Abstract: The present disclosure proposes a micro LED and a method of forming the same. After a body of layers to structure a PN junction is formed sequentially on the outer wall of a buffer layer column, a first electrode is formed on the outer side of the body of layers that structured the PN junction. A second electrode is formed on the inner side of the body of layers that structured the PN junction after the buffer layer column is removed. The first electrode and second electrode are insulating to each other in areas outside of the body of layers structuring the PN junction. The micro LED formed is of a tube structure. The tube-structured micro LED can effectively lower the impedance imposed by the body of layers structuring the PN junction between the first and second electrodes, and thus enhance conductivity and illumination efficiency of the micro LED.

Abstract: A control method for differentiated etching depth is provided. The method includes: providing a first etching stop pattern layer in a panel having stacked structure; adopting a first etchant to perform a first etching process to the panel such that a location of the panel provided with the first etching stop pattern layer forms a first etching depth, and forms a second etching depth at a location of the panel without providing the first etching stop pattern layer; through controlling an etching time, the second etching depth is deeper than a bottom of the first etching stop pattern layer; and adopting a second etchant to perform a second etching process to the panel in order to etch and remove the first etching stop pattern layer. In a same mask process, through changing the etchant, different depths are etched and formed to reduce the time consuming and decrease the production cost.

Abstract: A method for manufacturing an organic thin film transistor includes steps of: forming a graphene layer on a surface of a metal substrate; covering a surface of the graphene layer with an organic solution and heating the graphene layer to form organic semiconductor nano lines on the surface of the graphene layer; and transferring the organic semiconductor nano lines to a target substrate. The graphene layer is formed on the surface of the metal substrate in mass production. The organic semiconductor nano lines (monocrystalline semiconductor) are grown in mass production by the graphene layer. The semiconductor layer having organic thin film transistors is formed after transferring the organic semiconductor nano lines on the target substrate. A large amount of the organic semiconductor nano lines can be formed simultaneously on the surface of the metal substrate with a large area.
