Description

Seismic processing method, seismic processing device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of crystal preparation, and in particular, to a seismic processing method, a seismic processing apparatus, an electronic device, and a storage medium.

Background

The preparation process of the monocrystalline silicon material mainly comprises a Czochralski method (Czochralski process/CZ), and the polycrystalline silicon raw material is refined into monocrystalline silicon by the Czochralski method. The process of generating rod-shaped monocrystalline silicon crystals in the process of pulling up the monocrystalline comprises the steps of charging, heating and melting, temperature adjustment, seeding, shouldering, shoulder turning, constant diameter ending and the like.

When the polysilicon raw material is melted, seeding cannot be started immediately, and the temperature is higher than the seeding temperature, and the temperature must be adjusted to the seeding temperature through cooling. Seeding is a process in which a seed crystal (i.e., a shaped single crystal) previously loaded onto the end of a wire rope is brought into contact with a liquid surface, and silicon molecules are grown in the lattice direction of the seed crystal at a seeding temperature, thereby forming a single crystal. The shouldering is to gradually grow the crystal diameter to a required diameter, and a section of crystal with the diameter gradually becoming larger to the required diameter or so is pulled out along with the length gradually becoming longer in the shouldering process so as to eliminate crystal dislocation. After the crystal grows to the diameter required by production in the shouldering process, the crystal enters the shouldering process. The shoulder is to control the crystal diameter to the diameter required for production. And after the shoulder turning is finished, the step of equal diameter control is carried out, and in the step, the crystal is grown according to the set diameter equal diameter through automatic control of the pulling speed and the temperature. After the isodiametric growth is completed, the crystal enters a final process which is also used for eliminating dislocation. After finishing, the crystal growth is basically finished, and the crystal is kept in the silicon single crystal furnace for a certain time, so that the annealing of the crystal is finished.

Because of the numerous single crystal furnace tops, when earthquake events occur, the impact on all furnace tops is extremely huge, and the loss caused is extremely huge, especially in the process of gradually forming or extracting the crystal bar in the crystal pulling stage, serious people can cause personal injury besides equipment damage. The first thing to do when an earthquake occurs is to evacuate the personnel on site, and the second thing is to do the operation related to the furnace platform to stop the damage in time, but there is a great hysteresis.

Detailed Description

In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.

Referring to fig. 1, a flowchart illustrating steps of an embodiment of a seismic processing method according to the present invention may specifically include the following steps:

step 101, detecting crystal arcing conditions of a plurality of Czochralski crystal growing apparatuses.

In the embodiment of the present invention, the Czochralski process is a process of pulling a raw material into a single crystal using a Czochralski method, for example, a process of Czochralski silicon. The process of pulling up single crystals can be divided into a charging stage, a melting stage, a temperature adjusting stage, a seeding stage and the like.

In an embodiment of the present invention, the Czochralski crystal apparatus is an apparatus for Czochralski single crystal, such as a single crystal furnace for Czochralski single crystal silicon. The crystal arcing refers to the phenomenon of crystal swing in the process of pulling a single crystal, is an abnormal phenomenon frequently occurring in the process of pulling the single crystal, influences the normal growth of the single crystal, and causes the increase of the production cost of the single crystal, and from the aspect of a growth mechanism, the crystal swing can cause the change of the liquid level temperature, and the stability of a solid-liquid interface is disturbed, so that the quality of the single crystal and the dislocation-free growth are influenced. In terms of operational control, the crystal oscillation can make diameter control difficult and also not conducive to automatic control during isodiametric growth, resulting in a relatively prolonged production cycle and thus increased production costs.

For a large scale production unit, the number of Czochralski single crystal apparatus is relatively large, and the occurrence of crystal arcing of individual Czochralski single crystal apparatus is normal, but is relatively abnormal if a large number of Czochralski single crystal apparatus are involved, and is most likely to be caused by an earthquake.

In the embodiment of the present invention, the detection of the crystal arcing condition of a single czochralski single crystal apparatus may detect the position of the ingot by using a CCD (Charge Coupled Device ) machine vision system, and if the position of the ingot swings and the swing amplitude exceeds a set threshold, determine that the crystal arcing condition of the czochralski single crystal apparatus occurs, or any other suitable implementation manner, and the embodiment of the present invention is not limited thereto. The crystal arcing condition may be divided into two conditions, i.e. a condition in which crystal arcing occurs and a condition in which crystal arcing does not occur, or the condition in which crystal arcing is seen may be subdivided into various degrees of arcing, or any other suitable condition, which is not limited in the embodiments of the present invention.

In the embodiment of the invention, a plurality of Czochralski single crystal devices are detected respectively to obtain the crystal arcing condition of the plurality of Czochralski single crystal devices. For example, each Czochralski single crystal apparatus detects a crystal arcing condition, and reports the crystal arcing condition to the emergency central control platform, from which the earthquake is detected.

And 102, determining a seismic event according to the crystal arc striking conditions of the plurality of Czochralski crystal growing devices.

In the embodiment of the present invention, the seismic event refers to an event in which an earthquake occurs, and the seismic event may be further divided into a slight seismic event, a severe seismic event, etc., or any other suitable seismic event, which is not limited in the embodiment of the present invention.

In the embodiment of the invention, if a certain number of devices in the plurality of Czochralski single crystal devices are likely to be caused by an earthquake, whether the earthquake occurs or not can be reliably determined or the severity of the earthquake can also be determined according to the crystal arcing condition of the plurality of Czochralski single crystal devices.

In the embodiment of the invention, the specific implementation manner for determining the seismic event can comprise a plurality of types according to the crystal arc-striking conditions of the plurality of czochralski crystal devices. For example, a device duty ratio of a single crystal pulling device in which crystal arcing occurs simultaneously in the single crystal pulling device in an isodiametric state is determined from crystal arcing conditions of a plurality of single crystal pulling devices, and a seismic event is determined from the device duty ratio. For another example, the device duty ratio of the Czochralski single crystal device in which crystal arcing occurs simultaneously in the Czochralski single crystal device in the isodiametric state is determined based on the crystal arcing conditions of the plurality of Czochralski single crystal devices, the crystal arcing conditions further including data relating to the crystal arcing, e.g., data describing the extent of the crystal arcing, etc., and the seismic event is determined in combination with the device duty ratio and the data relating to the crystal arcing. And in particular may comprise any suitable implementation, to which embodiments of the invention are not limited.

And step 103, executing corresponding seismic anomaly processing on the plurality of Czochralski crystal pulling devices according to the seismic event.

In the embodiment of the invention, after the earthquake event is detected, corresponding earthquake exception processing is automatically executed on a plurality of Czochralski single crystal devices. The earthquake anomaly processing refers to one or a series of processing automatically executed when an earthquake occurs, which is set in advance. For example, the step of the Czochralski crystal growing apparatus is switched to an abnormality processing step, a decrease in the rotation speed of the ingot, a setting of the heater power, a decrease in the rotation speed of the crucible, or any other suitable process, to which the embodiment of the present invention is not limited.

In the embodiment of the invention, if the seismic event is divided into a plurality of seismic events, corresponding seismic exception processing can be preset for each seismic event, so that appropriate processing is adopted for different seismic events.

In addition, in addition to determining the seismic event in the above manner, an externally notified seismic event may be received, or a manually submitted seismic event may be determined, or other information such as the extent of the seismic event may be determined in any other suitable manner. The control system can control the plurality of Czochralski crystal growing apparatuses to automatically execute corresponding seismic anomaly processing according to the seismic anomaly processing.

In the embodiment of the invention, the process steps of the plurality of Czochralski crystal growing apparatuses may be different, for example, some Czochralski crystal growing apparatuses are in a seeding state, some Czochralski crystal growing apparatuses are in a feeder feeding state, some Czochralski crystal growing apparatuses are in a charging bucket lifting state, etc. For each step state of the Czochralski crystal growing apparatus, the corresponding seismic anomaly processing may be preset, so that appropriate processing is adopted for different step states.

In the embodiment of the invention, after the earthquake exception handling is determined, a plurality of Czochralski crystal devices are respectively controlled to execute the corresponding earthquake exception handling, so that the earthquake event is automatically detected in the Czochralski crystal process, and the Czochralski crystal devices can automatically perform the earthquake exception handling.

Referring to fig. 2, a flowchart illustrating steps of an embodiment of a seismic processing method according to the present invention may specifically include the steps of:

step 201, detecting a crystal arcing condition of a plurality of Czochralski crystal growing apparatuses.

In the embodiments of the present invention, the specific implementation manner of this step may be referred to the description in the foregoing embodiments, which is not repeated herein.

Step 202, determining the equipment duty ratio of the Czochralski single crystal equipment with the crystal arcing in the Czochralski single crystal equipment in the constant diameter state according to the crystal arcing conditions of the plurality of Czochralski single crystal equipment.

In embodiments of the present invention, during pulling of a single crystal, crystal arcing begins to occur after the crystal is pulled from the single crystal pulling apparatus. Czochralski crystal apparatus in an isodiametric state are generally in a stable crystal-producing stage during which crystal arcing may occur. The method comprises the steps of firstly obtaining the number of the Czochralski single crystal devices in an equal diameter state, and then determining the device duty ratio of the Czochralski single crystal devices with crystal arcs in the Czochralski single crystal devices in the equal diameter state according to the crystal arc-striking conditions of the Czochralski single crystal devices.

And step 203, determining the seismic event according to the equipment duty ratio.

In embodiments of the present invention, a seismic event may be determined based on the determined device duty cycle. For example, if the device duty cycle exceeds 50%, it is determined that a seismic event has occurred.

In an alternative embodiment of the present invention, determining a specific implementation of the seismic event according to the device duty cycle may include: and if the equipment duty ratio is between a first preset duty ratio and a second preset duty ratio, determining that the earthquake event occurs and the earthquake event is a slight earthquake event, and if the equipment duty ratio exceeds the second preset duty ratio, determining that the earthquake event occurs and the earthquake event is a serious earthquake event. The second preset duty cycle is greater than the first preset duty cycle.

The device duty cycle reaches a first preset duty cycle and it may be determined that a seismic event has occurred. The first preset duty cycle may be set to any suitable preset value, which is not limited in this embodiment of the present invention. If the device duty cycle is between the first preset duty cycle and the second preset duty cycle, the seismic event is determined to be a minor seismic event, because the device duty cycle is relatively smaller at the minor seismic event compared to the severe seismic event.

And if the equipment duty ratio exceeds the second preset duty ratio, determining that the seismic event is a severe seismic event.

According to the equipment duty ratio, not only can whether the earthquake happens or not be detected, but also the intensity of the earthquake event can be detected, so that the earthquake event is finely divided.

And 204, executing corresponding seismic anomaly processing on the plurality of Czochralski crystal pulling devices according to the seismic event.

In an optional embodiment of the present invention, the seismic event is a slight seismic event, and in a specific implementation manner of performing corresponding seismic anomaly processing on the plurality of czochralski crystal devices according to the seismic event, the method may include: acquiring set crystal bar rotating speeds of the plurality of Czochralski crystal pulling devices; determining corresponding crystal bar rotating speed reduction processing according to the set crystal bar rotating speed for each Czochralski crystal pulling device; and respectively executing corresponding crystal bar rotating speed reduction processing on the plurality of Czochralski crystal pulling devices.

After the slight earthquake event is determined, presetting the earthquake abnormality corresponding to the slight earthquake event as crystal bar rotation speed reduction processing. In the specific implementation, a set crystal bar rotating speed is acquired for each Czochralski crystal pulling device, and then corresponding crystal bar rotating speed reduction processing is determined according to the set crystal bar rotating speed. For example, a schematic diagram of an automated process flow at the time of a light earthquake as shown in fig. 3. If the set crystal bar rotating speed is smaller than the set rotating speed threshold value X, determining that the corresponding crystal bar rotating speed reduction processing is that the crystal bar rotating speed is reduced to zero. If the set ingot rotation speed is not smaller than the set rotation speed threshold value X, the corresponding ingot rotation speed reduction processing is determined to reduce the set rotation speed Y on the basis of the current ingot rotation speed.

When a slight earthquake happens, the rotating speed of the crystal bar is automatically reduced, the amplitude of crystal arcing can be reduced, the influence of the crystal arcing on the aspects of single crystal growth and operation control is reduced, the failure rate of products caused by the crystal arcing is reduced, the product quality is ensured, and the loss is reduced.

In an optional embodiment of the present invention, the seismic event is a severe seismic event, and in a specific implementation manner of performing corresponding seismic anomaly processing on the plurality of czochralski crystal devices according to the seismic event, the method may include: acquiring the process step states of the plurality of Czochralski crystal growing apparatuses; determining corresponding seismic anomaly processing according to the step state for each Czochralski single crystal pulling device; and respectively executing corresponding seismic anomaly processing on the plurality of Czochralski crystal devices.
