[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0042] Referring to FIG1 , a schematic diagram of the structure of a wafer cutting apparatus 42 is shown. The apparatus includes a cutting tool 46, a height sensor (including a light-emitting portion 56 and a light-receiving portion 58), a tool intrusion portion 54, and cutting fluid 21 for cooling and lubricating the tool and workpiece during the cutting process. The light-emitting portion 56 of the height sensor emits light, while the light-receiving portion 58 receives the light. The height sensor collects the luminous flux from the light-receiving portion 58 and calculates the height of the cutting tool based on the luminous flux. Based on this height information, the wafer cutting apparatus 42 controls the movement of the cutting tool 46 to perform wafer cutting.
[0043] FIG2a shows the relative positional relationship between the cutting tool 46 and the light receiving portion 58 of the height sensor (taking the left view of the wafer cutting device provided in FIG1 as an example). Under ideal conditions, the initial luminous flux of the light receiving portion of the height sensor is 100%, that is, there is no detection object at the current detection position. However, as described in the background technology, there are interference factors such as water vapor from the cutting fluid in the wafer cutting device, and the height sensor is easily splashed by liquid during the previous processing. FIG2b shows that the lower part of the light receiving portion 58 of the height sensor receives the splash of cutting fluid. Therefore, the initial luminous flux of the light receiving portion of the height sensor is only 95% (for example only). Under such interference conditions, the accuracy of the height sensor in measuring the distance between the cutting tool and the stage is greatly affected, thereby affecting the processing accuracy of the wafer cutting device.
[0044] Based on this, an embodiment of the present application provides a method for moving equipment to avoid the problem of insufficient accuracy of equipment movement control caused by the influence of environmental interference factors on the height measuring sensor, thereby ensuring the processing accuracy of the wafer cutting device.
[0045] 3 , which shows a flow chart of a method for moving a device. The method may include:
[0046] Step S100: obtaining a first voltage value collected by a height measuring sensor when the cutting tool is at a first position, where the first position is a position where the cutting tool is not detected by the height measuring sensor.
[0047] Specifically, the wafer cutting device can obtain the first voltage value collected by the height measuring sensor when no processing work is carried out, or can obtain the first voltage value collected by the height measuring sensor when the cutting tool moves downward and is not detected by the height measuring sensor.
[0048] As an optional implementation method, the above-mentioned step S100 may specifically include: obtaining the voltage value collected by the height measuring sensor when the cutting tool is in an initial position, the initial position being the position where the cutting tool is not detected by the height measuring sensor; or, obtaining the voltage value collected by the height measuring sensor when the cutting tool is in a second position, the second position being the position where the total height between the cutting tool and the worktable decreases to a first height at a first speed and is not detected by the height measuring sensor.
[0049] It can be understood that the initial position is the position where the cutting tool stops when the wafer cutting device is not processing wafers, and the second position is the position where the cutting tool moves downward when the wafer cutting device is processing wafers but has not yet been detected by the height sensor. Therefore, the collected first voltage value can be used as the initial voltage value of the height sensor, reflecting the initial parameters of the height sensor in the current operating scenario, facilitating subsequent adjustments to the cutting tool height measurement calculation.
[0050] As an optional implementation, the cutting tool may be a blade or other device with a cutting function.
[0051] As an optional implementation method, the total height can be the distance between the center of the cutting tool and the worktable. The reference point can be the worktable or the center of the cutting tool, and the specific height is further determined by actual conditions.
[0052] As an optional implementation, the movement of the cutting tool or the stage is accomplished by a motor. That is, the controller issues corresponding instructions to control the movement of the cutting tool or the stage. This application does not impose any restrictions on the motor and the controller.
[0053] As an optional implementation, the cutting tool may be moved while the stage remains fixed. Specifically, the cutting tool moves a first distance toward the stage at a first speed to a first height, where the first height is determined based on the total height and the loss value of the cutting tool.
[0054] As an optional implementation, the stage may move while the cutting tool remains fixed. Specifically, the stage moves a first distance toward the cutting tool at a first speed to a first height, where the first height is determined based on the total height and the loss value of the cutting tool.
[0055] Through the above two optional implementation methods, either the stage or the cutting tool can be moved. Therefore, during the equipment installation process, the appropriate method can be selected according to the actual situation on site, which can effectively improve the flexibility of equipment installation.
[0056] As an optional implementation, the first height is determined based on the total height and the loss value of the cutting tool. The loss value of the cutting tool can be 0.1 mm, which is an estimated value based on a large amount of data statistics, that is, it is estimated that the loss value of the cutting tool is 0.1 mm for each cutting action.
[0057] It should be noted that the wafer cutting process is a multi-cycle process, that is, each time the cutting equipment is started, multiple cuts are completed. Therefore, the total height is also a constantly changing value. The current total height is the relative height between the cutting tool center and the stage after the last cut was completed.
[0058] Step S200: determining a target threshold voltage of the height measuring sensor according to the first voltage value.
[0059] Specifically, a target preset voltage for controlling the cutting tool to stop movement is determined based on the first voltage value. It is understood that because the first voltage value is the initial voltage value of the altimeter sensor, it reflects the initial parameters of the altimeter sensor in the current operating scenario. This makes subsequent cutting tool height measurement calculations more accurate, ensuring accurate control of the cutting tool.
[0060] As an optional implementation, the above step S200 may specifically include the following steps:
[0061] Step S201: determining a corrected voltage value of the altimeter sensor according to the first voltage value, wherein the corrected voltage value is a voltage value generated when the altimeter sensor is affected by an obstructing object.
[0062] Step S202: determining a target threshold voltage of the height sensor based on the correction voltage value and the cutting height requirement.
[0063] Specifically, the correction voltage value is the voltage value generated when the height measuring sensor is affected by obstructing objects such as water vapor, cutting fluid splashing, etc. The target threshold voltage is calculated based on the correction voltage value and the cutting height requirement, where the cutting height requirement can be set according to actual processing requirements.
[0064] Step S300: In response to the height measuring sensor collecting the target threshold voltage, the cutting tool is controlled to stop moving downward.
[0065] Specifically, when the height measuring sensor detects the target threshold voltage, the cutting tool is controlled to stop moving downward.
[0066] As an optional implementation method, the above step S300 may specifically include: reducing the height between the cutting tool and the worktable at a second speed until the height sensor collects the target threshold voltage, and controlling the cutting tool to stop moving downward, wherein the first speed is not equal to the second speed.
[0067] As an optional implementation, the first speed is greater than the second speed.
[0068] It can be understood that the second speed is lower than the first speed, which can ensure that the cutting tool approaches the stage at a relatively slow speed to cut the wafer, thereby ensuring the safety of the processing and the equipment.
[0069] The above method determines the target threshold voltage based on the first voltage value collected when the height sensor fails to detect the cutting tool, and controls the cutting tool to stop moving based on the target threshold voltage. As a result, the wafer cutting apparatus can reset the voltage threshold based on the pre-processing luminous flux of the light sensor, thereby reducing interference with the height sensor from factors such as moisture, thereby increasing height measurement accuracy and ensuring wafer processing precision.
[0070] As an optional implementation, after the above-mentioned step S300, the method provided in the embodiment of the present application also includes step S400: moving the cutting tool and the worktable away from each other at a third speed until the cutting tool and the worktable are at a second height, wherein the third speed is less than the first speed, and the second height is less than the first height; reducing the second height between the cutting tool and the worktable at a fourth speed until the height sensor collects the target threshold voltage and controls the cutting tool to stop moving downward.
[0071] Since the wafer cutting process is a multi-cycle process and multiple cutting processes need to be completed, after controlling the cutting tool to stop moving downward in step S300, it is also necessary to control the cutting tool to move upward and lift up for the second cutting process, and repeat this process to complete multiple cutting processes.
[0072] As an optional implementation, the fourth speed may be equal to the second speed.
[0073] As an optional implementation, before reducing the second height between the cutting tool and the worktable at a fourth speed, the target threshold voltage of the height sensor is re-determined, wherein the second height corresponds to a position where the cutting tool is not detected by the height sensor.
[0074] It is understandable that the obstruction of the height sensor may change as the machining process progresses. To ensure the timeliness of the target threshold voltage, the target threshold voltage of the height sensor is re-determined before each downward movement of the cutting tool, and the movement of the cutting tool is controlled based on the re-determined target threshold voltage. Of course, the re-determined target threshold voltage requires that the second height of the cutting tool's upward movement must satisfy the requirement that the position after the movement is not detected by the height sensor. The method for re-determining the target threshold voltage can be similar to the method for determining the target threshold voltage for the first time, and will not be repeated here.
[0075] In summary, the embodiments of the present application provide a method for moving a device. First, a first voltage value collected by a height sensor when the cutting tool is in a first position is obtained, where the first position is a position where the cutting tool is not detected by the height sensor. Then, a target threshold voltage of the height sensor is determined based on the first voltage value. Finally, in response to the height sensor collecting the target threshold voltage, the cutting tool is controlled to stop moving downward. It can be seen that the embodiments of the present application determine the target threshold voltage for controlling the cutting tool to stop by using the voltage value of the height sensor when the cutting tool is not detected. This can avoid the problem of insufficient accuracy in controlling the movement of the device caused by the influence of environmental interference factors on the height sensor, thereby ensuring the processing accuracy of the wafer cutting device.
