Description

Technical Field

[0001] This utility model relates to the field of PVD vacuum equipment technology, specifically to a controllable and efficient heating component for metal purification and evaporation heating. Background Technology

[0002] PVD vacuum equipment, or Physical Vapor Deposition (PVD) vacuum equipment, is a process device that uses a vacuum environment to heat and evaporate specific materials, causing them to vaporize and deposit onto a substrate surface for metal purification or thin film formation. Currently, it is mainly used for metal purification and evaporation technologies, playing a crucial role in several fields. For example, in the electronics industry, it is used to manufacture high-purity metal raw materials for semiconductor targets, semiconductor devices, and displays (such as OLED displays); in the optics field, it can be used to prepare optical coatings, improving the light transmittance and reflectivity of lenses; and in the packaging industry, it can achieve metallization layers to improve the barrier properties and aesthetics of packaging materials. During the evaporation process, the heating element is one of the core components, and its performance directly affects the evaporation rate, evaporation uniformity, and final quality of the evaporated material.

[0003] Evaporation systems typically operate under vacuum, usually between 0.1 Pa and 0.0005 Pa. Under vacuum, evaporation materials generally evaporate at saturated vapor pressure. The higher the evaporation temperature, the greater the evaporation rate, and the lower the vacuum pressure, the lower the evaporation temperature.

[0004] To ensure that the material evaporates onto the substrate as much as possible, it is desirable to minimize the evaporation of the metal during the heating process and only begin evaporation rapidly when the evaporation point is reached. This will maximize the material utilization efficiency.

[0005] Meanwhile, the evaporation temperature of metal materials is generally between 1200-1800℃. Apart from the heat required for evaporation, other heat is wasted through radiation or conduction. Especially during the heating process, the more heat is lost, the slower the temperature rises. Therefore, it is desirable to minimize energy loss during the heating process.

[0006] However, in most existing evaporation heating components, the upper part of the evaporator or evaporation boat directly uses a water-cooled plate as a baffle. Although the structure is simple, during the heating process, before reaching a stable working state, evaporation begins after reaching a certain temperature and vacuum. At this time, the metal is ineffectively evaporated and generally deposited on the upper water-cooled component, resulting in a large amount of heat waste and evaporation metal waste. At the same time, due to the different requirements of different industries for material performance, it is desirable to control the performance of the final product during the metal evaporation process, but the evaporation components do not have the function of automatically adjusting and controlling the evaporation area, which is not well matched for the research and development of metal materials. Utility Model Content

[0036] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 5 As shown, a controllable high-efficiency heating component in this embodiment of the present invention includes: a mounting plate 1, a heating component, a bottom heat insulation screen 7, a support frame 10 and an upper heat insulation screen 16. A support block 2 is provided in the middle of the inner side of the mounting plate 1, and a heat insulation block 3 is connected to the outer side of the upper end of the support block 2. A heating component is installed on the outer side of the upper end of the heat insulation block 3, and an evaporator 5 is provided inside the heating component.

[0038] The installation enclosure 1 consists of a water-cooled enclosure and a base plate, and both the water-cooled enclosure and the base plate have built-in water channels for water circulation.

[0039] The support block 2 is made of graphite and mainly serves to support the heat insulation block 3 and the heating components. The heat insulation block 3 mainly functions as insulation and heat insulation, and is made of insulating and heat-insulating ceramic material with a temperature exceeding 1600℃.

[0040] The heating assembly includes a first heater 4 and a second heater 25. The first heater 4 is installed on the upper outer side of the heat insulation block 3, and the second heater 25 is modularly installed inside the first heater 4. The connection between the first heater 4 and the second heater 25 is connected by a combination of graphite bolts. A pre-melting groove 6 is installed on the upper left side of the first heater 4, and the right end of the pre-melting groove 6 extends to the upper left side of the evaporator 5.

[0041] The heating components are made of graphite and feature a modular design. The first heater 4 is an integral structure, while the second heater 25 is modular for easy adjustment. Adjusting the size of the second heater 25 allows for adjustment of the number and size of the evaporators 5. Currently, the graphite material is 2 meters long. When the heating components exceed two meters, a modular design is adopted, and they are assembled using graphite bolts.

[0042] A bottom heat insulation screen 7 is installed on the inner side of the base plate. Side heat insulation screens 8 are provided on both the left and right sides of the inner wall of the water-cooled enclosure. Fixing screws 9 are provided at the connection between the water-cooled enclosure and the side heat insulation screens 8. An upper heat insulation screen 16 is fixedly installed on the outer side of the lower end of the second transmission component. The upper heat insulation screen 16 is located directly above the evaporator 5.

[0043] Among them, the bottom heat insulation screen 7, the side heat insulation screen 8, and the upper heat insulation screen 16 are all composed of all-metal reflective screens, and the metal used is composed of metal strips such as tungsten and molybdenum. At the same time, the metal screen adopts a modular design and is connected to the water-cooled mounting plate 1 by hanging. The number of all-metal reflective screens is more than five, and the spacing between the layers of all-metal reflective screens is 3-6mm. High-temperature ceramic heat insulation rings are used to determine the spacing and realize the positioning of the screens. Meanwhile, the fixing screws 9 are embedded parts, generally made of tungsten, molybdenum and alloys, which are connected through the bolt holes prefabricated on the mounting plate 1 and serve to hang and fix the metal reflective screen assembly.

[0044] A support frame 10 is fixedly installed on the outer surface of the mounting plate 1. A first transmission component is installed on the upper end of the support frame 10, and a second transmission component, also located on the upper end of the support frame 10, is provided on the lower side of the first transmission component.

[0045] The first transmission assembly includes a first guide rail 11, a first slider group 12, and a second mounting block 17. The first guide rail 11 is disposed on the upper end of the support frame 10. The first slider group 12 is adapted to be installed on the outer side of the upper end of the first guide rail 11. The second mounting block 17 is fixedly installed inside the first slider group 12. A ramp is provided in the middle of the first guide rail 11. A roller for movement is installed inside the lower end of the first slider group 12.

[0046] The second transmission assembly includes a second guide rail 13, a second slider group 14, and a first mounting block 15. The second guide rail 13 is mounted on the upper end of the support frame 10, and the second slider group 14 is adapted to be mounted on the outer side of the upper end of the second guide rail 13. The first mounting block 15 for fixing the upper heat insulation screen 16 is fixedly installed inside the second slider group 14. A ramp is provided in the middle of the second guide rail 13, and a roller for movement is installed inside the lower end of the second slider group 14.

[0047] A first water-cooled shielding plate 18 is installed on the left side of the first transmission assembly, and a second water-cooled shielding plate 19 is installed on the right side of the first transmission assembly.

[0048] The first guide rail 11 and the second guide rail 13 are two separate sets, allowing for the independent switching of the upper heat insulation screen 16, the first water-cooled shielding plate 18, and the second water-cooled shielding plate 19. Simultaneously, the first slider group 12 and the second slider group 14 contact the first guide rail 11 and the second guide rail 13 respectively via rollers. A drive component is provided on the outer side of the rollers, facilitating the movement of the first slider group 12 and the second slider group 14 according to the shape of the first guide rail 11 and the second guide rail 13. Furthermore, the inclination angle of the inner slope of the second guide rail 13 is greater than that of the inner slope of the first guide rail 11, allowing for height adjustment during movement.

[0049] There is a certain distance between the upper end of the upper heat insulation screen 16 and the first water-cooled shielding plate 18 and the second water-cooled shielding plate 19, so as to avoid the upper heat insulation screen 16 being affected by the top of the water-cooled enclosure and the first water-cooled shielding plate 18 and the second water-cooled shielding plate 19 when it is opened.

[0050] The two sets of ramps in the first guide rail 11 are arranged in opposite directions, and the two sets of ramps in the second guide rail 13 are arranged in the same direction, so as to facilitate the opening and closing of the upper heat insulation screen 16, the first water-cooled shielding plate 18, and the second water-cooled shielding plate 19 respectively through the first transmission component and the second transmission component.

[0051] A wire feeding roller 20 is rotatably mounted on the middle left side of the water-cooled enclosure, and a servo drive wheel set 21, which is also located inside the enclosure 1, is provided on the upper right side of the wire feeding roller 20. A wire straightening wheel set 22 is mounted on the upper right side of the servo drive wheel set 21, and a wire feeding tube 23 is installed through the inside of the left side wall of the enclosure 1.

[0052] The feed roller 20 is equipped with a drive motor at its rear, which rotates the feed roller 20 within the mounting plate 1. This enables precise feeding of the wire through the servo drive wheel set 21 and the wire straightening wheel set 22. The feed tube 23 is arc-shaped, and its shape coincides with the straightening center of the servo drive wheel set 21 and the wire straightening wheel set 22 to achieve smooth feeding. Simultaneously, the speed of the wire can be adjusted by driving the servo motor through an external control interface, allowing for precise feeding of various metal raw materials.

[0053] The wire can be fed into the pre-melting tank 6 first, where it is heated and turns into a liquid. When the liquid level exceeds the feeding height of the pre-melting tank 6, it overflows and replenishes the material to the evaporator 5. For low melting point metals below 800℃, the wire can be fed directly into the evaporator 5.

[0054] A conductive foil strip 24 is installed through the right side of the water-cooled enclosure, and the conductive foil strip 24 is connected to the lead wire of the first heater 4.

[0055] The conductive foil strip 24 is flexibly adjustable to accommodate the thermal expansion of the first heater 4 during heating. The mounting plate 1 has an opening at the lead-out end of the first heater 4, and the opening is insulated to reduce heat loss.

[0056] A thermocouple 26 is installed through the middle of the right side of the water-cooled enclosure, and the left end of the thermocouple 26 extends into the first heater 4.

[0057] Thermocouple 26 is used to measure the temperature of the first heater 4. The collected temperature is interconnected with the wire feeding system, the first water-cooled shielding plate 18 and the second water-cooled shielding plate 19 through the control system. When the external pressure and temperature are reached, the opening and closing and position adjustment of the first water-cooled shielding plate 18, the second water-cooled shielding plate 19 and the upper heat insulation screen 16 are automatically controlled.

[0058] Working principle

[0059] First, the evaporation temperature is set to 1000℃ and the vacuum degree is 0.05pa. Some of the evaporating metal is pre-filled into the evaporator 5. The evaporation system evacuates the entire environment and sets the heating curve. The first heater 4 and the second heater 25 start heating. At this time, the upper heat shield 16, the first water-cooled shield 18 and the second water-cooled shield 19 are in the closed state. When the thermocouple 26 detects that the temperature reaches 1000 degrees Celsius, the second transmission component automatically receives the system command and starts the roller through the drive component, which drives the second slider group 14 and the first mounting block 15 to move the upper heat shield 16 out automatically. At this time, the first water-cooled shield 18 and the second water-cooled shield 19 are still closed, and only the first water-cooled shield 18 and the second water-cooled shield 19 are on the upper part of the evaporator 5. At this time, the temperature usually fluctuates. After the temperature stabilizes and the vacuum degree reaches 0.05 Pa, the first transmission component automatically receives the system command and starts the roller through the drive component. This drives the first slider group 12 and the second mounting block 17 to open the first water-cooled shielding plate 18 and the second water-cooled shielding plate 19, and the normal evaporation process begins, causing the metal to evaporate, vaporize, and deposit onto the surface of the substrate above.

[0060] When metals evaporate normally, metal vapor molecules may appear above the surface of the liquid metal. However, only a specific evaporation angle is usually selected as the effective evaporation area. Different metals generally have different evaporation angles. When this happens, the metal evaporation angle can be adjusted by controlling the opening distance of the first water-cooled shielding plate 18 and the second water-cooled shielding plate 19.

[0061] The evaporation rate of a metal under given conditions can be calculated, and there are currently many databases available to support this. For example, in the case above, assuming the evaporation rate of the metal at 1000℃ and a vacuum of 0.05 Pa is 10 g / s, the material in evaporator 5 will be the first to evaporate after normal operation begins. As the evaporation process progresses, the amount of metal in evaporator 5 decreases. If continuous evaporation is planned, evaporator 5 needs to be replenished. The evaporation rate of the metal is converted into the feeding speed of the wire feeding system. The wire is fed to the pre-melting tank 6 through the wire feeding roller 20, servo drive wheel set 21, wire straightening wheel set 22, and wire feeding tube 23 for melting. At this time, the temperature of the material in the pre-melting tank 6 is generally more than 50℃ lower than that of the material in evaporator 5. When the liquid level of the material in the pre-melting tank 6 exceeds the chute, evaporator 5 can be replenished.

[0062] After the evaporation process is completed, the wire feeding system stops feeding and reverses to take in the wire to prevent the wire from continuing to be heated and melting in the heating space. At the same time, the upper heat insulation screen 16 is closed through the second transmission component, and the heating power is reduced. After the temperature of the temperature measuring thermocouple 26 stabilizes, the heating power is turned off, and the first water-cooled shielding plate 18 and the second water-cooled shielding plate 19 are closed.

[0063] The above solution uses a full metal screen surrounding the evaporator. During the heating process, the upper heat insulation screen 16 is closed to form a relatively enclosed space, which greatly reduces the heat radiated by the evaporator 5 during the evaporation process and also reduces the waste of evaporating metal materials during the heating process.

[0064] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
