Abstract
Description
Technical Field
[0001] The present invention relates to the field of semiconductor manufacturing, and in particular to a platform-type constant temperature device suitable for semiconductor temperature calibration. Background Art
[0002] Temperature calibration is a critical step in ensuring product quality and performance during semiconductor manufacturing and testing. Precise temperature control directly impacts the physical and electrical properties of semiconductor materials, making it crucial to use efficient and reliable constant temperature equipment for temperature calibration.
[0003] Existing semiconductor temperature calibration equipment typically uses a constant temperature bath or dry-type furnace for temperature control calibration, making it impossible to perform large-scale calibration. Furthermore, most existing constant temperature baths or dry-type furnaces integrate the heating and cooling control structures in the same area. While this design simplifies the structure and operation of the equipment to a certain extent, it also brings many technical problems. The most significant problem is the mutual interference between the heating and cooling processes. In actual operation, the heating and cooling processes need to adjust the temperature quickly and accurately to meet the requirements of different semiconductor materials. However, because the heating and cooling control structures are located in the same area, they are prone to heat transfer interference when operating. When the heating device is operating, the heat generated may affect the effectiveness of the cooling device, resulting in reduced cooling efficiency; vice versa, this significantly increases the response time of the entire calibration process, affecting the accuracy and efficiency of the calibration.
[0004] Furthermore, when switching temperature modes (e.g., from heating to cooling), existing devices can take a long time to stabilize at the target temperature due to the interaction between the heating and cooling structures. In some cases, temperature fluctuations can occur, further impacting calibration reliability. This structural design reduces temperature control accuracy, and in severe cases, can prevent the expected calibration results from being achieved, thus affecting the performance of semiconductor products.

DETAILED DESCRIPTION
[0045] The following description is merely illustrative in nature and is not intended to limit the present disclosure, its applications, or uses. It should be understood that throughout the drawings, identical or similar reference numerals indicate identical or similar parts and features. The drawings merely schematically illustrate the concepts and principles of the embodiments of the present disclosure and do not necessarily depict the specific dimensions and proportions of the various embodiments of the present disclosure. Certain portions of certain drawings may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.
[0046] Example 1
[0047] like Figure 1-Figure 7 As shown, this embodiment provides a technical solution: a platform-type constant temperature device suitable for semiconductor temperature calibration, including a device body 1, a temperature increase control mechanism 5 and a temperature decrease control mechanism 7, wherein an operating table 2 is provided above the device body 1, a constant temperature calibration platform 200 is embedded in the surface of the operating table 2, an insulating sealed box 4 is provided above the operating table 2, and the insulating sealed box 4 covers the constant temperature calibration platform 200, the temperature increase control mechanism 5 is provided inside the device body 1, and is used to control the temperature increase of the constant temperature calibration platform 200, and the temperature decrease control mechanism 7 is provided inside the device body 1, and is used to control the temperature decrease of the constant temperature calibration platform 200;
[0048] The temperature increase control mechanism 5 and the temperature decrease control mechanism 7 are both supported and controlled by the support control mechanism 6. The temperature increase control mechanism 5 and the temperature decrease control mechanism 7 can be moved to a first position and a second position under the control of the support control mechanism 6. The first position is a temperature increase working position in which the temperature increase control mechanism 5 is horizontal, the temperature decrease control mechanism 7 is vertical, the upper portion of the temperature increase control mechanism 5 is in contact with the constant temperature calibration platform 200, and the temperature decrease control mechanism 7 is separated from the constant temperature calibration platform 200. The second position is a temperature decrease working position in which the temperature increase control mechanism 5 is vertical, the temperature decrease control mechanism 7 is horizontal, the temperature increase control mechanism 5 is separated from the constant temperature calibration platform 200, and the upper portion of the temperature decrease control mechanism 7 is in contact with the constant temperature calibration platform 200.
[0049] Working Principle: When using the device, the semiconductor to be calibrated is first placed on top of the constant temperature calibration platform 200, and then the thermally insulated sealed box 4 is closed. Then, according to the need for heating or cooling, the temperature control mechanism 5 and the temperature control mechanism 7 are controlled by the support control mechanism 6 to move the temperature control mechanism 5 and the temperature control mechanism 7 to the heating working position or the cooling working position, and the semiconductor temperature calibration operation can be carried out;
[0050] In summary: the device is a platform-type calibration, that is, a constant temperature calibration platform 200 is used to calibrate the temperature of the semiconductor. Therefore, the device can perform temperature calibration on multiple semiconductors at the same time, and the structures used for heating and cooling control in the device are independent of each other, that is, the temperature increase control mechanism 5 and the temperature reduction control mechanism 7 independently control the semiconductor to heat up or cool down. The two can quickly respond to temperature adjustment requirements without affecting each other, thereby improving the efficiency and accuracy of the calibration process and ensuring the quality of semiconductor products.
[0051] Specifically, the temperature increasing control mechanism 5 and the temperature decreasing control mechanism 7 are respectively located at symmetrical positions on both sides below the constant temperature calibration platform 200 , so that the temperature increasing control mechanism 5 and the temperature decreasing control mechanism 7 do not interfere with each other when switching positions.
[0052] Specifically, such as Figure 4-Figure 9 As shown, in order to realize the control of the temperature increase control mechanism 5 and the temperature decrease control mechanism 7, in this embodiment, two groups of support control mechanisms 6 are provided. The two groups of support control mechanisms 6 are symmetrically installed inside the device body 1. The support control mechanism 6 includes a column 600, a flip connection plate 601 and a position control motor 605. Among them, there are two columns 600, the two columns 600 are vertically arranged, the flip connection plate 601 is rotatably installed between the two columns 600, and the position control motor 605 is installed on the outside of one of the columns 600. The output shaft of the position control motor 605 is connected to the rotating shaft of the flip connection plate 601, so that the position control motor 605 can control the rotation of the flip connection plate 601;
[0053] The temperature increase control mechanism 5 and the temperature decrease control mechanism 7 are respectively mounted on two sets of flip connection plates 601 supporting the control mechanism 6, so that the temperature increase control mechanism 5 and the temperature decrease control mechanism 7 can follow the rotation and position change of the flip connection plates 601;
[0054] Based on this, when it is necessary to control the temperature rise through the temperature rise control mechanism 5, the temperature drop control mechanism 7 is in a vertical state and separated from the constant temperature calibration platform 200. The flip connection plate 601 on which the temperature rise control mechanism 5 is installed is rotated to the horizontal under the drive control of the position change control motor 605. That is, the position change control motor 605 is running, and the flip connection plate 601 on which the temperature rise control mechanism 5 is installed is driven by the rotating shaft to rotate 90°, so that it rotates from a vertical state to a horizontal state. At this time, the upper part of the temperature rise control mechanism 5 is in contact with the constant temperature calibration platform 200, and the temperature rise of the constant temperature calibration platform 200 can be controlled by the temperature rise control mechanism 5. Conversely, when it is necessary to When the temperature reduction control mechanism 7 controls the temperature reduction, the flip connecting plate 601 on which the temperature increase control mechanism 5 is installed is driven by the position control motor 605 and rotates from a horizontal state to a vertical state, and is separated from the constant temperature calibration platform 200. The flip connecting plate 601 on which the temperature reduction control mechanism 7 is installed is driven and controlled by the position control motor 605 and rotates to a horizontal state. At this time, the top of the temperature reduction control mechanism 7 contacts the constant temperature calibration platform 200, and the temperature reduction control mechanism 7 can be used to control the constant temperature calibration platform 200 to cool down. Therefore, there will be no mutual interference between the temperature increase control mechanism 5 and the temperature reduction control mechanism 7, thereby ensuring the response efficiency of heating and cooling.
[0055] Specifically, such as Figure 4-Figure 9 As shown, in order to make the cooling control mechanism 7 and the heating control mechanism 5 transfer heat faster in the process of controlling the constant temperature calibration platform 200 to cool down or heat up, in this embodiment, a guide groove 603 is opened in the vertical direction at the top of the column 600, and a slide 604 is slidably installed in the guide groove 603. The two ends of the flip connecting plate 601 are respectively rotatably installed on the inner side of the slide 604 in the two columns 600, so that the flip connecting plate 601 can follow the slide 604 and slide in the vertical direction within the range of the guide groove 603. A cylinder 602 is installed at the bottom of the column 600 to push the slide 604 to move up and down. The bottom of the operating table 2 is located below the constant temperature calibration platform 200 and is provided with a docking space 202. The cooling control mechanism 7 and the heating control mechanism 5 can be lifted and lowered so that the upper surface is docked into the docking space 202 and fits with the bottom of the constant temperature calibration platform 200. This structural arrangement makes the cooling control mechanism 7 and the heating control mechanism 5 respond faster when controlling the constant temperature calibration platform 200 to cool down or heat up.
[0056] Specifically, such as Figure 4-Figure 9As shown, in order to further improve the temperature reduction control mechanism 7 and the temperature increase control mechanism 5 so that they can fully contact the constant temperature calibration platform 200 when they are docked in the docking space 202, in this embodiment, the bottom of the slide 604 is connected to the connecting plate 607 through a spring 606, and the front end of the piston rod of the cylinder 602 is fixedly connected to the connecting plate 607 through a bolt. Based on this, when the cylinder 602 pushes the slide 604 to rise, so that the temperature reduction control mechanism 7 and the temperature increase control mechanism 5 are docked in the docking space 202, under the elastic force of the spring 606, the temperature reduction control mechanism 7 and the temperature increase control mechanism 5 can fully contact the constant temperature calibration platform 200, thereby improving the temperature conduction speed and efficiency.
[0057] Specifically, such as Figure 6 and Figure 11 As shown, in order to ensure the stability of the cooling control mechanism 7 and the temperature increasing control mechanism 5 when the cooling control mechanism 7 and the temperature increasing control mechanism 5 are docked to the docking space 202 and to avoid the situation where the cooling control mechanism 7 and the temperature increasing control mechanism 5 are excessively squeezed and damaged as a result, in this embodiment, a snap-fit assembly 8 is provided at both ends of the docking space 202 inside the equipment main body 1. The snap-fit assembly 8 can snap-fit and fix the cooling control mechanism 7 and the temperature increasing control mechanism 5 when they are docked into the docking space 202. The snap-fit assembly 8 includes a U-shaped frame 800 and a pressure plate 805, wherein the U-shaped frame 800 is fixedly mounted on the bottom of the operating table 2, and a shaft 802 is rotatably mounted on the inner side of the U-shaped frame 800, and a snap-fit control motor 801 is fixedly mounted on one side of the U-shaped frame 800, and the output shaft of the snap-fit control motor 801 is connected to the pressure plate 805. The shaft 802 is connected for transmission, and the pressure plate 805 is fixedly mounted on the shaft 802 through the U-shaped connecting rod 803, so that the pressure plate 805 can be controlled to rotate by the shaft 802. Specifically, in order to improve the fastening stability of the fastening assembly 8, a plurality of U-shaped frames 800 are provided in the fastening assembly 8, and the plurality of U-shaped frames 800 are arranged equidistantly in the horizontal direction, and the shafts 802 on the plurality of U-shaped frames 800 are connected, and the fastening control motor 801 is installed on the U-shaped frame 800 at the edge, so that when the cooling control mechanism 7 or the heating control mechanism 5 is docked to the docking space 202, the plurality of U-shaped frames 800 in the fastening assembly 8 can simultaneously lock the edges of the cooling control mechanism 7 and the heating control mechanism 5, thereby improving the stability of the cooling control mechanism 7 and the heating control mechanism 5, thereby improving the temperature conduction effect;
[0058] The surface of the pressure plate 805 is embedded with a pressure sensor 804. When the buckle control motor 801 is running, the pressure plate 805 can be driven to rotate through the shaft 802 and the U-shaped connecting rod 803 to reach the locking position and the unlocking position. The locking position is that the pressure plate 805 is attached to the bottom of the temperature control mechanism 7 or the temperature control mechanism 5, and the two ends of the temperature control mechanism 7 or the temperature control mechanism 5 are tightly fixed. The unlocking position is that the pressure plate 805 is away from the temperature control mechanism 7 or the temperature control mechanism 5, so that the temperature control mechanism 7 or the temperature control mechanism 5 is unlocked. In this way, the temperature control mechanism 7 and the temperature control mechanism 5 are stable when the temperature control mechanism 7 and the temperature control mechanism 5 are docked to the docking space 202, and the pressure sensor 804 can sense the pressing force value of the pressure plate 805 on the temperature control mechanism 7 and the temperature control mechanism 5, so as to avoid the situation where the temperature control mechanism 7 and the temperature control mechanism 5 are over-extruded and damaged, thereby forming an "element autonomous protection mechanism". The system improves the service life of the equipment. Specifically, the pressure sensor 804 is connected to the external host device, and the monitoring pressure threshold of the pressure sensor 804 is set by the host. The pressure sensor 804 transmits the pressure value to the host in real time. When the pressure value of the pressure sensor 804 reaches the threshold, the host controls the buckling control motor 801 to stop rotating. At the same time, it is ensured that when the cooling control mechanism 7 and the heating control mechanism 5 are docked to the docking space 202, the cooling control mechanism 7 and the heating control mechanism 5 can fully contact the constant temperature calibration platform 200, thereby achieving the effect of improving temperature conduction. It should also be noted that: since the buckling component 8 can buckle and fix the cooling control mechanism 7 or the heating control mechanism 5 when it is docked to the docking space 202, the displacement control motor 605 used to control the rotation of the cooling control mechanism 7 or the heating control mechanism 5 can be shut down to avoid it being in an over-pressure state for a long time and causing overheating damage, thereby ensuring its service life.
[0059] Example 2
[0060] like Figure 1-Figure 7 As shown, this embodiment provides a technical solution: Based on Example 1, in order to achieve temperature reduction control, the temperature reduction control mechanism 7 includes a refrigerant carrier plate 700 and a first heat conducting plate 701, wherein one side of the refrigerant carrier plate 700 is fixed to the flip connecting plate 601, and a refrigerant channel 703 for circulating the refrigerant is provided inside the refrigerant carrier plate 700. The first heat conducting plate 701 is embedded above the refrigerant carrier plate 700 and covers the refrigerant channel 703;
[0061] The refrigerant channel 703 adopts a continuous S-shaped structure. Based on this, when the refrigerant medium flows in the refrigerant channel 703, since the first heat conduction plate 701 is in direct contact with the constant temperature calibration platform 200, the refrigerant can exchange heat with the constant temperature calibration platform 200 to achieve temperature reduction control of the constant temperature calibration platform 200.
[0062] Specifically, the temperature-lowering control mechanism 7 also includes a refrigerator 3, which is installed on the operating table 2. The refrigerator 3 is connected to the refrigerant channel 703 inside the refrigerant carrier plate 700 through the refrigerant conduit 300 and the refrigerant return pipe 301, respectively, to form a circulation loop, that is, the refrigerant of the refrigerator 3 is introduced into the refrigerant channel 703 through the refrigerant conduit 300, and then flows back to the refrigerator 3 through the refrigerant return pipe 301 to complete the refrigeration. It should be noted that the refrigerator 3 adopts a Stirling refrigerator.
[0063] Specifically, such as Figure 10 As shown, in order to achieve temperature rise control, in this embodiment, the temperature rise control mechanism 5 includes a heat source carrier plate 500, one side of the heat source carrier plate 500 is fixed on the flip connecting plate 601, a heating coil 503 is provided inside the heat source carrier plate 500, and a second heat conducting plate 502 is embedded in the upper surface of the heat source carrier plate 500, and the second heat conducting plate 502 covers the heating coil 503. Therefore, when the heating coil 503 is heated, since the second heat conducting plate 502 is in direct contact with the constant temperature calibration platform 200, the heat can be directly conducted to the constant temperature calibration platform 200, thereby achieving temperature rise control of the constant temperature calibration platform 200.
[0064] Specifically, such as Figure 3 、 Figure 4 、 Figure 6 、 Figure 10 As shown, in order to reduce energy dissipation and affect the calibration effect of the equipment, in this embodiment, the edge of the first heat conducting plate 701 is surrounded by a circle of first heat-resistant insulation frame 702, the edge of the second heat conducting plate 502 is surrounded by a circle of second heat-resistant insulation frame 501, and the edge of the constant temperature calibration platform 200 is surrounded by a circle of third heat-resistant insulation frame 201, wherein the first heat-resistant insulation frame 702, the second heat-resistant insulation frame 501 and the third heat-resistant insulation frame 201 are made of ceramic fiber, thereby achieving the effect of preventing heat dissipation.
