Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, the embodiment of the invention discloses a method for disposing an air leakage alarm of a purifying cabinet, which comprises the following steps:
determining first data related to the leaked gas and second data related to the purifying cabinet according to the leakage alarm signal of the purifying cabinet;
and generating a gas leakage alarm treatment scheme according to the first data and the second data, and executing the gas leakage alarm treatment scheme.
Various gas leakage detectors, such as Horniwell MIDAS series detectors, are arranged in the purification cabinet, when gas leakage is detected, gas leakage alarm signals can be sent to corresponding processing components, and the processing components can determine relevant data of the leaked gas and relevant data of the purification cabinet according to the gas leakage alarm signals, so that the most suitable gas leakage alarm treatment scheme is determined, and a better gas leakage alarm treatment effect of the purification cabinet is obtained.
The air leakage detector can be arranged on the inner wall of the purifying cabinet, the input interface and the output interface of the purifying cavity of the purifier, and the like, and the latter is preferred.
In some embodiments, the determining the first data of the leaking gas according to the leakage alarm signal of the purifying cabinet includes:
determining the identity code of the purification cabinet according to the air leakage alarm signal, and calling the gas input record of the purification cabinet according to the identity code;
and determining the type code of the leakage gas according to the gas input record, and obtaining the first data according to the type code.
In this embodiment, the air leakage detector is associated with the purifying cabinet where the air leakage detector is arranged in advance, so that the identity code of the purifying cabinet with air leakage can be determined according to the air leakage alarm signal, and accordingly, the gas input record of the purifying cabinet in the corresponding period can be further scheduled, and the type code of the leaked gas can be further determined. The different codes may indicate on the one hand the specific type of leakage gas and on the other hand also the risk of leakage gas and the proper way of handling the leakage.
It should be noted that, according to the actual requirement of production, the purifying cabinet needs to perform purifying operation on different types of gases, and only needs to perform purging operation after one type of gas is purified. The system records information corresponding to the type of gas input to each purifying cabinet and specific time.
In some embodiments, the determining a type code of the leaking gas from the gas input record comprises:
determining first working state data of the purifying cabinet according to the second data, and determining a first period according to the first working state data;
and carrying out matching calculation on the gas input records according to the first time period to determine the type codes and the type quantity of the leaked gas.
In this embodiment, the second data related to the purifying cabinet includes an operating state of the purifying cabinet, and the operating state mainly includes a purifying stage and a purge and exhaust stage. If the purifier is operated in the purification stage, the purification chamber contains only a single gas, while in the purge-exhaust stage, the purification chamber is a mixed gas consisting of at least two gases. The gas herein refers to the bulk of the process gas and does not contain impurity gases therein.
Aiming at the two situations, the invention determines the first time period for tracing according to the working state data of the purifier, and then calculates the type and the type quantity of the gas input into the purifier from the gas input record according to the first time period, thereby being beneficial to the subsequent determination of a more reasonable gas leakage alarm treatment scheme.
In some embodiments, the generating a leakage alarm handling scheme from the first data and the second data comprises:
if the type code is single, determining a first alarm scheme and a first treatment scheme according to the type code;
if the type code is non-unitary, a second alarm scenario and a second treatment scenario are determined from the type code.
In this embodiment, when the gas input recorded in the first period is a single gas type, for example, the gas of the same type is input only once or multiple times in the first period, the appropriate alarm scheme and treatment scheme may be determined only according to the specific type attribute of the gas. If the gas input recorded during the first time period is of a non-single gas type, then the appropriate alarm and treatment schemes need to be determined based on the specific type properties of each adjacent gas.
For example, if the gas is only inert gas/rare gas, an alarm signal may be sent to a specified alarm, and the inert gas/rare gas absorption pump may be controlled to operate so as to recover the inert gas/rare gas to a specified recovery bottle. If the gas contains corrosive gas in addition to inert gas, an alarm signal is sent to a designated alarm, and the corrosive gas absorption pump is controlled to work so as to discharge the corrosive gas to the disposal device, and the like. Of course, the absorption pump may also be followed by a gas separation pump to separate and reuse some of the separable leakage gas. The specific treatment scheme may be determined based on the type of gas leaked, and the present invention may not be particularly limited.
The alarm can be an audible and visual alarm arranged on the purifying cabinet body, an alarm indication button in a monitoring interface on a monitoring terminal of a monitoring center, even mobile alarm equipment equipped by field personnel, and the like, and the invention is not particularly limited.
In some embodiments, the length of the first period is determined from an efficiency parameter of the purge exhaust of the purification cabinet.
In this embodiment, the purifier equipped with the purifying cabinet has different efficiency of purging and exhausting, and the purifier also has different efficiency parameters due to the impurity interference characteristic of the previous input gas and purging and exhausting difficulty, and the efficiency parameters reflect the duration of purging and exhausting. According to the invention, the length of the first period is determined according to the efficiency parameter of the purge and exhaust of the purification cabinet, the length of the first period is inversely related to the efficiency parameter, namely, the higher the efficiency parameter is, the faster the purification cabinet is exhausting the prior input gas, when the purification cabinet is at a certain degree, the later input gas can be determined as the leakage gas, otherwise, the prior input gas and the later input gas which are adjacent in input time are treated as the leakage gas.
Obviously, the length of the first period is a scale of going back forward with reference to the current time or the time when the air leakage alarm signal is received.
In some embodiments, the second data relating to the purification cabinet further comprises second operational status data of a gas consuming device;
the generating a leakage alarm handling scheme from the first data and the second data comprises:
evaluating the job completion probability of the gas consuming device in a second period according to the second working state data, and optimizing the first treatment scheme or the second treatment scheme according to the job completion probability so as to contain a gas valve closing sub-scheme;
and the gas valve closing time of the gas valve closing sub-scheme is determined according to the operation completion probability.
In this embodiment, the purified gas outputted from the purifying cabinet is used by the semiconductor manufacturing apparatus, and the semiconductor manufacturing apparatus may be in different production stages when the purifying cabinet leaks. In view of this, the present invention further analyzes the second operating status data of the semiconductor manufacturing apparatus and evaluates whether it is capable of completing the current operation process within the second time period and accordingly determines when to close the input and/or output gas valves of the purification cabinet.
The length of the second period may be determined according to parameters such as purification efficiency of the purifier, leakage rate, gas pressure of a gas pipeline of the gas utilization device, gas flow rate, and the like. Obviously, the second period is used to characterize the expected duration of time that the purification cabinet is able to supply stable gas to the semiconductor manufacturing equipment at the moment of occurrence of the leak.
In some embodiments, the evaluating the job completion probability of the gas consuming device in the second period according to the second operating state data includes:
calculating to obtain air supply prediction data and operation task attribute data of the air utilization equipment in the second period according to the second working state data;
and evaluating the job completion probability of the gas using equipment in a second period according to the gas supply prediction data and the job task attribute data.
In this embodiment, the task attribute data of the semiconductor manufacturing apparatus may be used to analyze the independence of the current task, for example, if the second period includes tasks for different wafers, the independence of the current task is high, i.e. the influence of the interrupted current task is small; if the second period includes the task for a plurality of steps of a single wafer, the independence of the current task is low, i.e., the influence of the interrupted current task is large.
Aiming at the situation, the invention calculates the gas supply prediction data according to the second working state data, namely, the purifying cabinet can still supply the specific performance parameters of the purified gas to the semiconductor manufacturing equipment under the condition of gas leakage; then, job task attribute data of the semiconductor manufacturing equipment is calculated according to the second working state data, wherein the job task attribute data is mainly characterized by the index independence. Then, the job completion probability is determined according to the air supply prediction situation and whether the current job task can be interrupted.
The following are illustrated:
the gas supply prediction data indicate that the purifying cabinet can only supply gas to the first moment above the gas supply index after gas leakage.
If the second period includes the operation tasks for different wafers, and the operation task for the current wafer can be finished at a second time before the first time, the operation completion probability can be judged to be high, and the operation task of the semiconductor manufacturing equipment is temporarily interrupted by executing the gas valve closing sub-scheme at a proper time after the second time; if the task for the current wafer can be completed at a third time after the first time, it can be determined that the task completion probability is low, and the gas valve closing sub-scheme can be executed at a proper time earlier than the first time, that is, the task for the current wafer is abandoned.
If the second period includes the operation tasks of a plurality of processes for a single wafer and all the processes for the current wafer need to be finished at a fourth time before the first time, the operation completion probability can be judged to be high, and the operation tasks of the semiconductor manufacturing equipment can be temporarily interrupted by executing the gas valve closing sub-scheme at a proper time after the fourth time; if the task for the current wafer can be completed at the fifth time after the first time, it may be determined that the task completion probability is low, and the gas valve closing sub-scheme may be performed at a suitable time earlier than the first time, that is, the task for the current wafer is abandoned.
