Description

Technical Field

[0001] This invention relates to the field of semiconductor technology, and in particular to a chip marking device. Background Technology

[0002] During chip manufacturing and testing, it is usually necessary to mark the chips that have completed testing to distinguish them from those that have not been tested. Traditional methods of marking chips include laser marking and mechanical dot marking.

[0003] However, traditional marking methods such as mechanical dotting mechanisms are prone to chip misalignment during the chip marking process.

[0004] The information disclosed above in the background art of this application is only used to understand the background of the concept of this application, and may contain information that does not constitute prior art. Summary of the Invention

[0005] Therefore, it is necessary to provide a chip marking device to address the above problems.

[0006] A chip marking device, comprising:

[0007] support;

[0008] A drive assembly, wherein the drive assembly is disposed on the bracket;

[0009] An elastic component, the elastic component being connected to the drive component; and

[0010] A marking component is connected to the driving component. The marking component and the elastic component can move up and down relative to the bracket under the drive of the driving component to contact or separate from the chip. When the marking component contacts the chip, the marking component can mark the chip. The elastic component elastically abuts against the chip, and the elastic component can separate from the chip after the marking component separates from the chip.

[0011] The aforementioned chip marking device can achieve at least the following beneficial effects:

[0012] The driving component moves the marking component and the elastic component up and down relative to the support, so that the marking component completes the marking operation when it contacts the chip, while the elastic component elastically abuts against the chip. The elastic component separates from the chip only after the marking component separates from the chip. That is, the elastic component can delay separation from the chip after marking. When the marking component just separates from the chip, the elastic component still elastically abuts against the chip, ensuring that the marking component can stably detach from the chip surface after marking is completed. This avoids chip adhesion or chip displacement when the marking component retracts, thereby improving the stability and reliability of the chip marking process.

[0013] In some embodiments, the elastic component includes an elastic element and an abutment. One end of the elastic element is connected to the driving component, and the other end is connected to the abutment, which abuts against the chip. The connection of one end of the elastic element to the driving component and the other end to the abutment allows the abutment to directly contact and elastically abut against the chip. This structural design ensures that the elastic component maintains elastic pressure on the chip even after the marking component has completed marking, guaranteeing that the abutment remains stably abutting the chip when the marking component separates from it. This prevents the chip from being lifted or shifted due to the direct retraction of the marking component. Simultaneously, the elastic deformation capability of the elastic element buffers the impact of the driving component's movement, making the contact and separation process between the abutment and the chip smoother, reducing the risk of chip damage, and improving the stability and reliability of chip marking.

[0014] In some embodiments, the driving assembly includes a driving member, a telescopic rod, and a transmission member disposed on the bracket. One end of the telescopic rod is connected to the driving member, and the other end is connected to the transmission member. The transmission member is connected to the marking assembly. One end of the elastic member is connected to the transmission member, and the other end is connected to the abutment member. The connection between the telescopic rod and the driving member, and the transmission member and the marking assembly, and the connection between the elastic member and the transmission member, allows the driving member to precisely control the lifting and lowering movement of the marking assembly via the telescopic rod and transmission member. Simultaneously, the connection between the elastic member and the transmission member ensures that the elastic member moves synchronously with the marking assembly. When the marking assembly contacts the chip, the elastic member provides stable elastic pressure through the abutment member and maintains delayed separation when the marking assembly retracts, thereby effectively preventing chip displacement or adhesion of the marking material and improving the stability and reliability of the marking process.

[0015] In some embodiments, the elastic component further includes a guide post, with a first end connected to the abutment member and a second end retractably extending through the transmission member. By adding a guide post to the elastic component and connecting its first end to the abutment member, and its second end retractably extending through the transmission member, the abutment member can move stably along the axial direction of the guide post under the elastic action of the elastic component. This prevents the abutment member from deflecting or wobbling when abutting the chip. Simultaneously, the retractable design of the guide post ensures that the elastic component can freely compress and rebound, maintaining stable contact between the abutment member and the chip, thereby further improving the positioning accuracy and stability during the chip marking process.

[0016] In some embodiments, a groove is formed on the outer peripheral surface of the second end of the guide post, and the elastic component further includes a retaining spring, which is engaged in the groove to limit the axial movement of the guide post. By forming a groove and providing a retaining spring on the outer peripheral surface of the second end of the guide post, the axial movement of the guide post is limited by the cooperation between the retaining spring and the groove. The limiting effect of the retaining spring prevents the guide post from disengaging from the transmission component, thereby precisely controlling the movement range of the abutment member connected to the guide post and ensuring that the abutment member always provides a stable and appropriate elastic abutment force during the marking process.

[0017] In some embodiments, the elastic element is sleeved on the guide post and elastically abuts against the transmission member and the abutment member. By sleeved on the guide post and elastically abutting against the transmission member and the abutment member, the compression and rebound of the elastic element always occur along the axial direction of the guide post, preventing the elastic element from deflecting or twisting under force, thereby ensuring that the abutment member can apply pressure stably and evenly during the marking process. Simultaneously, this structural design simplifies the assembly process, improves the compactness and reliability of the components, and makes the elastic force transmission of the elastic element more direct and effective, further enhancing the accuracy and stability of chip marking.

[0018] In some embodiments, the marking assembly includes a slider connected to the transmission member and a dotting needle connected to the slider. The abutment member has a clearance hole, which allows the dotting needle to pass through when it contacts the chip. By providing a slider and dotting needle connected to the transmission member and a clearance hole on the abutment member, the dotting needle can pass through the clearance hole and directly contact the chip surface when marking the chip, ensuring precise alignment of the marking position. Simultaneously, the abutment member maintains contact with the chip through a stable abutment force provided by an elastic component, preventing inaccurate marking due to vibration or displacement of the dotting needle during the marking process. This structural design ensures marking accuracy and avoids interference between the abutment member and the dotting needle through the clearance hole, improving the reliability and consistency of the marking process.

[0019] In some embodiments, the driving assembly further includes a limiting post disposed on the transmission member, and a limiting groove is formed on the bracket. At least one end of the limiting post is slidably disposed within the limiting groove. By providing a limiting post on the transmission member and forming a corresponding limiting groove on the bracket, the limiting post can precisely guide the movement trajectory of the transmission member when sliding within the groove, preventing the transmission member from deviating or rotating during driving and ensuring that the movement direction of the marking assembly is stable and controllable. Simultaneously, the limiting groove constrains the sliding range of the limiting post, preventing the transmission member from exceeding the preset stroke, thereby ensuring that the marking action of the dotting needle always occurs within the set range, preventing excessive movement of the dotting needle from damaging the chip, and improving marking accuracy and equipment reliability.

[0020] In some embodiments, the number of limiting posts is set to multiple, with each limiting post corresponding to at least one limiting groove. By setting multiple limiting posts, each corresponding to at least one limiting groove, the motion stability of the transmission component can be further optimized. The synergistic effect of multiple limiting posts can effectively disperse the force during motion, reduce stress concentration at single points, and lower the risk of wear. At the same time, the cooperation between multiple limiting posts and limiting grooves can enhance the torsional resistance of the transmission component, ensuring that it always maintains linear motion during movement.

[0021] In some embodiments, the bracket is further provided with a guide groove, and the chip marking device further includes a rotation fulcrum provided on the bracket. The rotation fulcrum extends along the length of the guide groove and is located in the middle of the guide groove, and the rotation fulcrum is located outside the guide groove. The slider is connected to the rotation fulcrum and can rotate around the rotation fulcrum. The marking assembly also includes a rotating shaft, which is provided on the slider and at least one end of the rotating shaft is slidably disposed in the guide groove. The transmission member is provided with a limiting slot, which is engaged on the outer circumferential surface of the rotating shaft. When the transmission member performs telescopic movement under the drive of the telescopic rod, the transmission member can drive the rotating shaft to slide in the guide groove through the limiting slot and cause the slider to rotate around the rotation fulcrum, so as to drive the dotting needle to flip to a first position or a second position. In the first position, the dotting needle contacts the chip. The rotating shaft is slidably disposed within the guide groove and linked to the transmission component via the limiting latch, forming a compact and efficient transmission structure. The limiting latch is engaged with the outer circumference of the rotating shaft, allowing the extension and retraction of the transmission component to drive the rotating shaft to slide along the guide groove, thereby causing the slider to rotate around the pivot point, realizing the flipping switching of the dotting needle between the first position and the second position. The pivot point is located outside the guide groove and at the center along its length, giving the slider's rotational movement symmetry and stability. The sliding cooperation between the guide groove and the rotating shaft ensures the accuracy of the slider's trajectory when rotating around the pivot point.

[0022] In some embodiments, the rotation fulcrum includes a support shaft and a bearing mounted on the bracket. The inner ring of the bearing is connected to the support shaft. The slider has a rotation groove, and the slider is engaged with the outer ring of the bearing through the rotation groove and can rotate around the support shaft. The connection between the support shaft and the inner ring of the bearing forms a stable center of rotation. The engagement of the outer ring of the bearing with the rotation groove of the slider allows the slider to rotate around the support shaft with low friction. The introduction of the bearing significantly reduces the motion resistance of the slider during rotation, improving the sensitivity and response speed of the dotting needle position switching. The structural design of the rotation groove being engaged with the outer ring of the bearing ensures a reliable connection between the slider and the bearing, while allowing the slider to maintain stable radial positioning during rotation, avoiding wobbling or offset due to gaps. The support shaft, fixed to the bracket, provides rigid support for the entire rotating mechanism, enabling the slider to maintain rotational accuracy when bearing the working load of the dotting needle, ensuring the positioning accuracy and repeatability of the dotting needle when switching between the first and second positions.

[0023] In some embodiments, the chip marking device further includes a material box disposed on the support. In the second position, the dotting needle is separated from the chip and extends into the material box to pick up ink. By setting the material box on the support, the dotting needle can automatically separate from the chip and extend into the material box to pick up ink when it is in the second position. This achieves automatic ink replenishment during the marking process, ensuring that the dotting needle carries sufficient ink each time it marks, thus guaranteeing the clarity and consistency of the marking.

Detailed Implementation

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In some embodiments, this application provides a chip marking device 10, which includes a support 100, a driving component 200, an elastic component 300, and a marking component 400. The driving component 200 is disposed on the support 100, the elastic component 300 is connected to the driving component 200, and the marking component 400 is connected to the driving component 200. The marking component 400 and the elastic component 300 can move up and down relative to the support 100 under the drive of the driving component 200 to contact or separate from the chip 700. When the marking component 400 contacts the chip 700, the marking component 400 can mark the chip 700. The elastic component 300 elastically abuts against the chip 700, and the elastic component 300 can separate from the chip 700 after the marking component 400 separates from the chip 700.

[0035] The chip marking device 10 described above can achieve at least the following beneficial effects:

[0036] The driving component 200 drives the marking component 400 and the elastic component 300 to move up and down relative to the support 100. This allows the marking component 400 to complete the marking operation when it comes into contact with the chip 700, while the elastic component 300 elastically abuts against the chip 700. The elastic component 300 separates from the chip 700 only after the marking component 400 separates from the chip 700. In other words, the elastic component 300 can delay separating from the chip 700 after marking. When the marking component 400 just separates from the chip 700, the elastic component 300 still elastically abuts against the chip 700, ensuring that the marking component 400 can stably detach from the surface of the chip 700 after marking is completed. This avoids the chip 700 from sticking or shifting when the marking component 400 retracts, thereby improving the stability and reliability of the chip 700 marking process.

[0037] like Figure 6 As shown, in some embodiments, the elastic component 300 includes an elastic element 310 and an abutment 320. One end of the elastic element 310 is connected to the driving component 200, and the other end of the elastic element 310 is connected to the abutment 320, which is used to abut against the chip 700. One end of the elastic element 310 is connected to the driving component 200, and the other end is connected to the abutment element 320, allowing the abutment element 320 to directly contact and elastically abut against the chip 700. This structural design ensures that the elastic element 300 maintains elastic pressure on the chip 700 after the marking component 400 completes marking, ensuring that the abutment element 320 can still stably abut against the chip 700 when the marking component 400 separates from the chip 700. This prevents the chip 700 from being lifted or shifted due to the direct retraction of the marking component 400. At the same time, the elastic deformation capability of the elastic element 310 can buffer the movement impact of the driving component 200, making the contact and separation process between the abutment element 320 and the chip 700 smoother, reducing the risk of damaging the chip 700, and improving the stability and reliability of the marking of the chip 700.

[0038] like Figure 1As shown, in some embodiments, the drive assembly 200 includes a drive member 210, a telescopic rod 220, and a transmission member 230 disposed on the bracket 100. One end of the telescopic rod 220 is connected to the drive member 210, and the other end of the telescopic rod 220 is connected to the transmission member 230. The transmission member 230 is connected to the marking assembly 400. One end of the elastic member 310 is connected to the transmission member 230, and the other end of the elastic member 310 is connected to the abutment member 320. The driving component 210 may include, but is not limited to, a cylinder, an electric push rod, etc. One end of the telescopic rod 220 is connected to the driving component 210, and the other end is connected to the transmission component 230. The transmission component 230 is then connected to the marking component 400. At the same time, one end of the elastic component 310 is connected to the transmission component 230, and the other end is connected to the abutment component 320. This structural design allows the driving component 210 to precisely control the lifting and lowering movement of the marking component 400 through the telescopic rod 220 and the transmission component 230. Meanwhile, the connection between the elastic component 310 and the transmission component 230 ensures that the elastic component 300 can move synchronously with the marking component 400. When the marking component 400 contacts the chip 700, the elastic component 310 provides stable elastic pressure through the abutment component 320 and maintains delayed separation when the marking component 400 retracts, thereby effectively preventing the chip 700 from shifting or the marking material from sticking together, and improving the stability and reliability of the marking process.

[0039] like Figure 6 As shown, in some embodiments, the elastic component 300 further includes a guide post 330. The first end of the guide post 330 is connected to the abutment member 320, and the second end of the guide post 330 is retractably inserted through the transmission member 230. By adding a guide post 330 to the elastic component 300, connecting the first end of the guide post 330 to the abutment member 320, and retractably inserting the second end through the transmission member 230, the abutment member 320 can move stably along the axial direction of the guide post 330 under the elastic action of the elastic component 310. This prevents the abutment member 320 from deflecting or wobbling when abutting the chip 700. Simultaneously, the retractable design of the guide post 330 ensures that the elastic component 310 can freely compress and rebound, maintaining stable contact between the abutment member 320 and the chip 700, thereby further improving the positioning accuracy and stability during the marking process of the chip 700.

[0040] like Figure 6As shown, in some embodiments, a groove 331 is formed on the outer peripheral surface of the second end of the guide post 330, and the elastic component 300 further includes a retaining spring 340, which is engaged in the groove 331 to limit the axial movement of the guide post 330. By forming a groove 331 and providing a retaining spring 340 on the outer peripheral surface of the second end of the guide post 330, the axial movement of the guide post 330 is limited by the cooperation between the retaining spring 340 and the groove 331. The limiting effect of the retaining spring 340 can prevent the guide post 330 from disengaging from the transmission component 230, thereby precisely controlling the movement range of the abutment 320 connected to the guide post 330, and ensuring that the abutment 320 always provides a stable and appropriate elastic abutment force during the marking process.

[0041] like Figure 6 As shown, in some embodiments, the elastic element 310 is sleeved on the guide post 330 and elastically abuts against the transmission member 230 and the abutment member 320. By sleeved on the guide post 330 and elastically abutting against the transmission member 230 and the abutment member 320, the compression and rebound of the elastic element 310 always occur along the axial direction of the guide post 330, preventing the elastic element 310 from deflecting or twisting under force, thereby ensuring that the abutment member 320 can apply pressure stably and evenly during the marking process. At the same time, this structural design simplifies the assembly process, improves the compactness and reliability of the components, and makes the elastic force transmission of the elastic element 310 more direct and effective, further enhancing the accuracy and stability of the chip 700 marking.

[0042] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the marking assembly 400 includes a slider 410 connected to the transmission member 230 and a dotting needle 420 connected to the slider 410. The abutment member 320 has a clearance hole 321, which allows the dotting needle 420 to pass through when it contacts the chip 700. By providing the slider 410 and dotting needle 420 connected to the transmission member 230, and the clearance hole 321 on the abutment member 320, the dotting needle 420 can pass through the clearance hole 321 and directly contact the surface of the chip 700 when marking it, ensuring precise alignment of the marking position. Simultaneously, the abutment member 320 maintains contact with the chip 700 through the stable abutting force provided by the elastic component 300, preventing inaccurate marking due to vibration or displacement of the dotting needle 420 during the marking process. This structural design ensures the accuracy of the marking while avoiding interference between the contact part 320 and the dotting needle 420 through the clearance hole 321, thereby improving the reliability and consistency of the marking process.

[0043] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the drive assembly 200 further includes a limiting post 240, which is disposed on the transmission member 230. A limiting groove 110 is formed on the bracket 100, and at least one end of the limiting post 240 is slidably disposed within the limiting groove 110. By providing the limiting post 240 on the transmission member 230 and forming a corresponding limiting groove 110 on the bracket 100, the limiting post 240 can precisely guide the movement trajectory of the transmission member 230 when sliding within the groove, preventing the transmission member 230 from deviating or rotating during the drive process, and ensuring that the movement direction of the marking assembly 400 is stable and controllable. Simultaneously, the limiting groove 110 constrains the sliding range of the limiting post 240, preventing the transmission member 230 from exceeding the preset stroke, thereby ensuring that the marking action of the dotting needle 420 is always within the set range, preventing excessive movement of the dotting needle 420 and damage to the chip 700, and also improving marking accuracy and equipment reliability.

[0044] In some embodiments, the number of limiting posts 240 is set to multiple, and each limiting post 240 corresponds to at least one limiting groove 110. By setting multiple limiting posts 240 and having each correspond to at least one limiting groove 110, the motion stability of the transmission component 230 can be further optimized. The synergistic effect of multiple limiting posts 240 can effectively disperse the force during the motion process, reduce stress concentration at single points, and reduce the risk of wear. At the same time, the cooperation between multiple limiting posts 240 and limiting grooves 110 can enhance the torsional resistance of the transmission component 230, ensuring that it always maintains linear motion during the motion process.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the bracket 100 is further provided with a guide groove 120, and the chip marking device 10 further includes a rotation fulcrum 500 disposed on the bracket 100. The rotation fulcrum 500 is located at the middle of the guide groove 120 along the length direction of the guide groove 120, and the rotation fulcrum 500 is located outside the guide groove 120. The slider 410 is connected to the rotation fulcrum 500 and can rotate around the rotation fulcrum 500. The marking assembly 400 further includes a rotating shaft 430, the rotating shaft 430 is disposed on the slider 410, and at least one of the rotating shaft 430 is located on the slider 410. The end is slidably disposed in the guide groove 120. The transmission member 230 is provided with a limiting slot 231. The limiting slot 231 is engaged with the outer peripheral surface of the rotating shaft 430. When the transmission member 230 moves in extension and retraction under the drive of the telescopic rod 220, the transmission member 230 can drive the rotating shaft 430 to slide in the guide groove 120 through the limiting slot 231, and cause the slider 410 to rotate around the rotation fulcrum 500, so as to drive the dotting needle 420 to flip to the first position or the second position. In the first position, the dotting needle 420 contacts the chip 700. The rotating shaft 430 is slidably disposed within the guide groove 120 and linked with the transmission component 230 through the limiting slot 231, forming a compact and efficient transmission structure. The limiting slot 231 is engaged with the outer circumferential surface of the rotating shaft 430, allowing the extension and retraction movement of the transmission component 230 to drive the rotating shaft 430 to slide along the guide groove 120, thereby causing the slider 410 to rotate around the rotation fulcrum 500, realizing the flipping switching of the dotting needle 420 between the first position and the second position. The rotation fulcrum 500 is located outside the guide groove 120 and at the middle along its length direction, giving the rotational movement of the slider 410 symmetry and stability. The sliding cooperation between the guide groove 120 and the rotating shaft 430 ensures the accuracy of the movement trajectory of the slider 410 when rotating around the rotation fulcrum 500.

[0046] like Figure 1 and Figure 5As shown, in some embodiments, the rotation fulcrum 500 includes a support shaft 510 and a bearing 520 disposed on the bracket 100. The inner ring of the bearing 520 is connected to the support shaft 510. The slider 410 is provided with a rotation groove 411. The slider 410 is engaged with the outer ring of the bearing 520 through the rotation groove 411 and can rotate around the support shaft 510. The support shaft 510 and the inner ring of the bearing 520 form a stable rotation center. The outer ring of the bearing 520 cooperates with the rotation groove 411 of the slider 410, enabling the slider 410 to rotate around the support shaft 510 with low friction. The introduction of the bearing 520 significantly reduces the motion resistance of the slider 410 during rotation, improving the sensitivity and response speed of the dotting needle 420 position switching. The structural design of the rotation groove 411 being engaged with the outer ring of the bearing 520 ensures a reliable connection between the slider 410 and the bearing 520, while allowing the slider 410 to maintain stable radial positioning during rotation, avoiding wobbling or offset caused by gaps. The support shaft 510 is fixed to the bracket 100, providing rigid support for the entire rotating mechanism, enabling the slider 410 to maintain rotational accuracy when bearing the working load of the dotting needle 420, ensuring the positioning accuracy and repeatability of the dotting needle 420 when switching between the first position and the second position.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the chip marking device 10 further includes a material box 600 disposed on the support 100. In the second position, the dotting needle 420 is separated from the chip 700, and the dotting needle 420 extends into the material box 600 to pick up pigment. By setting the material box 600 on the support 100, when the dotting needle 420 is in the second position, it can automatically separate from the chip 700 and extend into the material box 600 to pick up pigment, realizing automatic pigment replenishment during the marking process. This ensures that the dotting needle 420 carries sufficient pigment each time it marks, guaranteeing the clarity and consistency of the marking.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

[0050] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0053] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0054] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0055] In the description of this specification, references to terms such as "an embodiment," "another implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative descriptions of the above terms do not necessarily refer to the same embodiment or example. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
