Description

System for managing a product distribution of a semiconductor fabricating line}

The present invention relates to a logistics management system used in a semiconductor manufacturing line, for example, a semiconductor assembly line, and more particularly, by eliminating an operator's intervention in the process of issuing an information recording paper, thereby speeding up the process flow and preventing accidents. The present invention relates to a semiconductor manufacturing line logistics management system that enables to easily achieve "efficient management of personnel".

In general, a customer purchasing a semiconductor product generally presents various test conditions in relation to the characteristics of the product. Accordingly, in a production line, a test corresponding to a condition suggested by the customer in each semiconductor product is required. By going through the process, we are working to ensure that the final shipment of semiconductor products will have a function that meets customer needs.

In this case, in the production line, for example, a so-called "logistics management system" consisting of a combination of "warehouses and conveyors" is arranged, and through this, each semiconductor product that has been assembled is classified by, for example, "by test conditions". Finally, each semiconductor product is guided through the test process to meet the customer's requirements.

On the other hand, when such a series of logistical management process proceeds, the semiconductor product inevitably undergoes a process of greatly changing its product information.

In this case, when a series of post-processing processes, for example, a test process is performed, in a situation in which change information of each semiconductor product is not accurately transmitted to a worker who is arranged next, an unexpected process accident may occur.

For example, even though the information is changed to a "device to be tested under the conditions of A" by the logistics management process of the logistics management system, the changed information is not accurately transmitted to the next worker, For a product, for example, when a test procedure under “B condition” is in progress, the finally released semiconductor product does not have a function corresponding to the needs of the customer.

In view of this, conventionally, a worker dedicated to issuance of an "information recording sheet" called "Lot card" is placed in the vicinity of the warehouse, and through this worker, a semiconductor product changed by logistics management. Efforts are being made to ensure that the information in this document is accurately communicated to the next operator.

In this case, the worker who is in charge of issuing the information record sheet, if a series of "product information changes" occur, note the change on the information record sheet mentioned above, and then, for example, the tray By inserting the inside of a carrier box equipped with a tray, it is possible for other workers arranged in the next process to easily grasp the change information of the semiconductor product which has been carried out in the warehouse.

Afterwards, the worker placed in the next process accurately understands the changes of each semiconductor product through the above-described information recording sheet and reflects them in the post-treatment process so that unexpected accidents can be prevented in advance.

However, there are some serious problems in operating such a conventional semiconductor manufacturing line logistics management system.

As described above, conventionally, a worker dedicated to issuance of the information recording paper is arranged in the vicinity of the warehouse, and a series of post-processing steps are performed depending on the information recording paper issued by the worker's manual work. In this case, however, since the issuance of all the information recording sheets is performed by the manual work of the "information record sheet issuing worker", a serious problem arises in that the overall process flow is very slow.

If the wrong information is recorded in the information record sheet by a worker's mistake during the manual operation, this wrong information is reflected in the next post-processing process, which causes a serious problem that an unexpected process accident occurs. do.

Moreover, in the conventional case, since a worker dedicated to issuance of the information recording sheet must be additionally arranged in the warehouse, a serious problem arises that the supply and demand of manpower is not made smoothly.

Accordingly, it is an object of the present invention to automate the issuance of information recording sheets, thereby eliminating the necessity of arranging an "information worker for issuing information recording sheets", thereby inducing rapid progress of the overall process flow.

Another object of the present invention is to exclude the operator's intervention in the process of issuing the information recording sheet, to prevent the process accident due to the operator's mistakes in advance, and to maintain the overall manpower supply and demand system smoothly.

Still other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

1 is an exemplary view showing a semiconductor manufacturing line logistics management system according to the present invention.

2 is an exemplary view showing an information recording sheet issuing machine according to the present invention.

The semiconductor manufacturing line logistics management system according to the present invention for achieving the above object is to classify the semiconductor products by a series of logistics management standards, and then put the sorted semiconductor products in a carrier box to transport the warehouse to the exit side gate And a conveyor belt for conveying the carrier box transported through the exit gate of the warehouse to the outside, a controller for inputting the changed information of the semiconductor product changed during the above-described logistics management process, and connected to the controller online. After the change information of the semiconductor product is inputted from the controller mentioned above, the information recording paper which records this change information is issued, and the information recording paper issuing machine which mounts the information recording paper in the above-mentioned carrier box. In combination.

In the case of the present invention, since the process of issuing the information recording sheet can be automatically proceeded by the information recording sheet issuer, when the present invention is achieved, the production line can smoothly proceed the process of issuing the information recording sheet without the intervention of the operator. As a result, the production line can quickly maintain the overall process flow, can prevent the accident of the process in advance by the operator's mistakes, and smoothly guide the overall manpower management.

Hereinafter, the semiconductor manufacturing line logistics management system according to the present invention with reference to the accompanying drawings in more detail.

As shown in FIG. 1, the semiconductor manufacturing line logistics management system 100 according to the present invention is composed of a combination of a warehouse 10, a conveyor 20, 60, and a controller 50. In this case, the warehouse 10 sorts the semiconductor products by a series of logistics management process, and then serves to load the sorted semiconductor products in the carrier box 80, each of which is provided in the conveyor (20, 60) The conveyor belts 21 and 61 serve to carry the carrier box 80 carried out through the exit gate 11 of the warehouse 10 to the outside.

At this time, the above-mentioned conveyors 20 and 60 are first bent in a state of being connected to each other, for example, "a".

Here, the above-described controller 50 may be connected to the host (not shown) in the warehouse 10 online so that the controller 50 may receive the changed information of the semiconductor product changed in the warehouse 10 in detail.

For example, when a group of semiconductor products are classified by the above-described logistics management process, and the product information is changed to "a device to be tested with a current value of 5V," the controller can receive the corresponding change information in detail. If other groups of semiconductor products are classified by the logistics management process, and the product information is changed to "a device to be tested with a current value of 3.3V", the controller can also receive such change information in detail.

At this time, as shown in the figure, an information recording sheet issuing machine 30 is disposed at the exit gate 11 of the distribution warehouse 10. The information recording sheet issuer 30 receives the change information of the semiconductor product from the controller 50 in a state of being connected online through the controller 50 and the communication line 40 described above, and then records the change information. It is responsible for automatically publishing the record sheet. In this case, the issued information recording sheet is mounted on the carrier box 80 carried out to the exit gate 11 of the distribution warehouse 10.

The arrangement of the information recording sheet issuing machine 30 constitutes the gist of the present invention. Of course, the information recording sheet issuing machine is not disposed at all in the conventional semiconductor manufacturing line logistics management system.

In the conventional case, a worker dedicated to issuing an information recording sheet was placed in the vicinity of the warehouse, and a series of post-processing processes were performed depending on the information recording sheet issued by the worker's manual work, in which case all information recording sheets were issued. Since this process was performed by the manual labor of the worker, the overall process flow was slowed, unexpected process accidents occurred, and overall manpower management was not performed smoothly.

However, in the case of the present invention, as described above, since the issuance process of the information recording paper can be automatically proceeded by the information recording paper issuing machine 30, when the present invention is achieved, the process of issuing the information recording paper without the intervention of an operator is required. It is possible to proceed smoothly, as a result, it is possible to quickly maintain the overall process flow, to prevent the process accident due to the operator's mistakes in advance, it is possible to smoothly guide the overall manpower management.

In this case, as shown in FIG. 2, the above-described information recording sheet issuer 30 is disposed in the main body 31 and the main body 31, and receives the change information of the semiconductor product from the controller 50 mentioned above. And the printer block 32 for printing the change information of the semiconductor product on the information recording sheet 1, and the main body 31 toward the exit gate 11 of the distribution warehouse 10, and to the printer block 32. By a combination of the information recording sheet issuing gates 33 which output the printed information recording sheets 1 to the exit gate 11 side. In this case, the information recording paper 1 outputted from the information recording paper issuing gate 33 is mounted downward in the above-mentioned carrier box 80.

Here, as shown in the figure, at the bottom of the information recording sheet issuing gate 33, a sensor 35 for sensing whether or not the information recording sheet 1 is issued is further mounted. In this case, the controller 50 may quickly determine whether the information recording sheet 1 is issued, the number of copies, etc. according to the sensing operation of the sensor 35.

Hereinafter, the operation of the semiconductor manufacturing line logistics management system according to the present invention will be described in detail with reference to the drawings and description described above.

First, after the semiconductor product has completed a series of logistics management processes carried out in the warehouse 10, mounted on the tray 81, loaded on the carrier box 80, the gate of the exit side of the warehouse 10 ( 11) are taken out. In this case, the conveyor belt 21 disposed in front of the exit gate 11 performs a rapid rotational motion, thereby inducing a rapid straight movement of the carrier box 80 described above. Of course, when such a series of logistics management processes are carried out, semiconductor products inevitably undergo a process in which their product information is greatly changed.

At this time, as shown in FIG. 2, a pair of stoppers 90 is further disposed at the end of the conveyor belt 21, and the stopper 90 has a carrier box 80 with the conveyor belt 21. It serves to prevent the problem of escaping.

On the other hand, when the above-mentioned carrying out process is completed and the carrier box 80 reaches the front side of the information recording sheet issuer 30, the printer block 32 of the information recording sheet issuer 30 is referred to as the "semiconductor product" from the controller 50 described above. After inputting the "change information", the change information of the semiconductor product is printed on the information recording sheet 1 according to the input information.

As in the above-described example, if the semiconductor products loaded on the tray 81 are classified by the above-described logistics management process, and the product information is changed to "a device to be tested with a current value of 5V", the controller ( 50) inputs the information to the information recording sheet issuer 30, and the printer block 32 of the information recording sheet issuer 30 prints the change information of the semiconductor product corresponding to the input information on the information recording sheet 1; Done. As a result, on the information recording sheet 1, the phrase " device in which the test should be carried out at a current value of 5V " is clearly printed.

When the printing process is completed, the information recording sheet issuing gate 33 outputs the information recording sheet 1 on which the printing is completed by the printer block 32 mentioned above to the carrier box 80. In this case, the information recording paper 1 outputted from the information recording paper issuing gate 33 is mounted downward in the above-mentioned carrier box 80.

At this time, as shown in the figure, an output guide body 34 is further formed at the entrance of the information recording paper issuing gate 33. In this case, the information recording paper 1 output from the information recording paper issuing machine 30 is By the guide action of the output guide body 34, it can be correctly mounted in the predetermined position of the carrier box 80. FIG.

When all of the information recording paper 1 issuance process is completed, the carrier box 80 is flowed along the conveyor belt 61 and then, for example, to the automatic transport cart 70 moving along a series of guide lines 71. It is carried to the next process.

Thereafter, the worker disposed in the next process is to know the changes of each semiconductor product through the information recording paper (1) issued through the above-described process, so that a series of post-processing process can be carried out stably.

At this time, as described above, since the process of issuing the information recording sheet is automatically managed by the information recording sheet issuer 30 unique to the present invention, the operator placed in the next process, for example, the testing process, is tested under the condition of "5V. The device that is to be processed may be correctly tested according to the device, and as another example, the device to be tested by the condition of 3.3V may be tested to be exactly the same. As a result, the final semiconductor product to be shipped can have a function that meets the needs of the customer.

As described above, in the present invention, by eliminating the operator's intervention in the process of issuing the information recording paper, it is possible to easily achieve "acceleration of process flow", "prevention of process accident", "efficient management of personnel" and the like.

The present invention has an overall useful effect in the management system of various models for managing the logistics of semiconductor products.
