Embodiment 1

[0035] Example 1: See Figure 1-6, a preparation device for gallium nitride thin films, comprising a preparation chamber 1 and an evaporation chamber 2, the evaporation chamber 2 is fixedly connected to the bottom end of the preparation chamber 1, the interior of the evaporation chamber 2 is fixedly connected to a quartz crucible 3, and the quartz crucible 3 The inside is fixedly connected with a heating wire 4, the top of the evaporation chamber 2 is fixedly connected with an ionization chamber 5, the outer wall of the preparation chamber 1 is provided with a thermal insulation structure 6, and the two sides of the preparation chamber 1 are provided with an explosion-proof structure 7 near the top. One side inside the preparation chamber 1 is fixedly connected with a radio frequency ionization gun 8, and the middle position of the top of the preparation chamber 1 is fixedly connected with a vacuum pump 12. The model of the vacuum pump 12 can be 2BV-5110, and one side of the pr...

Embodiment 2

[0040] Embodiment 2: The thermal insulation structure 6 is composed of a cavity 601, a casing 602, a connecting rod 603, a nut 604, a through hole 605 and a thermal insulation rock wool 606. The casing 602 is arranged outside the preparation bin 1, between the casing 602 and the preparation bin 1 A cavity 601 is provided, and a plurality of sets of through holes 605 are arranged inside the shell 602. A plurality of sets of connecting rods 603 are fixedly connected to the outer wall of the preparation bin 1, one side of the connecting rods 603 runs through the through holes 605, and the outside of the connecting rods 603 One side is provided with a nut 604, and the interior of the cavity 601 is filled with thermal insulation rock wool 606;

[0041] The outside of one side of the connecting rod 603 is provided with threads, and there is a one-to-one correspondence between the connecting rod 603 and the through hole 605;

[0042] Specifically, such as figure 1 and Figure 4 As ...

Embodiment 3

[0043] Embodiment 3: Explosion-proof structure 7 is made up of through pipe 701, piston 702, fixed rod 703, tension plate 704 and spring 705, and through pipe 701 is respectively arranged in the inside of preparation bin 1 both sides, and inside through pipe 701 is provided with piston 702, one side of the piston 702 is fixedly connected with a fixed rod 703, one side of the fixed rod 703 is fixedly connected with a tension plate 704, and a spring 705 is fixedly connected between the two ends of one side of the tension plate 704 and the preparation bin 1;

[0044] Specifically, such as figure 1 and image 3 As shown, when in use, if the pressure inside the preparation chamber 1 is too high, the piston 702 will be pushed out under the relatively high pressure, and at this time, the fixed rod 703 will push the tension plate 704 outward to make the tension The tight plate 704 drives the spring 705 to stretch until the piston 702 is ejected from the inside of the through pipe 701...

Abstract

The invention discloses a preparation device for gallium nitride thin film, specifically relates to the technical field of gallium nitride thin film preparation, comprising a preparation chamber and an evaporation chamber, the evaporation chamber is fixedly connected to the bottom end inside the preparation chamber, and the evaporation chamber A quartz crucible is fixedly connected inside, and a heating wire is fixedly connected inside the quartz crucible, an ionization chamber is fixedly connected to the top of the evaporation chamber, and an insulating structure is arranged on the outer wall of the preparation chamber. The present invention is provided with a cavity, a shell, a connecting rod, a nut, a through hole and thermal insulation rock wool. When in use, the nut and the through hole are used to fix the shell on the outside of the preparation bin. At this time, a gap is formed between the preparation bin and the shell. Cavity, and then fill the cavity with thermal insulation rock wool, using the thermal insulation performance of thermal insulation rock wool, this can avoid the rapid loss of heat inside the preparation chamber, so that the internal temperature of the preparation chamber can be kept stable, and the preparation of GaN thin films can be improved. the quality of.

Description

technical field [0001] The invention relates to the technical field of gallium nitride thin film preparation, in particular to a preparation device for gallium nitride thin film. Background technique [0002] Gallium nitride thin film is a compound of nitrogen and gallium. It is a semiconductor material with a direct energy gap. The preparation of gallium nitride thin film by ionized cluster beam deposition method is the simplest and most practical method for preparing gallium nitride thin film, but now Some gallium nitride thin film preparation devices have many problems and defects, so a new gallium nitride thin film preparation device is needed. [0003] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been resolved: [0004] (1) The traditional gallium nitride thin film preparation device is inconvenient to fix thin film sample holders of different sizes, and has poor applicability...
