Preparation method of micrometer LED linear light-emitting body

Abstract

The invention discloses a preparation method of a micrometer LED linear light-emitting body. The preparation method comprises the steps of firstly, fabricating a linear body from a matrix, and spraying a gas formed by a preset compound element and organic radical onto the heating linear body crystal by organic metal vapor deposition so that the linear body generates chemical reaction and the required multi-layer thin film is formed; secondly, performing metal evaporation, exposure / developing, photoresist coating, etching, half-cutting / energization point test, full-cutting (cutting) and crystalexpansion / appearance detection; and finally, packaging and putting into a warehouse. Linear body crystal lines drops and are positioned at an upper end of a vertical cylindrical reaction cavity in adrop way, the required multi-layer thin film is plated on a surface of the linear body crystallization basic line by a gas inlet in an upper end in a spraying manner, the effect that the linear light-emitting body can circumferentially emit light is further achieved, and the crystal grain volume of the obtained extreme slim linear body also can be effectively cut and assembled and is used as the characteristic.

Description

technical field [0001] The invention relates to a preparation method of a micron LED linear illuminant, in particular to a micron LED, which uses the linear body as the crystallization baseline, and makes related materials adhere to form the LED epitaxial line body after heating, and utilizes the upright columnar reaction A method for preparing a cavity for spray coating. Background technique [0002] The basic principle of LED is: light-emitting diode is a special kind of diode, which is also composed of semiconductors. These semiconductor materials will be prepared in advance through implantation or doping processes to form P and N structures. Like other diodes, the current in light-emitting diodes can be Easily flow from the P pole (anode) to the N pole (negative pole), but not in the opposite direction; then use the combination of semiconductor holes (P type) and electrons (N type) to release photons; make two different charge carriers The holes and electrons flow from ...
