Problems solved by technology

[0004] The purpose of the present invention is to overcome the point source evaporation equipment in the prior art. When the material is exhausted and the source needs to be replaced, the material temperature rises for a long time, the material evaporation rate stabilizes for a long time, the cost of using a crystal oscillator is high, and material leakage is prone to occur. The problem of monitoring the evaporation rate of materials by interfering with the crystal oscillator device

Abstract

The invention relates to the technical field of semiconductor technology, in particular to an evaporating cavity lining device, an evaporating system thereof and an evaporating device. The evaporating cavity lining device comprises a cavity assembly, wherein the cavity assembly comprises a first shell and a second shell; the first shell is provided with a first opening end and a second opening end arranged oppositely; the first opening end is externally connected with the evaporating device; a steam passage allowing steam to circulate is formed in the first shell; the second shell communicates with the second opening end; and a material storing area for storing the steam from the steam passage is formed in the second shell. The evaporating cavity lining device can ensure that the evaporating device warms organic material in advance, and the situation that the evaporated material enters an evaporating area to interfere with a base plate is avoided.

Description

technical field [0001] The invention relates to the technical field of semiconductor technology, in particular to an evaporation chamber lining device, an evaporation system, and an evaporation device. Background technique [0002] Organic Light-Emitting Diode (OLED), also known as organic electric laser display, organic light-emitting semiconductor, is a device that uses a multilayer organic thin film structure to generate electroluminescence. OLED has a wide viewing angle, high contrast, and low power consumption. The advantages of electricity, fast response, and wide operating temperature range have attracted widespread attention in the display field. [0003] OLED luminescence needs to evaporate several layers of organic materials between the substrate and the packaging mechanism. The evaporation devices are divided into point source evaporation equipment and line source evaporation equipment. Add organic materials, vacuumize to a high vacuum environment, heat the cruci...
