Technical Field
The invention belongs to the field of semiconductor equipment manufacturing, and particularly relates to a turntable positioning device, a loading and conveying system and plasma processing equipment.
Background
With the continuous development of microelectronic technology, the competition of related production enterprises is more and more intense, and reducing the cost and improving the production efficiency are common means for improving the enterprise competitiveness. For example, in order to improve the production efficiency and reduce the production cost, different processes are simultaneously performed on a plurality of substrates by using a loading and conveying system in the process of performing the process, so as to meet the increasing market demand.
Fig. 1 is a schematic diagram of a conventional load transfer system. FIG. 2A is a top view of the reaction chamber of FIG. 1. Fig. 2B is a sectional view taken along line a-a of fig. 2A. As shown in fig. 1, the load-and-transfer system includes a loading and unloading chamber 1, a transfer chamber 2, and a reaction chamber 3. Wherein the loading and unloading chamber 1 is used for loading or unloading a substrate; the transfer chamber 2 is disposed between the loading and unloading chamber 1 and the reaction chamber 3, and is provided with a robot 21 for transferring substrates between the loading and unloading chamber 1 and the reaction chamber 3.
As shown in fig. 2A and 2B, the reaction chamber 3 includes a turntable 31, a turntable rotating mechanism 35, a target 32, an ejector pin 33, an ejector pin elevating mechanism 36, a susceptor 34, and a susceptor elevating mechanism 37. The main working processes of the reaction chamber 3 are: the turntable rotating mechanism 35 drives the turntable 31 to rotate, so that one of the eight stations rotates to a loading and unloading position (as the position of the station 1 in fig. 1) for loading and unloading the substrate 40; the thimble lifting mechanism 36 drives the thimble 33 which is arranged at the bottom of the turntable 31 and corresponds to the loading and unloading position to lift, so that the top end of the thimble 33 penetrates through the turntable 31 and is higher than the upper surface of the turntable; the manipulator 21 places the substrate 40 on the top end of the thimble 33; the thimble lifting mechanism 36 drives the thimble 33 carrying the substrate 40 to descend until the top end of the thimble 33 is positioned below the turntable 31, and the substrate 40 falls on the station at the loading and unloading position, thereby completing the loading of one substrate; after all the stations are loaded with the substrates 40, the turntable rotating mechanism 35 drives the turntable 31 to rotate, so that four of the eight stations are correspondingly positioned below the four targets 32; the base lifting mechanism 37 drives the four bases 34 which are positioned at the bottom of the turntable 31 and correspond to the targets 32 to ascend, so that the upper surfaces of the bases 34 penetrate through the turntable 31 and support the substrates 40 on the corresponding stations until the substrates reach the bottoms of the through holes 38 which are arranged on the top wall of the chamber and correspond to the targets 32, at the moment, sub-chambers are formed by the targets 32, the through holes 38 and the upper surfaces of the bases 34, and the four sub-chambers are used for simultaneously carrying out different processes on the substrates 40; after the secondary process is completed, the base lifting mechanism 37 drives the base 34 to descend until the upper surface of the base 34 is positioned below the turntable 31, and at this time, the substrate 40 falls on the corresponding station of the turntable 31; the turntable rotating mechanism 35 drives the turntable 31 to rotate, so that each station completing the current process rotates to the position below the target 32 corresponding to the next process; the above steps of "raising the substrate", "processing the substrate", "lowering the substrate", and "rotating the substrate" are repeated until each substrate 40 has completed all the processes.
Before the working process is carried out, the original point search is carried out on the rotary table by means of the rotary table positioning device, so that the rotary table can rotate from the original point position, and the rotary positioning of each station is completed. Fig. 3 is a top view of a conventional turntable positioning device. As shown in fig. 3, the turntable positioning means includes an origin protrusion 41 provided on the outer peripheral wall of the turntable 31, and a laser diffuse reflection sensor 43 provided outside a transparent observation window 42 of the reaction chamber 3. When the laser diffuse reflection sensor 43 detects the origin protrusion 41 at the time of performing the origin search, the motor in the turntable rotating mechanism can be considered to be at the origin position at this time, and then the motor is controlled to perform the absolute movement to drive the turntable 31 to rotate by the specified angle. In addition, the motor in the turntable rotating mechanism usually has a motion controller, which can detect the rotation angle of the motor in real time, so that the rotation angle of the turntable 31 can be known according to the feedback signal provided by the motion controller, and further whether the station of the turntable is in place can be judged.
The turntable positioning device inevitably has the following problems in practical application:
because the turntable positioning device can only perform origin positioning on the turntable, and whether the station of the turntable reaches the preset position can not be monitored in the process, the position abnormity of the station of the turntable can not be timely known, so that the working process can not be continued, mechanical faults can also be caused, and the safety and the stability of the plasma processing equipment are further reduced.
Although the motion controller of the motor can indirectly know the rotation angle of the turntable by detecting the rotation angle of the motor, the rotation angle of the turntable is deviated due to mechanical errors in the rotation mechanism of the turntable and transmission between the rotation mechanism and the turntable, so that the situation that the motor rotates in place but a station of the turntable does not reach the station in the process occurs, or the situation that the angle deviation of the rotation mechanism does not exceed the allowable range and the angle deviation of the edge of the turntable exceeds the allowable range occurs because the angle deviation of the turntable is amplified by the edge of the turntable. When the two conditions occur, the motion controller of the motor still provides a feedback signal indicating that the station of the turntable is in place, so that the judgment on whether the station of the turntable is in place is wrong, mechanical faults can be caused, and the safety and the stability of the plasma processing equipment are reduced.

Whether the station reaches the preset position or not can be judged by detecting the first identification module by means of the first detection module of the in-place detection unit, so that the position abnormality of the station of the turntable can be timely known, the normal operation of the working process can be ensured, mechanical faults can be avoided, and the safety and the stability of the plasma processing equipment can be improved.
Example one
Fig. 4A is a top view of a turntable positioning device according to an embodiment of the present invention. Fig. 4B is a side view of fig. 4A in a direction a. Referring to fig. 4A and 4B, in the present embodiment, a plurality of stations 51 are disposed on the turntable 50, and the stations 51 are spaced along the circumferential direction of the turntable 50.
In the in-place detection unit, the first identification module comprises first convex parts 54, the first convex parts 54 are arranged on the peripheral wall of the turntable 50, and the number and the positions correspond to those of the stations 51 one by one; the first detection module includes a first distance sensor 52 and a first controller (not shown in the drawings), wherein the first distance sensor 52 is disposed at the periphery of the outer circumferential wall of the turntable 50 to emit a detection signal toward a path through which the first protrusion 54 passes when the turntable 50 rotates from its origin position, and to receive a feedback signal from each position on the path, and to transmit the feedback signal to the first controller. In the present embodiment, the number of the first distance sensors 52 is less than or equal to the number of the stations 51, and when the turntable 50 is at the home position, the position of each first distance sensor 52 corresponds to the position of one of all the first protrusions 54, and each first distance sensor 52 corresponds to a different first protrusion 54. For example, in fig. 4A, the number of each of the stations 51 and the first projections 54 is eight; the number of the first distance sensors 52 is one, and when the dial 50 is at the home position, the first distance sensors 52 correspond to the first convex portions 54 located uppermost. The first controller is used for judging whether the feedback signal comes from the first convex part 54 or not when the turntable 50 rotates to a preset angle, and if so, determining that the station reaches a preset position; if not, determining that the position of the station 51 of the turntable is abnormal. The preset angle is an angle that the turntable needs to rotate from the original position when the preset station reaches the preset position. For example, in fig. 4A, if it is set that the first protrusion 54 located at the lowermost position reaches the predetermined position located at the uppermost position of the turntable 50, the turntable 50 needs to rotate 180 ° from the current origin position, at this time, the first controller determines whether the feedback signal is from the first protrusion 54, and if so, it is determined that the station 51 reaches the predetermined position; if not, the position of the station 51 of the turntable is determined to be abnormal.
In the origin detection unit, the second identification module includes a second protrusion 55, and the second protrusion 55 is provided on the outer circumferential wall of the turntable 50 at a position corresponding to the origin position of the turntable 50, as shown in fig. 4A; the second detection module includes a second distance sensor 53 and a second controller (not shown in the figure), wherein the second distance sensor 53 is disposed at the periphery of the outer circumferential wall of the turntable 50, and is configured to emit a detection signal toward a path through which the second protrusion 55 passes when the turntable 50 rotates, and receive a feedback signal from each position on the path, and transmit the feedback signal to the second controller; the second controller is configured to determine whether the feedback signal is from the second protrusion 55, and if so, determine that the turntable 50 reaches the origin position according to the position of the second protrusion 55.
Preferably, the second controller resets the rotation angle of the dial 50 each time it is determined that the dial 50 reaches the origin position, that is, resets the rotation angle of the dial 50 to zero during the rotation of the dial 50 as long as the second controller judges that the feedback signal is from the second protrusion 55. The rotation angle error of the turntable 50 is affected by the radius of the turntable 50, that is, the larger the radius of the turntable 50 is, the larger the rotation angle error of the turntable 50 is, and vice versa, and the rotation angle error of the turntable 50 is increased with the increase of the number of rotation turns of the turntable 50, which finally results in the rotation angle error of the turntable 50 exceeding the allowable safety range, thereby causing inaccurate positioning of the turntable 50. For this reason, by resetting the rotation angle of the dial 50 every time it is determined that the dial 50 reaches the home position by means of the second controller, the rotation angle error generated every rotation of the dial 50 can be cleared, which corresponds to repositioning the home position of the dial 50, so that the rotation angle error of the dial 50 can be controlled within an allowable safety range.
In the present embodiment, the second protrusion 55 and one of the first protrusions 54 are provided at the same position, and both adopt an integrated structure, as shown in fig. 4B, and, in order that the first distance sensor 52 can detect only the first protrusion 54 and the second distance sensor 53 can detect only the second protrusion 55, the first protrusion 54 includes a first extension 541 protruding from the upper surface of the dial 50, and the second protrusion 55 includes a second extension 551 protruding from the lower surface of the dial, and the first distance sensor 52 and the second distance sensor 53 emit detection signals toward paths through which the first extension 541 and the second extension 551 pass, respectively.
Since the first and second extending portions 541 and 551 have a height difference in the vertical direction, this enables the first distance sensor 52 to detect only the path that the first extending portion 541 passes through, and the second distance sensor 53 to detect only the path that the second extending portion 551 passes through, so that it can be ensured that the first and second distance sensors 52 and 53 are not interfered with by the second and first convex portions 55 and 54. In addition, by means of the first extension portion 541 and the second extension portion 551, the detection signals emitted by the first distance sensor 52 and the second distance sensor 53 can be higher or lower than the outer peripheral wall of the turntable 50, so that in the process of performing the in-place detection or the origin detection, the first distance sensor 52 and the second distance sensor 53 receive the feedback signals only when the first extension portion 541 and the second extension portion 551 pass through the first distance sensor 52 and the second distance sensor 53, respectively, which not only improves the detection sensitivity of the first distance sensor 52 and the second distance sensor 53, but also does not require a high requirement on the flatness of the outer peripheral wall of the turntable 50, so that the processing difficulty can be reduced, and the processing cost can be reduced.
Of course, in practical applications, the first protrusion may also include a first extension extending out of the lower surface of the turntable, and the second protrusion includes a second extension extending out of the upper surface of the turntable, and the first distance sensor and the second distance sensor emit the detection signal toward paths through which the first extension and the second extension pass, respectively.
Further, the first extension portion and the second extension portion may be omitted, and the horizontal distance between the detection surface of the first protrusion and the first distance sensor may be made different from the horizontal distance between the detection surface of the second protrusion and the second distance sensor, that is, the lengths of the first protrusion and the second protrusion in the radial direction of the turntable may be made different, so that the first distance sensor and the second distance sensor recognize the first protrusion and the second protrusion from the detected distance.
In the present embodiment, the first detection module and the second detection module are both detected by using a laser reflection type distance sensor, but the present invention is not limited to this, and in practical applications, other types of sensors may be used, and according to the type of the sensor, parameters such as the mounting method of the first detection module and the second detection module, the position and the distance relative to the turntable, and the like may be adjusted accordingly, and parameters such as the structure, the size, the material, and the mounting manner of the first identification module and the second identification module should be adjusted accordingly. As long as the origin detecting unit can detect the origin position of the turntable, and the in-place detecting unit can monitor whether the station of the turntable reaches the preset position.
It should be noted that, in the present embodiment, the number and the positions of the first protruding portions 54 correspond to the number and the positions of the stations 51 one by one, and the number of the first distance sensors 52 is less than or equal to the number of the stations 51, but the present invention is not limited to this, and in practical applications, the following arrangement may also be adopted: as shown in fig. 5A and 5B, the number of the first projections 54 is made smaller than or equal to the number of the stations; when the turntable is at the home position, the number and positions of the first distance sensors 52 correspond to those of the stations 51 one-to-one, and the position of each first protrusion 54 corresponds to the position of one of all the first distance sensors 52, and each first protrusion 54 corresponds to a different first distance sensor 52. For example, in fig. 5A, each of the number of the stations 51 and the first distance sensors 52 is eight; the number of the first convex portions 54 is one, and when the dial 50 is at the origin position, the first convex portions 54 correspond to the first distance sensors 52 located uppermost.
It should be further noted that in the present embodiment, the second protrusion 55 and one of the first protrusions 54 are disposed at the same position, in other words, the origin position of the turntable 50 corresponds to the position of one of the stations 51, but the present invention is not limited thereto, and in practical applications, the origin position of the turntable may be freely set according to specific needs, that is, the position of the second protrusion may be different from the position of the first protrusion, and the two may be independent of each other.
It should be further noted that in the present embodiment, the number of the stations 51 is plural, and the stations are arranged at intervals along the circumferential direction of the turntable 50, but the present invention is not limited to this, and in practical application, the number of the stations may be one, and the stations are arranged at specific positions along the circumferential direction of the turntable according to specific needs. In addition, the first convex part is located at the position corresponding to the station, which means that the first convex part and the station have a preset position relationship, and when the position of the first convex part is determined, the position of the station can be indirectly obtained according to the corresponding relationship. Similarly, the fact that the second convex portion is located at a position corresponding to the origin position of the turntable means that the second convex portion has a preset positional relationship with the origin position of the turntable, and when the position of the second convex portion is determined, the origin position of the turntable can be indirectly obtained from the corresponding relationship.
Example two
Fig. 6A is a top view of a turntable positioning device according to a second embodiment of the present invention. Fig. 6B is a cross-sectional view taken along line a-a in fig. 6A. Referring to fig. 6A and 6B, in the present embodiment, a plurality of stations 51 are disposed on the turntable 50, and the stations 51 are spaced along the circumferential direction of the turntable 50.
In the in-place detection unit, the first identification module comprises first through holes 61 which are arranged on a bearing surface (namely, the surface of the turntable, which is used for bearing the workpiece) of the turntable 50 where the stations 51 are located and penetrate through the thickness of the turntable 50, and the number and the positions of the first through holes 61 correspond to those of the stations 51 one by one; the first detection module comprises a first correlation sensor 63 and a first controller (not shown in the figure), wherein the first correlation sensor 63 comprises an emitting end and a receiving end which are respectively arranged at the upper side and the lower side of the turntable 50, and the emitting end is used for emitting a detection signal towards a path which the first through hole 61 passes through on the bearing surface of the turntable 50 when the turntable 50 rotates from the origin position; the receiving end is configured to receive a detection signal from the transmitting end through the first through hole 63, and send the detection signal to the first controller. It is easily understood that the detection signal emitted from the transmitting terminal may pass through the through-hole and be received by the receiving terminal only in a case where the transmitting terminal, the through-hole, and the receiving terminal are in a straight line in the vertical direction.
In the present embodiment, the number of the first opposite-jet sensors 63 is less than or equal to the number of the stations 51, and when the turntable 50 is at the origin position, the position of the emitting end and the receiving end of each first opposite-jet sensor 63 corresponds to the position of one of all the first through holes 61, and the emitting end and the receiving end of each first opposite-jet sensor 63 correspond to different first through holes 61. For example, in fig. 6A, the number of each of the stations 51 and the first through holes 61 is eight; the number of the first opposite-radiation sensors 63 is one, and the transmitting end and the receiving end of the first opposite-radiation sensors 63 correspond to the first through hole 61 located at the rightmost side of the turntable 50 when the turntable 50 is at the origin position. The first controller is used for judging whether the receiving end receives the detection signal when the turntable 50 rotates to a preset angle, and if so, determining that the station 51 reaches a preset position; if not, determining that the position of the station 51 is abnormal; the predetermined angle is an angle at which the turntable 50 needs to be rotated from its original position when the predetermined station 51 reaches a predetermined position. For example, in fig. 6A, if it is set that the first through hole 61 located at the leftmost side of the turntable 50 reaches the predetermined position located at the rightmost side of the turntable 50, the turntable 50 needs to rotate 180 ° from the current origin position, at this time, the first controller determines whether the receiving end receives the detection signal, and if so, it determines that the station 51 reaches the predetermined position; if not, the position of the station 51 of the turntable is determined to be abnormal.
In the origin detection unit, the second identification module includes a second through hole 60 disposed on the bearing surface of the turntable 50 where the station 51 is located and penetrating through the thickness of the turntable 50, and the second through hole 60 is located at a position corresponding to the origin position of the turntable 50, as shown in fig. 6B; the second detection module comprises a second correlation sensor 62 and a second controller (not shown in the figure), wherein the second correlation sensor 62 comprises an emitting end and a receiving end which are respectively arranged at the upper side and the lower side of the turntable 50, and the emitting end is used for emitting a detection signal towards a path through which the second through hole 60 on the bearing surface of the turntable 50 passes when the turntable 50 rotates; the receiving end is used for receiving a detection signal from the transmitting end, which passes through the second through hole 60, and sending the detection signal to the second controller; the second controller is used for judging whether the receiving end receives the detection signal, and if so, determining that the turntable 50 reaches the original point position.
Preferably, the second controller resets the rotation angle of the dial 50 each time it is determined that the dial 50 reaches the origin position, and the resetting method is similar to that of the first embodiment described above, and since the detailed description has already been given in the first embodiment described above, it is not described here again.
In the present embodiment, in order to enable the first correlation sensor 63 to detect only the first through hole 61 and the second correlation sensor 62 to detect only the second through hole 60, the center distance L1 between the second through hole 60 and the turntable is not equal to the center distance L2 between the first through hole 61 and the turntable 50, as shown in fig. 6B, that is, the paths traveled by the first through hole 61 and the second through hole 60 are respectively located at different radii in the circumferential direction of the turntable 50, which may enable the first correlation sensor 63 to detect only the path traveled by the first through hole 61 and enable the second correlation sensor 62 to detect only the path traveled by the second through hole 60, thereby ensuring that the first correlation sensor 63 and the second correlation sensor 62 are not interfered by the second through hole 60 and the first through hole 61.
It should be noted that, in the present embodiment, the number and the positions of the first through holes 61 correspond to the number and the positions of the stations 51 one by one, and the number of the first correlation sensors 63 is less than or equal to the number of the stations 51, but the present invention is not limited to this, and in practical applications, the following arrangement may also be adopted: the number of first through holes 61 is less than or equal to the number of stations 51; when the turntable 50 is at the home position, the number and positions of the first registration sensors 63 correspond to those of the stations 51 one-to-one, and the position of each first through hole 61 corresponds to the position of one of all the first registration sensors 63, and each first through hole 61 corresponds to a different first registration sensor 63.
