Description




TECHNICAL FIELD




The present invention relates to a control apparatus and a control method for controlling a semiconductor manufacturing apparatus in a semiconductor manufacturing process and, more particularly, to a method and apparatus for managing apparatus operating condition parameters for adjusting operating conditions of a semiconductor manufacturing apparatus.




BACKGROUND ART




Generally, a semiconductor manufacturing apparatus is a combination of various process chambers each of which performs a semiconductor device manufacturing process, and a transport mechanism, which conveys wafers, is provided between the process chambers and between a cassette that accommodates many wafers and a process chamber.




There are many apparatus operating condition parameters that correspond to a plurality of process chambers and a transport mechanism so that the process chambers and the transport mechanism can adjust the operational conditions of a semiconductor manufacturing apparatus in response to the ordered specifications and the purpose of use of a user.




Additionally, the semiconductor manufacturing apparatus may have a multi-chamber structure as mentioned above, and may be provided with an equipment control device for generally controlling the apparatus in response to the transport mechanism being provided thereto. Additionally, there is a case in which the equipment control device does not only control one semiconductor manufacturing apparatus but also generally control a plurality of semiconductor manufacturing apparatuses. As mentioned above, the semiconductor manufacturing apparatus and a system including semiconductor manufacturing apparatuses have become complicated, and it is desired to efficiently manage the apparatus operating condition parameters of a semiconductor manufacturing apparatus. In this case, the equipment control device is connected to a control device (hereinafter, may be referred to as a machine control device) of the process chambers and the transport mechanism via a network so as to exchange various kinds of information including the apparatus operating condition parameters with the machine device.




Accordingly, conventionally, the apparatus operating condition parameters are stored in a memory apparatus such as a memory apparatus attached to the machine control apparatus or a hard disk apparatus that can be accessed by the machine control apparatus.




Each machine control apparatus has a first memory such as a ROM for storing apparatus control programs and a second memory such as a RAM for storing apparatus operating condition parameter executing table that accommodates the apparatus operating condition parameters referred to by the apparatus control programs during operation. Additionally, each machine control apparatus develops in the above-mentioned second memory via the machine control apparatus the apparatus operating condition parameters stored in the memory apparatus attached to the machine control apparatus or the apparatus operating condition parameters that have been stored in the memory apparatus attached to the machine control apparatus by executing the initialization program.




As mentioned above, according to the conventional technique, the apparatus operating condition parameters are collectively managed, that is, integrally stored in the memory apparatus, and are integrally developed in the second memory of the machine control apparatus.




However, the apparatus operating condition parameters are changed during operation in the delivered party or when version upgrade is made. That is, the apparatus operating condition parameters are adjusted to the standard setting values when the semiconductor manufacturing apparatus is produced, and then adjusted to conform to the order specifications or apparatus specifications at the delivery time. Additionally, a part of the apparatus operating condition parameters may be reset at the delivered site of the semiconductor manufacturing apparatus so as to conform to the operational conditions of the client. As an example, when the client changes the number of arms of the transport mechanism, the standard setting value or the setting value at the delivery time is overwritten by the reset at the delivered site.




However, for example, when the version of the apparatus control programs are upgraded, there may be a case in which the apparatus operating condition parameters must be set back to the setting value at the delivery time or the standard value so as to perform an inspection or initialization of the upgraded apparatus control program. In such a case, since the apparatus operating condition parameters that have been reset at the delivered site are deleted, the apparatus operating condition parameters that have been reset at the delivered site must be memorized so as to perform an input operation of the client oriented setting values after the version upgrade is completed. Such a resetting operation is inconvenient for the operator, and there is a problem in that operation errors of the semiconductor manufacturing apparatus may occur due to input errors.

According to the embodiment of the semiconductor manufacturing apparatus of the present invention, as levels of the above-mentioned apparatus operating parameters provided with a priority level from the standard level peculiar to the above-mentioned semiconductor manufacturing apparatus to the specific level peculiar to a user of the above-mentioned semiconductor manufacturing apparatus, there are provided (1) a set of standard setting values that are parameters peculiar to the above-mentioned semiconductor manufacturing apparatus, (2) a set of setting values at the time of delivery of the apparatus that are the parameters at the delivery time of the above-mentioned semiconductor manufacturing apparatus and (3) a set of client oriented setting values that are parameters adjusted by the client of the above-mentioned semiconductor manufacturing apparatus. Generally, since the values of the parameters become more specific and detailed in the order of (1) the set of standard setting values, (2) the set of the apparatus delivery time setting values and (3) client oriented setting values, it is considered that the priority level is higher in the order of (1), (2) and (3).




In the following description, as examples of the apparatus operating condition parameters, a consideration will be made of parameters that relate to the mechanical structure of the mechanical part of the transport system. As items of the parameters, for example, the following parameters are considered.




Parameter 1: number of arms




Parameter 2: maximum speed of first arm (mm/sec)




Parameter 3: maximum speed of second arm (mm/sec)




Parameter 4: length of guide rail (mm)




Parameter 5: number of stages of cassette




A description will now be given of a managing method of the apparatus operating condition parameters performed in an embodiment of the semiconductor manufacturing apparatus according to the present invention.

FIG. 4

is a flowchart of an example of an operation for storing the apparatus operating condition parameters.




In step


10


, the following standard setting values which are determined according to the design specifications of the semiconductor manufacturing apparatus arte stored in the memory apparatus


214


via the input/output device


216


of the equipment control unit


210


.




(1) set of standard setting values




Parameter 1=2




Parameter 2=500




Parameter 3=400




Parameter 4=1000




Parameter 5=4




Next, when the length of the guide rail is changed from 1000 mm to 800 mm in the order specifications, the following apparatus delivery time setting values, which are determined in accordance with the order specifications of the apparatus, are stored in the memory apparatus


214


in step


12


.




(2) set of apparatus delivery time setting values




Parameter 1=2




Parameter 2=500




Parameter 3=400




Parameter 4=800




Parameter 5=4




Next, the semiconductor manufacturing apparatus delivered to the client is started (step


14


). At this time, the client develops the (1) standard setting values on the memory of the machine control unit


72


for the transport system (step


16


). Next, the 0(2) apparatus delivery time setting values are developed on the memory of the machine control unit


72


for the transport system. At this time, the set of setting values is developed so as to overwrite the (1) standard setting values that have already been developed on the memory (step


18


). Thereby, the data developed on the memory of the machine control unit


72


for the transport system coincide with the (2) apparatus delivery time setting values.




Next, at the client's site, the apparatus operating condition parameters are adjusted while the semiconductor manufacturing apparatus is operated (step


20


). For example, the number of stages of the cassette is changed from 4 to 3. Or, at the client's site, the number of arms is reduced from 2 to 1, or there may be a case in which a large change is applied to the transport system such that one arm is maintained to be fixed. In this case, the corresponding apparatus operating condition parameters are changed, and the changed data is stored as the (3) client oriented setting values in the memory apparatus


214


. At this time, the (3) set of client oriented setting values that are determined in accordance with the purpose of use of the user is as follows.




Parameter 1=1




Parameter 2=500




Parameter 4=800




Parameter 5=3




Since the second arm is not needed due to the reduction of the number of arms to 1, attention must be paid to the fact that the parameter 3, which relates to the moving speed of the second arm, is not set. It should be noted that only the changed parameters may be stored, or a whole set of setting values may be stored




Although, in the above-mentioned description, the set of client oriented setting values is stored in the memory apparatus


214


after the parameters are adjusted by actually operating the semiconductor manufacturing apparatus through the process of step


14


-step


20


, the set of client oriented setting values may be set to the memory apparatus


214


via the input/output device


216


of the equipment control unit


210


separately from the actual operation of the semiconductor manufacturing apparatus.




Next, a description will be given of an operation of the machine control unit


72


for the transport system to execute the apparatus control program with reference to the apparatus operating condition parameters developed on the memory


102


after the semiconductor manufacturing is started and the apparatus operating condition parameters are developed on the memory


102


of the machine control unit


72


for the transport system in a case in which the sets (1)-(3) of the setting values are stored in the memory apparatus


214


of the equipment control unit


210


.

102


of the machine control unit


72


for the transport system, there are: (a) a method of writing final apparatus operating condition parameters in the memory

However, the order of developing the apparatus operating condition parameters can be reversed. That is, a set of parameters having the lowest priority level is developed on the memory first, and, then, a parameter other than parameters of the same priority level that have already been developed on the memory from among the set of the parameters having a next lower priority level is developed on the memory until a set of the parameters having a next lower priority level cannot be obtained from the memory apparatus, and, thereby, the apparatus operating condition parameters can be developed on the memory in an order of priority level of the set of the parameters.




Additionally, the control system performing the management of the apparatus operating condition parameters of the semiconductor manufacturing apparatus according to the present invention can construct each of eh structural requirements by software (program) and stores the software in a disc apparatus or the like so that the apparatus operating condition parameters can be managed by installing the software on a computer if necessary. Further, the constructed program can be stored in a portable recording medium such as a floppy disc or a CD-ROM so that the program is generally used in a case in which the apparatus operating condition parameters are managed.




The present invention is not limited to the specifically disclosed embodiments, and variations and modifications may be made without departing form the scope of the present invention.
