[0044] In other embodiments, when the heat conducting member 2000 is inserted into the accommodating cavity 1140 , the heat conducting member 2000 is at least partially in contact with the first supporting portion 1110 or the second supporting portion 1130 .

[0045] See also Figure 2 and Figure 5In some embodiments, the heat conducting member 2000 includes a first contact surface 2100 and a second contact surface 2200 disposed opposite to each other.

The second enclosing portion 1180 and the third carrier portion 1170 form the open cavity 1161.

[0049] In some embodiments, the first supporting portion 1110 includes a first inner surface and a first outer surface. The mounting portion 1160 is disposed on the first outer surface along the second predetermined direction, and when the thermal conductive member 2000 is inserted into the accommodating cavity 1140, the first inner surface is partially aligned with the first contact surface 2100, thereby enabling the first contact surface 2100 to be aligned with the third supporting portion 1170.

[0050] In some embodiments, the second supporting portion 1130 includes a second inner surface and a second outer surface. When the heat conducting member 2000 is inserted into the accommodating cavity 1140 , the second inner surface is in contact with the second contact surface 2200 .

[0051] In some embodiments, the open cavity 1161 is cylindrical, and the central axis of the open cavity 1161 coincides with the central axis of the first bearing portion 1110 .

[0052] In other embodiments, the open cavity 1161 can also be adjusted to a quadrangular prism, a pentagonal prism, a hexagonal prism, etc. according to the shape of the sample, which will not be listed here one by one.

[0053] In some embodiments, the sample is inserted into the open cavity 1161 through the opening 1162, and the sample is at least partially exposed from the mounting portion 1160 to provide a space for taking and placing the sample, thereby improving the convenience of taking and placing the sample, thereby further improving the efficiency of the etching work.

[0054] See also Figure 2 and Figure 4 In some embodiments, the opening 1150 is provided on the first enclosure portion 1120 , and the shape of the opening 1150 matches the shape of the heat conducting member 2000 . When the heat conducting member 2000 is inserted into the accommodating cavity 1140 , the heat conducting member 2000 can block the opening 1150 .

[0055] In some embodiments, the opening 1150 faces the first preset direction, and the opening 1150 is arranged in an arc shape around the central axis of the open cavity 1161 .

The handle end 2400 is at least partially located outside the accommodating cavity 1140, and the end of the handle end 2400 is arc-shaped.

[0057] In some embodiments, the handle end 2400 is provided with a groove (not shown in the figure), which provides a handle position for removing and placing the thermal conductive member 2000. When the plug end 2300 is inserted into the accommodating cavity 1140, the handle end 2400 is at least partially located outside the accommodating cavity 1140, so that the groove is located outside the accommodating cavity 1140.

[0058] It can be understood that the groove is always located outside the accommodating cavity 1140 , so as to facilitate the extraction of the heat conducting member 2000 .

[0059] The carrier structure is placed in the chamber of the etching equipment, and the sample is inserted into the open cavity 1161. The relative position of the heat conductive member 2000 and the accommodating cavity 1140 can be adjusted to achieve fine-tuning of the sample temperature. When the heat conductive member 2000 is inserted into the accommodating cavity 1140, the first contact surface 2100 is in contact with the third bearing portion 1170, and the second contact surface 2200 is in contact with the second inner surface, thereby accelerating the heat conduction speed between the first bearing portion 1110 and the second bearing portion 1130. When the heat conductive member 2000 is removed from the accommodating cavity 1140, the heat conduction effect between the first bearing portion 1110 and the second bearing portion 1130 can be weakened. The present application achieves fine-tuning of the sample temperature by adjusting the relative position of the heat conductor 2000 and the accommodating cavity 1140, eliminating the step of adjusting the temperature setting of the equipment chamber, reducing energy consumption during the etching process, lowering costs, and improving the efficiency of the sample temperature regulation during the etching process, thereby improving the convenience of the sample temperature regulation and improving the efficiency of the etching work.
