Abstract

The invention discloses a method for constructing an organic micron linear array with a form board assisting in volatilization induced self-assemble. The method comprises the following steps that (1) a substrate is washed through cleaning fluid in an ultrasonic mode, then the substrate is immersed in the piranha solution and processed by an oxygen plasma, and the surface of the substrate is made to have strong wettability; (2) the form board is constructed on the substrate; (3) the micron linear array is grown on the form board, the pre-processed form board is inserted in the organic solution for growth, and through volatilization induced self-assemble, the large-area highly-aligned organic micron linear array is obtained. The method is of great significance to manufacturing of large-area high-performance photoelectron micro-nano devices based on organic optoelectronic materials and further achieving of micro-nano device integration.

Description

technical field [0001] The invention belongs to the field of semiconductor devices, and in particular relates to the preparation of top-down periodic wetting / anti-wetting templates, bottom-up solvent volatilization self-assembly, anti-wetting and fingering convection. Background technique [0002] Currently, the top-down processes commonly used in the industrial production of semiconductor devices require huge production lines and large processing equipment under ultra-clean conditions. This results in wasted material and increases the production and development costs of the device. A preparation method that achieves the lowest consumption of materials and the lowest use of energy is undoubtedly crucial to the sustainable development of the entire society. Many research groups have tried to use the template-assisted physical vapor transfer method to prepare small molecule organic micro-nano single crystal structures. However, this method requires materials with high therma...
