Description

Technical Field

[0001] The present invention relates to the technical field of deposition equipment, and in particular to a vapor deposition system and a bearing component of the vapor deposition equipment. Background Art

[0002] Chemical vapor deposition (CVD) reaction equipment or atomic layer deposition (ALD) reaction equipment rotates the carrier plate (substrate support assembly) on which the processed substrate is placed during deposition, thereby providing a uniform deposition effect for the substrate. A typical vapor deposition reactor structure is a reaction chamber surrounded by the side walls of the reaction chamber, the reaction chamber includes an axis structure, and the substrate tray on which the substrate is placed is installed on the top of the axis structure. The top of the reaction chamber includes a gas shower head, which is used to uniformly inject the reaction gas from the reaction gas source into the reaction chamber to achieve the processing of the substrate. The bottom of the reaction chamber also includes a vacuum device to control the internal air pressure of the reaction chamber and to remove the waste gas generated during the reaction process.

[0003] For example, a Chinese invention patent with publication number CN118048623A discloses a carrier assembly of a vapor deposition device and a vapor deposition device, specifically comprising: a tray body capable of receiving radio frequency radiation to generate an induced current to heat a substrate, on which a plurality of tray positions are circumferentially arranged for placing substrates; a disc-shaped sub-tray for carrying substrates, which can be movably placed on the tray position and rotate around the central axis of the sub-tray; an annular step is arranged around the sub-tray, and its upper surface close to the sub-tray is configured to be lower than the upper surface of the sub-tray; a lifting pin that passes through the tray body and the annular step and can move between a high position and a low position, and whose upper surface is at least partially located under the substrate, for driving the substrate to move up and down when taking and placing the substrate.

[0004] The above solution has the following shortcomings in actual use:

[0005] This solution adopts the thin film deposition process of radio frequency induction heater. By increasing the volume of the annular step parts around the substrate, the heat conversion rate of radio frequency energy in the annular step is increased to prevent uneven film formation caused by too low temperature at the edge of the substrate. At the same time, lifting pins are set in the annular step to cooperate with the robot arm to realize the placement of substrates. In actual use, since multiple substrates are located on the same tray body, although the production efficiency is improved, it cannot ensure that each substrate can be evenly affected by the reaction substances, and mutual interference between substrates cannot be avoided.

The exhaust system 600 is used to remove waste gas and excess reaction gas generated during the reaction, maintain a stable pressure in the reaction chamber, and prevent waste gas from polluting the environment.

[0040] The working process of this embodiment is as follows: before starting the device, it is necessary to check each component of the device to ensure that the mechanical structure, electrical system, gas system, heating system, vacuum system, etc. of the device are in normal working condition, select appropriate sample materials and clean the samples, place the cleaned samples in the storage part, and under the action of cylinder 1 3, make the movable plate 2 fit with the reaction system 300, then control the actuator 9 to make the mounting disk 8 start to rotate, so that the conveying side of the conveying part is opposite to the through groove 20 of the corresponding storage part, and then the conveying part takes out the sample and places it on the carrier, control the cylinder 3 24 to make the baffle 22 block the through groove 20, start the reaction system 300, the gas system 400 and the vacuum system 500 through the control system 200, and perform vapor deposition.
