example 1

[0041] Example 1: Product manufacturing step estimation process

[0042]First of all, the processing module of the auxiliary distribution system first searches for product information from the database of the storage module, including product information of products that have been produced or are in production, and the database also stores the information LayerNum of the number of steps of the total process (Layer) that needs to be done , and StartTime when the product starts to be produced, and CycleTimeLayer, the average production time of each process, it is estimated that the time from the start of production to the back-end process of the product is

[0043] StartTime+LayerNum*CycleTimeLayer.

[0044] Step 2, the calculation module calculates the time for the product to enter the back-end process based on the above information, that is, according to the product production process, the current steps of the product, and the time required for each step, estimate the product ...

example 2

[0046] Example 2: Product allocation and confirmation process

[0047] The calculation module estimates the product information of each process step that needs to be done every day according to its current production status in the packaging and testing factory and its subsequent processes. Then, according to the business scope of each packaging and testing factory and the current and future estimated utilization status of the relevant machines in each process step in the factory, combined with the service performance of each packaging and testing factory and the differences between different customers for these packaging and testing factories The degree of preference, and finally automatically assign each product.

[0048] When the auxiliary distribution system allocates the above distribution, it retrieves the information of the product from the database, as well as the business scope of the packaging and testing factory and the current and future estimated utilization status...

[0059] Example 3: Automatic tracking process of product back-end manufacturing.

[0060] After confirmation, the auxiliary distribution system will automatically track the processing status of these products through the back-end manufacturing execution system BMES, and through data interaction with the front-end manufacturer and the back-end packaging and testing factory, the latest status and history of each product It is continuously stored in its database. Once the confirmed relevant process steps are entered, the system will automatically generate a commission order to notify the relevant personnel of the packaging and testing factory to pick up the goods and subsequent processing when the system finds that a product needs to be entered. The commission method can be in the form of Mail and / or FTP. Of course, the Mail address, FTP address and other information are all pre-defined by the relevant engineers in our factory and pre-stored in the auxiliary distribution system. ...

Abstract

The invention discloses an auxiliary distribution system and an auxiliary distribution method. The auxiliary distribution system comprises the following parts: a memory module, a processing module, an input / output module and a terminal, wherein the memory module is used to store information for product production; the processing module is used to receive the required product information from the memory module, to calculate steps of the product in the next days, to distribute the product and to give notice; the input / output module is used to input the command of the terminal to the auxiliary distribution system and to issue the commands or information to the terminal; and the terminal is used by the user to receive the information output by the auxiliary distribution system and to input the required information. By adopting the novel auxiliary distribution system and the auxiliary distribution method for the semiconductor manufacturing production, the invention has the advantages that the workload of the relevant engineers is greatly reduced, the accuracy of the estimated capacity is improved, and the present and future product production statuses at each process step are known more actually; and the capacity utilization ratio is promoted to be maximized by the automatic distribution and conformation of the product.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing and production, in particular to an auxiliary distribution system and an auxiliary distribution method for semiconductor manufacturing and production. Background technique [0002] In the current semiconductor manufacturing and production industry, in order to improve production efficiency and product quality, many manufacturing enterprises have realized the conversion from traditional manual operation to semi-automatic or even fully automatic operation methods. In the field of semiconductor manufacturing, full automation of production has become a necessary condition for every enterprise to enhance its competitiveness. Due to the further advancement of the division of labor in the design, manufacture, packaging, and testing of the semiconductor industry, cooperation among industries has become more and more important. And how to make the cooperation between the division of la...
