Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vacuum deposition coating, and particularly to a PECVD-magnetron sputtering co-deposition doped film device. Background Art
[0002] Both PECVD (Plasma Enhanced Chemical Vapor Deposition) and magnetron sputtering technologies are commonly used technical means in deposition coating. In the prior art, co-deposition devices that achieve co-deposition coating through PECVD and magnetron sputtering technologies generally fall into two approaches. One is to separately arrange a magnetron sputtering device and a PECVD device in a vacuum reaction chamber, but during the operation process, they are still used as two separate devices to successively use PECVD and magnetron sputtering technologies, so as to separately deposit coatings successively. The two devices are not truly integrated, and co-deposition coating cannot be achieved. The other is to integrate the PECVD and magnetron sputtering two devices into one and co-deposition coating can be achieved, but the plasma generated after the two systems are started and operated will interfere with each other, resulting in unstable film formation quality.
[0003] Moreover, in the existing magnetron sputtering technology, there is a lack of precise control means for target materials with a relatively fast sputtering rate, so it is difficult to regulate the content of target atoms in the deposited film, resulting in unstable sputtering rate and deposition uniformity of magnetron sputtering.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.
[0045] The following will describe in detail some embodiments of the present application in conjunction with the accompanying drawings. Without conflict, the features of the following embodiments can be combined with each other.
[0046] Please refer to Figures 1 to 3 , Figure 1 which is a schematic three-dimensional structure diagram of a PECVD-magnetron sputtering co-deposition doped film layer device provided by an embodiment of the present application, Figure 2 and is a partial schematic three-dimensional structure diagram of a PECVD-magnetron sputtering co-deposition doped film layer device provided by an embodiment of the present application, Figure 3 and is a schematic three-dimensional structure diagram of a magnetron sputtering mechanism provided by an embodiment of the present application.
[0047] As Figures 1 to 3 shown, the PECVD-magnetron sputtering co-deposition doped film layer device 100 is provided with a substrate connection component 20 for fixing the substrate to be deposited. Moreover, the PECVD-magnetron sputtering co-deposition doped film layer device 100 further includes: a housing 10, a chemical vapor deposition mechanism 30, a magnetron sputtering mechanism 40, and a sputtering adjustment mechanism 50.
[0048] Among them, the housing 10 forms a receiving cavity 11. There is a gas supply mechanism 70 for introducing reaction gas in the receiving cavity 11. And the substrate connection component 20 is arranged in the receiving cavity 11 and is located at one end of the receiving cavity 11 close to the chemical vapor deposition mechanism 30.
[0049] The chemical vapor deposition mechanism 30 is at least partially received in the receiving cavity 11 and is used to perform ionization operation on the reaction gas introduced into the receiving cavity 11 to obtain plasma clusters, and to deposit the plasma clusters generated by ionization onto the target surface of the substrate to be deposited. It can be understood that the chemical vapor deposition mechanism 30 performs plasma-enhanced chemical vapor deposition on the substrate to be deposited to form a thin film on the target surface.
[0050] The magnetron sputtering mechanism 40 is at least partially received in the receiving cavity 11 and corresponds to the position of the substrate connection component 20 for fixing the substrate to be deposited. The magnetron sputtering mechanism 40 includes a radio frequency power supply, and a target is fixed at one end close to the substrate connection component 20. The radio frequency power supply can ionize the reaction gas in the receiving cavity 11 to form high-energy particles. The high-energy ions bombard the target, causing the target atoms to be sputtered out and sputter-deposited onto the target surface of the substrate to be deposited. It can be understood that the magnetron sputtering mechanism 40 performs magnetron sputtering deposition on the substrate to be deposited to obtain a thin film.
[0051] The sputtering adjustment mechanism 50 is arranged between the magnetron sputtering mechanism 40 and the substrate connection component 20 and is close to the end of the magnetron sputtering mechanism 40 where the target is fixed, and is used to adjust the flow rate of the target atoms output by the magnetron sputtering mechanism 40 to the target surface.
[0052] With such a setting, on the one hand, a chemical vapor deposition mechanism 30 and a magnetron sputtering mechanism 40 are provided in the accommodation cavity 11, so that during the process of performing PECVD on the target substrate of the substrate connection component 20 by the chemical vapor deposition mechanism 30, the magnetron sputtering mechanism 40 can perform co-deposition on the surface of the target substrate, so that particle doping can be performed by magnetron sputtering while performing PECVD; on the other hand, the sputtering adjustment mechanism 50 is arranged between the magnetron sputtering mechanism 40 and the substrate connection component 20, which is convenient for precisely controlling the deposition rate of the magnetron sputtering mechanism 40.
[0053] In some embodiments, the PECVD-magnetron sputtering co-deposition doping film device 100 has a switchable first working mode and second working mode.
[0054] Among them, in the first working mode, one of the chemical vapor deposition mechanism 30 and the magnetron sputtering mechanism 40 operates, that is, the PECVD-magnetron sputtering co-deposition doping film device 100 can independently operate the chemical vapor deposition mechanism 30 to perform plasma enhanced chemical vapor deposition on the target substrate, or independently operate the magnetron sputtering mechanism 40 to perform magnetron sputtering deposition on the target substrate.
[0055] In the second working mode, both the chemical vapor deposition mechanism 30 and the magnetron sputtering mechanism 40 operate, that is, during the process of performing plasma enhanced chemical vapor deposition on the target substrate by the chemical vapor deposition mechanism 30, the magnetron sputtering mechanism 40 can be simultaneously operated to output target atoms to the surface of the target substrate for co-deposition, so that particle doping can be performed by magnetron sputtering during the plasma enhanced chemical vapor deposition process, thereby changing the performance of the thin film.
[0056] For example, the PECVD-magnetron sputtering co-deposition doping film device 100 can prepare a diamond-like carbon film doped with Ag in the second working mode. By the gas supply mechanism 70, a certain proportion of CH4 and Ar are introduced into the accommodation cavity 11, and the chemical vapor deposition mechanism 30 is turned on to ionize CH4 to form C* and H*. Among them, C* deposits on the substrate to be deposited of the substrate connection component 20 to form a carbon film. While performing PECVD, the magnetron sputtering mechanism 40 is fixed with an Ag target and turned on. Ar is ionized into Ar by the radio frequency power supply * Ar * Under the magnetic field of the magnetron sputtering mechanism 40, the Ag target is bombarded, so that the Ag particles in the Ag target are sputtered towards the carbon film of the substrate to be deposited.
[0057] Under the co-deposition of the chemical vapor deposition mechanism 30 and the magnetron sputtering mechanism 40, a diamond-like carbon film doped with Ag is deposited on the substrate to be deposited, and the doping of Ag improves the optical and electrical properties of the diamond-like carbon film.
[0058] The setting of the two working modes not only enables the PECVD-magnetron sputtering co-deposition doping film device 100 to have higher process flexibility and scenario adaptation ability, can achieve a wider working range coverage through the switching of working modes, improve the practicability and utilization rate of the device, but also in the second working mode, the chemical vapor deposition mechanism 30 and the magnetron sputtering mechanism 40 can be co-deposited to change the performance of the thin film.
[0059] In some embodiments, the magnetron sputtering mechanism 40 includes a first magnetron sputtering component 42, a second magnetron sputtering component 43, and a third magnetron sputtering component 44, and their positions arranged in the accommodation cavity 11 can be different.
[0060] Among them, the first magnetron sputtering component 42 is used to output target atoms to the first area of the target surface of the substrate to be deposited, the second magnetron sputtering component 43 is used to output target atoms to the second area of the target surface of the substrate to be deposited, the third magnetron sputtering component 44 is used to output target atoms to the third area of the target surface of the substrate to be deposited, and the first area, the second area, and the third area of the target surface completely overlap.
[0061] With such an arrangement, it is ensured that the deposition areas of the first magnetron sputtering component 42, the second magnetron sputtering component 43, and the third magnetron sputtering component 44 are the same, thereby ensuring the uniformity and surface thickness consistency of the thin film formed on the target surface.
[0062] Moreover, the magnetron sputtering mechanism 40 can, according to the needs of deposition coating, only turn on and operate any number of magnetron sputtering components.
[0063] For example, the magnetron sputtering mechanism 40 can only turn on any one of the first magnetron sputtering component 42, the second magnetron sputtering component 43, and the third magnetron sputtering component 44, and not turn on the remaining two; it can also only turn on any two of the first magnetron sputtering component 42, the second magnetron sputtering component 43, and the third magnetron sputtering component 44, and not turn on the remaining one. The flexible use of multiple magnetron sputtering components can flexibly meet more usage situations, so that the magnetron sputtering mechanism 40 has more diverse usage scenarios and requirements.
[0064] The PECVD-magnetron sputtering co-deposition doping film device 100 includes a target magnetron sputtering component 41, and the target magnetron sputtering component 41 includes at least one of the first magnetron sputtering component 42, the second magnetron sputtering component 43, and the third magnetron sputtering component 44.
[0065] The sputtering adjustment mechanism 50 is disposed between the target magnetron sputtering assembly 41 and the substrate connection member 20, and closer to one end of the target magnetron sputtering assembly 41, and is used to adjust the flow rate of the target atoms output by the target magnetron sputtering assembly 41 to the target surface of the substrate to be deposited. Among them, the sputtering adjustment mechanism 50 can be set corresponding to a single magnetron sputtering assembly in the target magnetron sputtering assembly 41, or can be set corresponding to multiple magnetron sputtering assemblies in the target magnetron sputtering assembly 41 at the same time.
[0066] In this embodiment, the sputtering adjustment mechanism 50 is set corresponding to a single magnetron sputtering assembly in the target magnetron sputtering assembly 41, which not only helps to control the sputtering rate of the magnetron sputtering mechanism 40, but also helps to improve the uniformity of magnetron sputtering.
[0067] Moreover, to meet the requirements of more diverse deposited films, the first magnetron sputtering assembly 42, the second magnetron sputtering assembly 43, and the third magnetron sputtering assembly 44 can not only be configured with target materials of the same material to increase the efficiency of magnetron sputtering, but also can be respectively configured with target materials of different materials, so that the first magnetron sputtering assembly 42, the second magnetron sputtering assembly 43, and the third magnetron sputtering assembly 44 can be configured to output different target atoms to the target surface of the substrate to be deposited.
[0068] With such a setting, the PECVD-magnetron sputtering co-deposition doping film layer device 100 can dope multiple substances at the same time, so that the PECVD-magnetron sputtering co-deposition doping film layer device 100 has more diverse usage scenarios and meets more requirements.
[0069] In some embodiments, the gas supply mechanism 70 includes a first gas supply component 71. The first gas supply component 71 is provided with at least two first gas supply ports 72, and both the first magnetron sputtering assembly 42 and the second magnetron sputtering assembly 43 correspond to at least one first gas supply port 72. The gas supply mechanism 70 further includes a second gas supply component 73. The second gas supply component 73 is disposed in the chemical vapor deposition mechanism 30. Among them, the second gas supply component 73 is provided with a plurality of second gas supply ports 74. The plurality of second gas supply ports 74 are located inside the chemical vapor deposition mechanism 30 and are spaced apart and annularly arranged around the circumference of the substrate to be deposited.
[0070] In this embodiment, the first gas supply component 71 is not only close to the first magnetron sputtering assembly 42, the second magnetron sputtering assembly 43, and the third magnetron sputtering assembly 44, but also the first gas supply component 71 further includes three first gas supply ports 72 respectively corresponding to the first magnetron sputtering assembly 42, the second magnetron sputtering assembly 43, and the third magnetron sputtering assembly 44. Among them, the horizontal height of the first gas supply port 72 on the first gas supply component 71 is equal to that of the magnetron sputtering mechanism 40.
[0071] For example, during the process of preparing a diamond-like carbon film doped with Ag in the second working mode by the PECVD-magnetron sputtering co-deposition doping film device 100, the magnetron sputtering mechanism 40 and the chemical vapor deposition mechanism 30 need to supply Ar and CH4 respectively. Among them, Ar is introduced into the magnetron sputtering mechanism 40 through the first gas supply port 72 of the first gas supply component 71. Moreover, the distances between the first gas supply port 72 and the first magnetron sputtering component 42, the second magnetron sputtering component 43, and the third magnetron sputtering component 44 are close, which can improve the sputtering efficiency of the magnetron sputtering mechanism. CH4 is introduced into the chemical vapor deposition mechanism 30 through the second gas supply port 74 of the second gas supply component 73. Also, the distance between the second gas supply port 74 and the chemical vapor deposition mechanism 30 is close, which can improve the deposition efficiency of PECVD.
[0072] The first gas supply component 71 and the second gas supply component 73 are respectively arranged corresponding to the adjacent positions of the magnetron sputtering mechanism 40 and the chemical vapor deposition mechanism 30. With such an arrangement, when the gas supply mechanism 70 inputs two working gases into the magnetron sputtering mechanism 40 and the chemical vapor deposition mechanism 30 respectively, it can not only reduce the influence between the two working gases on each other, but also improve the working efficiency of the two mechanisms.
[0073] In some embodiments, the chemical vapor deposition mechanism 30 is disposed around the circumference of the substrate connection component 20, and the substrate connection component 20 can rotate relative to the chemical vapor deposition mechanism 30. During the magnetron sputtering coating process, the rotation of the substrate connection component 20 can make the coating formed by magnetron sputtering on the substrate to be deposited more uniform. Moreover, the substrate connection component 20 is provided with a heating part 21 for increasing the temperature of the substrate to be deposited. The setting of the heating part 21 can not only provide a suitable temperature according to the coating conditions, but also improve the deposition efficiency.
[0074] Among them, the PECVD-magnetron sputtering co-deposition doping film device 100 is further provided with a first driving mechanism 60, and the first driving mechanism 60 is used to drive at least one of the substrate connection component 20 and the chemical vapor deposition mechanism 30 to move, so as to adjust the distance between the substrate connection component 20 and the magnetron sputtering mechanism 40.
[0075] When only the magnetron sputtering mechanism 40 operates for magnetron sputtering in the first working mode, the first driving mechanism 60 can only drive the substrate connection component 20 to move away from or close to the magnetron sputtering mechanism 40. During this process, the substrate connection component 20 and the chemical vapor deposition mechanism 30 move relative to each other.
[0076] When the chemical vapor deposition mechanism 30 and the magnetron sputtering mechanism 40 are operating in the second working mode, the first driving mechanism 60 can drive the substrate connecting member 20 and the chemical vapor deposition mechanism 30 to move away from or closer to the magnetron sputtering mechanism 40 at the same time. During the movement, the distance between the substrate connecting member 20 and the chemical vapor deposition mechanism 30 remains relatively fixed.
[0077] With such a setting, by controlling the adjustment of the distance between the substrate connecting member 20 and the magnetron sputtering mechanism 40, the sputtering rate of magnetron sputtering and the content of target atoms in the coating formed on the substrate to be deposited in the substrate connecting member 20 can be controlled. Moreover, during the operation of PECVD, the relative distance between the substrate connecting member 20 and the chemical vapor deposition mechanism 30 will not be affected.
[0078] Please refer to Figure 4 , Figure 4 which is a schematic three-dimensional structure diagram of a sputtering adjustment mechanism provided by an embodiment of the present application.
[0079] As Figure 4 shown, in some embodiments, the sputtering adjustment mechanism 50 includes a first adjustment component 51 for adjusting the output rate of target atoms. The first adjustment component 51 includes a first baffle 52, a first driving member 53 and a connecting member 55. Among them, the first baffle 52 is rotatably connected to the connecting member 55.
[0080] The first baffle 52 is arranged between the magnetron sputtering mechanism 40 and the substrate connecting member 20, and a plurality of through holes 59 are formed on the first baffle 52. The first driving member 53 is connected to the first baffle 52 and can drive the first baffle 52 to rotate and adjust the rotation speed of the first baffle 52.
[0081] By rotating the first baffle 52 of the sputtering adjustment mechanism 50, the through holes 59 formed on the first baffle 52 can not only allow some target atoms to pass through, but also block the deposition of some atoms. Among them, the rotation speed of the first baffle 52 is negatively correlated with the flow rate of target atoms output by the magnetron sputtering mechanism 40 to the target surface.
[0082] It can be understood that during the operation of the magnetron sputtering mechanism 40, the first driving component 53 drives the first baffle 52 to rotate and adjusts the rotation speed of the first baffle 52. When the rotation speed of the first baffle 52 slows down, the number of atoms passing through the through-hole 59 on the first baffle 52 increases, and the atomic deposition rate on the substrate to be deposited accelerates; when the rotation speed of the first baffle 52 increases, the number of atoms passing through the through-hole 59 on the first baffle 52 decreases, and the atomic deposition rate on the substrate to be deposited slows down. The sputtering adjustment mechanism 50 adjusts the output flow of target atoms by adjusting the rotation speed of the first baffle 52, realizing precise control of the magnetron sputtering deposition rate, and thus can precisely control the content of target atoms in the substrate to be deposited.
[0083] For example, Ag is one of the metals with a high sputtering rate. During the sputtering process of an Ag target, the sputtering rate of its Ag atoms is relatively fast, making it difficult to precisely control the content of the doped element silver in the substrate to be deposited. By arranging the first adjustment component 51 above the Ag target and controlling the rotation speed of the first baffle 52, the number of Ag particles sputtering through the through-hole 59 is controlled, thereby precisely controlling the content of Ag atoms in the substrate to be deposited.
[0084] With such a setting, the sputtering adjustment mechanism 50 can, through the first adjustment component 51, not only control the deposition rate of some materials with a high sputtering rate, thereby precisely controlling the content of high-sputtering-rate particles in the deposited thin film, but also improve the deposition uniformity of the thin film formed by the magnetron sputtering mechanism 40 on the substrate surface. Moreover, the structure of the first adjustment component 51 is simple and practical, improving the maintenance convenience and use stability of the PECVD-magnetron sputtering co-deposition doping film device 100.
[0085] In some embodiments, the first adjustment component 51 further includes a second driving component. The second driving component is connected to one end of the connecting member 55, and the other end of the connecting member 55 is connected to the first baffle 52. Driven by the second driving component, the first baffle 52 can be driven by the connecting member 55 to move relative to the sputtering adjustment mechanism 50, so that the first baffle 52 can approach or move away from the sputtering adjustment mechanism 50.
[0086] It can be understood that in the case where the sputtering adjustment mechanism 50 processes a target with a high sputtering rate, the second driving component can be used to drive the connecting member 55 to drive the first baffle 52 to approach the sputtering adjustment mechanism 50 and stay fixed above the target, and then the first driving component 53 is used to drive the first baffle 52 to rotate, so that the first baffle 52 can control the deposition rate of the target with a high sputtering rate.
[0087] When the sputtering adjustment mechanism 50 processes a target that does not require control of the deposition rate, the second driving component can drive the first baffle 52 away from the sputtering adjustment mechanism 50 through the connecting member 55, so that the target can directly face the substrate to be deposited of the substrate connecting component 20 without obstruction.
[0088] With such a setting, the PECVD-magnetron sputtering co-deposition doping film device 100 can adopt corresponding processing means for targets of different materials, so that the PECVD-magnetron sputtering co-deposition doping film device 100 can cope with more usage scenarios, thereby improving the usage efficiency of the device.
[0089] In some embodiments, a plurality of through holes 59 are arranged at intervals on the first baffle 52. A first gear portion 54 is disposed around the periphery of the first baffle 52. Moreover, the first baffle 52 is engaged with the first driving component 53 through the first gear portion 54, so that the first driving component 53 can drive the first baffle 52 to rotate through the first gear portion 54 and adjust the rotation speed of the first baffle 52.
[0090] By disposing the first gear portion 54 around the periphery of the first baffle 52, during the process of rotating the first baffle 52 to adjust the sputtering rate, the first gear portion 54 and the first driving component 53 will not block the sputtering path passing through the first baffle 52.
[0091] Wherein, there is a first distance L between the first baffle 52 and the magnetron sputtering mechanism 40, and the first distance L is 5 cm.
[0092] With such a setting, in order to make the first baffle 52 almost completely cover the magnetron sputtering mechanism 40, which is beneficial to the control of the deposition rate of sputtered atoms by the first adjustment component 51, while there is a certain distance between the first baffle 52 and the magnetron sputtering mechanism 40, it can ensure that the ionized Ar* can bombard the target below the first baffle 52. Therefore, maintaining a suitable distance between the first baffle 52 and the target of the magnetron sputtering mechanism 40 can ensure the efficiency of Ar* bombarding the target.
[0093] Please refer to Figure 5 and Figure 6 , Figure 5 which is a three-dimensional structural schematic diagram of the second adjustment component provided by the embodiment of the present application in the first position, Figure 6 which is a three-dimensional structural schematic diagram of the second adjustment component provided by the embodiment of the present application in the second position.
[0094] As Figure 5 and Figure 6As shown, in some embodiments, the sputtering adjustment mechanism 50 further includes a second adjustment component 56. The second adjustment component 56 includes a second baffle 57 and a second drive component 58. Among them, the second baffle 57 is disposed between the first adjustment component 51 and the magnetron sputtering mechanism 40, and is in close contact with one end of the magnetron sputtering mechanism 40 where the target is placed.
[0095] The second drive component 58 is connected to the second baffle 57 and is used to drive the second baffle 57 to move, so that the second baffle 57 can rotate relative to the magnetron sputtering mechanism 40 to a first position or a second position. Among them, the region where the magnetron sputtering mechanism 40 outputs target atoms forms a magnetron sputtering surface. When the second baffle 57 rotates to the first position and the second position relative to the magnetron sputtering mechanism 40 respectively, the second baffle 57 forms a first projection and a second projection in the direction perpendicular to the magnetron sputtering surface respectively, and the area of the first projection covering the magnetron sputtering surface is larger than the area of the second projection covering the magnetron sputtering surface.
[0096] It can be understood that when the second baffle 57 rotates to the first position, the second baffle 57 can cover and cover the target of the first magnetron sputtering component 42, so that the first projection overlaps with the target at one end of the first magnetron sputtering component 42.
[0097] When the second baffle 57 rotates to the second position, the second baffle 57 completely exposes the target of the first magnetron sputtering component 42, so that the second projection does not overlap with the target at one end of the first magnetron sputtering component 42.
[0098] For example, when the first magnetron sputtering component 42 needs to perform magnetron sputtering while the second magnetron sputtering component 43 does not need to perform magnetron sputtering, the second baffle 57 of the first magnetron sputtering component 42 rotates to the second position, so that the target of the first magnetron sputtering component 42 is not blocked and is exposed for magnetron sputtering. At the same time, the second baffle 57 of the second magnetron sputtering component 43 rotates to the first position, so that the target of the second magnetron sputtering component 43 is covered and will not be contaminated by the atoms sputtered by the first magnetron sputtering component 42.
[0099] With such a setting, when some magnetron sputtering components in the magnetron sputtering mechanism 40 perform magnetron sputtering, the second adjustment component 56 can prevent the targets of other magnetron sputtering components in the magnetron sputtering mechanism 40 from being contaminated, greatly improving the use experience of the PECVD-magnetron sputtering co-deposition doping film device 100. Moreover, the closer contact of the second baffle 57 can reduce the exposed area of the target of the magnetron sputtering component, thus reducing the possibility of the target being contaminated.
[0100] In some embodiments, the PECVD-magnetron sputtering co-deposited doped film layer device 100 further includes a vacuum mechanism, which can be used to perform a vacuum pumping operation on the accommodation cavity 11 before introducing the reaction gas.
