Abstract

[0002] In the field of semiconductor thin film deposition, ultraviolet (UV) curing equipment utilizes UV irradiation to effectively improve film performance. However, prolonged UV irradiation can easily lead to the formation of E′ core (≡Si·) defects in the quartz window of the optical lens within the process chamber. Unpaired electrons within these E′ cores can absorb photons of a specific wavelength and transition to the conduction band, generating an absorption band centered at a wavelength of 200–300 nm (e.g., 215 nm). This results in a significant decrease in the UV transmittance of the quartz window. Therefore, existing UV curing equipment generally requires periodic disassembly and replacement of the quartz window to ensure normal equipment operation.

To provide a thorough understanding of the invention, many specific details will be included in the following description. The invention may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description.

Therefore, the first components, regions, layers, and / or parts discussed below may be referred to as second components, regions, layers, and / or parts without departing from some embodiments of the present invention.
[0041] As mentioned above, existing UV curing machines generally require regular disassembly and replacement of the quartz window to ensure normal operation of the equipment. As a result, they have the drawbacks of complex processes and long maintenance cycles, and are prone to external contamination entering the process chamber.
[0042] To overcome the aforementioned deficiencies in the existing technology, this invention provides an ultraviolet curing machine, a control method for the ultraviolet curing machine, and a computer-readable storage medium. This allows for in-situ hydrogen permeation treatment of the quartz window without disassembly, utilizing the existing temperature and pressure control modules of the ultraviolet curing machine. This extends the service life of the quartz window, improves the machine's efficiency, and enhances its working quality.
[0043] In some non-limiting embodiments, the control method for the ultraviolet curing machine provided in the second aspect of the present invention can be implemented based on the ultraviolet curing machine provided in the first aspect of the present invention. Specifically, the ultraviolet curing machine may be equipped with a memory and a processor. The memory includes, but is not limited to, the computer-readable storage medium provided in the third aspect of the present invention, on which computer instructions are stored. The processor is connected to the memory and configured to execute the computer instructions stored in the memory to implement the control method for the ultraviolet curing machine of the second aspect of the present invention.
[0044] Please refer to the details. Figure 1 and Figure 2 . Figure 1 A schematic diagram of the structure of a UV curing machine provided according to some embodiments of the present invention is shown. Figure 2 A schematic diagram of a hydrogen pipeline provided according to some embodiments of the present invention is shown.
[0045] like Figure 1 and Figure 2As shown, the UV curing machine includes a process chamber 10 and a hydrogen pipeline 20. The process chamber 10 includes a quartz window 101, a pressure control module 102, a temperature control module, a UV light source 104, and a reflector 105. The quartz window 101 encloses the upper space of the process chamber 10 and allows UV light provided by the upper UV light source 104 and / or reflector 105 to pass through the quartz window 101 and irradiate the sample inside the process chamber 10 for UV curing. The temperature control module and pressure control module 102 provide a corresponding first temperature and first pressure process environment during the UV curing process of the sample, and a corresponding second temperature and second pressure process environment during the hydrogen permeation process of the quartz window 101. The UV light source 104 is positioned above the quartz window 101 and provides first UV light to the sample in the process chamber 10 for UV curing of the deposited film. The reflector 105 surrounds the upper part of the ultraviolet light source 104 and is used to reflect the second ultraviolet light emitted by the ultraviolet light source 104 toward the sample for ultraviolet curing of the film deposited on it. The first end of the hydrogen conduit 20 is connected to the hydrogen source 30, and the second end is connected to the process chamber 10, for supplying hydrogen to the process chamber 10 during the hydrogen permeation process of the quartz window 101.
[0046] Furthermore, in some embodiments, the temperature control module includes a heating plate 1031 and a heating jacket 1032. The heating plate 1031 is located inside the process chamber 10 and is used to hold and heat the sample for ultraviolet curing. The heating jacket 1032 is located before the process chamber 10 and surrounds the hydrogen pipeline 20 for preheating the hydrogen introduced into the process chamber 10 for hydrogen permeation of the quartz window 101.
[0047] In addition, such as Figure 2 As shown, the hydrogen pipeline 20 may include a manual valve 201 and a filter 202. The manual valve 201 is used to close the hydrogen pipeline 20 during the UV curing process and to open the hydrogen pipeline 20 during the hydrogen permeation process. The filter 202 is used to pre-treat the hydrogen entering the process chamber 10 to prevent impurities from contaminating the process chamber 10.
[0048] Furthermore, in some embodiments, the hydrogen pipeline 20 may preferably include a diaphragm valve 203, a pressure gauge 204, a pressure regulator 205, and a mass flow controller 206, for adjusting the pressure and flow rate of the hydrogen entering the process chamber 10 to meet the requirements of the hydrogen permeation process.
[0049] Furthermore, in some embodiments, the curing machine may also include a counter, a timer, and / or a sensor. Here, the counter is used to count the number of times the UV curing process is performed, and triggers the hydrogen permeation process when the number reaches a preset threshold (e.g., 5 to 100 times). The timer is used to count the time elapsed since the last hydrogen permeation process, and triggers the hydrogen permeation process when it reaches a preset time threshold (e.g., 300 to 500 hours). The sensor is used to monitor the transmittance of the quartz window 101, and triggers the hydrogen permeation process when the transmittance of the quartz window 101 is lower than a preset transmittance threshold (e.g., 70% to 80%).
[0050] The working principle of the aforementioned UV curing machine will be described below with reference to some embodiments of wafer position detection methods. Those skilled in the art will understand that these embodiments of the UV curing machine control methods are merely non-limiting implementations provided by the present invention, intended to clearly demonstrate the main concepts of the invention and provide specific solutions convenient for public implementation, rather than limiting all functions or operating modes of the UV curing machine. Similarly, the control methods of this UV curing machine are also merely non-limiting implementations provided by the present invention, and do not constitute a limitation on the executing entity or execution order of each step in these UV curing machine control methods.
[0051] Please refer to the reference. Figures 1-3 , Figure 3 A control method for a UV curing machine according to some embodiments of the present invention is shown.
[0052] like Figures 1-3 As shown, during the operation of the UV curing machine, the UV curing machine can first provide a first temperature and first pressure process environment to the sample in the process chamber 10 through its temperature control module (e.g., heating plate 1031) and pressure control module 102, and provide ultraviolet light to it through the ultraviolet light source 104 and the reflection device 105 to perform ultraviolet curing process on the film deposited on the sample.
[0053] Meanwhile, in some embodiments, the UV curing machine can preferably use the counters, timers and / or sensors configured therein to monitor the state of the quartz window 101 in real time and determine the timing of triggering the hydrogen permeation process based on the trigger signals provided therein.
[0054] For example, a UV curing machine can use a counter to count the number of times the UV curing process is performed, and trigger a hydrogen permeation process when the number of times reaches a preset threshold (e.g., 5 to 100 times).
[0055] For example, a UV curing machine can use a timer to count the time elapsed since the last hydrogen permeation process, and trigger the hydrogen permeation process when it reaches a preset time threshold (e.g., 300-500 hours).
[0056] For example, the UV curing machine can monitor the transmittance of the quartz window 101 via a sensor, and trigger the hydrogen permeation process when the transmittance of the quartz window 101 is lower than a preset transmittance threshold (e.g., 70% to 80%).
[0057] Subsequently, in response to the trigger signals provided by the aforementioned counters, timers, and sensors, and / or the trigger commands provided by the user, the UV curing machine can remove the sample from the process chamber and switch the process mode. It provides a second temperature and a second pressure process environment to the quartz window 101 in the process chamber 10 via the temperature control module (e.g., heating plate 1031) and the pressure control module 102, and provides hydrogen at the corresponding temperature to the process chamber 10 via the temperature control module (e.g., heating jacket 1032) and the hydrogen pipeline 20 to perform an in-situ hydrogen permeation process on the quartz window 101 without disassembly.
[0058] Specifically, in the first stage of the hydrogen permeation process, the UV curing machine can first control the hydrogen pipeline 20 to supply hydrogen to the process chamber 10 at a preset first flow rate (e.g., 400-6000 sccm), control the pressure control device 102 to control the gas pressure in the process chamber 10 to a second pressure (e.g., 5 atm), and control the temperature control device to control the temperature in the process chamber 10 to a second temperature (e.g., 200-500°C).
[0059] Subsequently, in response to the first stage lasting for a preset first duration (e.g., 80–120 hours), the UV curing machine can determine that the first stage of the hydrogen permeation process has been completed and begin the second stage of the hydrogen permeation process. Then, in the second stage of the hydrogen permeation process, the UV curing machine can control the hydrogen pipeline 20 to reduce the hydrogen flow rate into the process chamber 10 to a preset second flow rate (e.g., 300–2000 sccm), and control the pressure control device 102 to reduce the gas pressure in the process chamber 10 to a preset third pressure (e.g., 3 atm).
[0060] Subsequently, in response to the second stage lasting for a preset second duration (e.g., 400-800 hours), the UV curing machine can determine that the hydrogen permeation process on the quartz window 101 has been completed.
[0061] Therefore, compared to existing technologies that require disassembling the quartz window 101 and then using specialized equipment for hydrogen permeation, this invention utilizes the hydrogen pipeline 20 added to the UV curing machine to introduce hydrogen into the process chamber 10. By using the existing pressure control module 102 and temperature control module of the UV curing machine, the pressure and temperature of the gas within the chamber are precisely controlled, allowing for direct, in-situ hydrogen permeation of the quartz window 101 without disassembly. This increases the hydrogen molecule content in the quartz window 101 glass to 3 × 10⁻⁶. 18 molecules / cm 3 It restores the transmittance of the quartz window 101, which has decreased transmittance, to more than 86% at wavelengths of 200–300 nm (e.g., 215 nm).
[0062] In summary, the present invention provides an ultraviolet curing machine, a control method for the ultraviolet curing machine, and a computer-readable storage medium, all of which can utilize the existing temperature control module and pressure control module of the ultraviolet curing machine to perform hydrogen permeation treatment on its quartz window 101 without disassembly, thereby extending the service life of the quartz window, improving the working efficiency of the machine, and enhancing the working quality of the machine.
