disclosed are methods for patterning organic active layers formed using one or more of the compositions to produce organic active patterns, portions of which may be arranged between opposed electrodes to provide organic memory cells. The methods include directly exposing and developing the organic active layer to obtain fine patterns without the use of a separate masking pattern, for example, a photoresist pattern, thereby tending to simplify the fabrication process and reduce the associated costs.

摘要:
A method of driving a multi-state organic memory device which includes an organic memory layer between upper and lower electrodes. The method comprises continuously applying voltages having different polarities to conduct switching into a low resistance state, and applying a single pulse to conduct switching into a high resistance state. A multi-state memory is realized using one memory device, since it is possible to gain three or more resistance states, thus significantly improving integration. The method has excellent reproducibility, and the resistance state induced by multiple pulses has an excellent nonvolatile characteristic.

A method of manufacturing a nonvolatile organic memory device including a memory layer interposed between an upper electrode layer and a lower electrode layer, which includes dispersing ions of conductive nanoparticles in an organic material disposed between the two electrode layers and then reducing the ions of conductive nanoparticles into conductive nanoparticles in the organic material to form a desired memory layer. In addition, a nonvolatile organic memory device manufactured by the method of the current invention is also provided. The method allows the memory device to be manufactured using a rapid, simple, and environmentally friendly process, without the need for an encapsulation process. As well, the memory device has a low operating voltage, and hence, is suitable for application to various portable electronic devices that must have low power consumption.

The present invention relates to a method for fabricating a hollow microneedle having a variable appearance. The method makes it possible to vary the length of the microneedle, the outer and inner diameters of the upper and lower parts thereof, the aspect ratio, the sharpness, and the structural bending rate thereof, in accordance with the purposes of the same. Accordingly, the appearance of the hollow microneedles according to the present invention can be varied with flexibility according to various purposes, such as the transferring of medication and the taking of a blood sample, and to various factors, such as the target part for the medication transfer, the depth of the medication transfer, and the amount and viscosity of the medication. Thus, the microneedle can be used as a multi-purpose device for transferring medication.
