Description

Technical Field

[0001] This utility model belongs to the field of semiconductor processing technology, specifically relating to a tooling for loading and unloading semiconductor components. Background Technology

[0002] In the semiconductor manufacturing field, the electrostatic chuck (ESC), as a core component of wafer processing, directly affects the vacuum sealing performance and process stability of the equipment when assembled with the sealing ring. Since the ESC and sealing ring are mostly interference fits, especially for specialized semiconductor sealing rings used in ultra-high vacuum environments, traditional manual assembly methods struggle to ensure concentricity. This challenge directly leads to inaccurate sealing ring assembly, affecting the overall product performance and sealing effect. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the prior art, the present invention provides a tooling for loading and unloading semiconductor components to solve the problems in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A tooling for loading and unloading semiconductor components includes an inner stepped sealing ring, on which a limiting arc block is detachably installed, and a stepped guide ring is connected to the inner ring surface of the inner stepped sealing ring. The inner stepped sealing ring, the limiting arc block, and the stepped guide ring are all coaxially arranged.

[0005] Furthermore, multiple limiting arc-shaped blocks are detachably installed on the inner step sealing ring along the circumferential direction. The multiple limiting arc-shaped blocks are evenly distributed and together form an annular limiting structure coaxial with the inner step sealing ring.

[0006] Furthermore, all of the aforementioned limiting arc-shaped blocks are detachably mounted on the inner circumferential surface of the inner step sealing ring using screws.

[0007] Furthermore, the top surface of the base of the stepped guide ring is coplanar with the top surface of the base of the inner stepped sealing ring.

[0008] Furthermore, the height of the inner step sealing ring protrusion is greater than the height of the step guide ring protrusion.

[0009] Furthermore, the height of the limiting arc block is greater than the height of the protruding portion of the step guide ring.

[0010] Furthermore, the height of the protruding portion of the inner stepped sealing ring is greater than the height of the limiting arc-shaped block.

[0011] Furthermore, the protruding portion of the inner stepped sealing ring is provided with multiple through grooves along the circumferential direction, and the multiple through grooves are distributed at equal intervals.

[0012] Compared with the prior art, this utility model has the following advantages: 1. By using the coaxial design of the inner stepped sealing ring, the limiting arc block and the stepped guide ring, a unified reference axis is established structurally, solving the problem of concentricity deviation between the sealing ring and ESC in manual assembly; 2. Through the progressively increasing gradient design of the inner stepped sealing ring, the limiting arc block, and the stepped guide ring, a multi-layered stepped protection is formed, which gradually offsets the interference force, avoids excessive local compression of the sealing ring, and ensures the sealing effect. 3. The detachable design of the limit arc block, which is fixed by screws, facilitates the adaptation to different specifications of ESC and the replacement of worn parts, making maintenance and replacement easier and reducing tooling costs.

Detailed Implementation

[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0017] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: like Figure 1-4 As shown, this utility model provides a tooling for loading and unloading semiconductor components, comprising an inner stepped sealing ring 1, a limiting arc block 2 detachably mounted on the inner stepped sealing ring 1, and a stepped guide ring 3 connected to the inner ring surface of the inner stepped sealing ring 1. The inner stepped sealing ring 1, the limiting arc block 2, and the stepped guide ring 3 are all coaxially arranged, with the stepped guide ring 3 serving as a guide to guide the sealing ring to accurately enter the position. Through the coaxial design of the inner stepped sealing ring 1, the limiting arc block 2, and the stepped guide ring 3, the structural design avoids the problem of difficulty in ensuring the concentricity of the sealing ring and ESC (electrostatic chuck) during manual assembly of the sealing ring. Furthermore, the limiting arc block 2 is detachable, and when the limiting arc block 2 wears out due to long-term use, it can be disassembled and replaced separately. When installing sealing rings for different specifications of ESCs, the limiting arc block 2 can be disassembled separately before installing the sealing ring, without replacing the entire inner stepped sealing ring 1.

[0019] Among them, multiple limiting arc blocks 2 are detachably installed on the inner step sealing pressure ring 1 along the circumferential direction. The multiple limiting arc blocks 2 are evenly distributed and together form an annular limiting structure coaxial with the inner step sealing pressure ring 1, which forms a uniform radial constraint on the sealing ring and prevents the sealing ring from tilting during the assembly process.

[0020] Among them, multiple limiting arc-shaped blocks 2 are detachably installed on the inner circumferential surface of the inner step sealing ring 1 by screws 4.

[0021] Among them, the top surface of the base of the stepped guide ring 3 is coplanar with the top surface of the base of the inner stepped sealing ring 1, ensuring that the installation reference of the tooling and ESC are consistent.

[0022] Among them, the height of the protruding part of the inner step sealing ring 1 is greater than the height of the protruding part of the step guide ring 3. The protruding part of the inner step sealing ring 1 preferentially cooperates with the ESC positioning to form a step-type protection structure to avoid the sealing ring being excessively squeezed.

[0023] The height of the limiting arc block 2 is greater than the height of the protruding part of the stepped guide ring 3, forming a stepped protective structure to prevent the sealing ring from being excessively squeezed.

[0024] Among them, the height of the protruding part of the inner step sealing ring 1 is greater than the height of the limiting arc block 2, forming a multi-layer step design to ensure that the ESC, sealing ring and tooling structure are concentric.

[0025] The inner stepped sealing ring 1 has multiple through grooves 5 along the circumferential direction on its protruding part. The multiple through grooves 5 are evenly distributed. Pressing the inner stepped sealing ring 1 at the through grooves 5 can expel the air between the ESC and the inner stepped sealing ring 1 during interference fit. At the same time, it provides a small amount of elastic deformation space for the ring to adapt to interference fit fluctuations, avoid damage to the sealing ring by rigid fit, and ensure sealing effect.

[0026] Working Principle: The tooling uses the coaxiality of the inner stepped sealing ring 1, the limiting arc block 2, and the stepped guide ring 3 as the core reference to ensure that the axes of all components are consistent during assembly. During assembly, the stepped guide ring 3 first guides the sealing ring to accurately enter the preset position along the axis. Multiple equally spaced limiting arc blocks 2 form an annular limiting structure, applying uniform radial constraint to the sealing ring to prevent it from skewing during interference fit. The inner stepped sealing ring 1 is preferentially positioned and fitted with the ESC. Through the height gradient design of "inner stepped sealing ring 1 > limiting arc block 2 > stepped guide ring 3", a multi-layered stepped protection is formed, which gradually offsets the offset caused by interference force, ensuring that the sealing ring and ESC are concentrically fitted. At the same time, the detachable design of the limiting arc block 2, which is fixed by screws 4, facilitates the adaptation to different specifications of ESC and wear replacement. The through groove 5 of the inner stepped sealing ring 1 can discharge air during assembly and provide a small deformation space to avoid rigid compression damage to the sealing ring. Ultimately, it achieves accurate and stable assembly of the sealing ring under interference fit, improving the sealing effect.
