Description

Material management system

The present invention relates to the technical field of material management, and more particularly to a material management system for assisting an integrated circuit manufacturer (IC foundry) to complete material warehousing and return in a highly efficient and systematic manner.

Raw material generally refers to the main raw materials, parts, or components that are directly put into production. According to the operation mode, material management can be divided into transactional management and on-site management. Among them, transactional management includes: material planning, material budget, stock control, quality control, price control, purchase procedure, billing, etc. On-site management includes: warehousing, material acceptance, delivery, return, inspection and testing operations, inventory and warehousing management, picking up, etc. From the breakdown of the classifications listed above, transactional management and on-site management include both inventory control (inventory and warehouse management) and quality control (material acceptance and inspection test operations), so once the transactional management executives If it is the same person as the on-site management executive, it is very likely that there will be operational errors in the stock control and quality control of the materials.

For example, polishing slurry or other chemical liquids and filter media (filters) are used in a large number of chemical mechanical polishing (CMP) equipment in semiconductor processes, and are specially used in special steel cylinders. Gases (eg, NH ₃ or SiH ₄ ) are also widely used in semiconductor process diffusion devices, chemical vapor deposition (CVD) devices, atomic layer deposition (ALD) devices, etching equipment, Doping equipment, ion implant equipment, and sputtering equipment. It is conceivable that the material container of the slurry or other chemical liquid, the filter medium and the special gas is inevitably subjected to the operations of material storage, material inspection, material return, and material collection and use. Therefore, once the materials storage, material inspection, material return, and material collection and use operations do not communicate with the inventory control of the materials, there is a great chance that the material inventory is insufficient.

As can be seen from the above description, it is urgent for an integrated circuit manufacturer to carry out the management of the polishing liquid or other chemical liquid, the filter medium, and the special gas into the warehouse, the program steps, and the synchronization with the recording. In this way, the factory management of the integrated circuit manufacturer can completely and comprehensively monitor and grasp the inventory status of the slurry or other chemical liquid, filter material and special gas through the central control system, so as to avoid the shortage of material inventory. In view of this, the creator of this new type is trying to research and create, and finally develops a material management system of this new type.

The main purpose of the present invention is to provide a material management system, the material management system, comprising: at least one identity message carrying unit, a plurality of item information carrying units, and at least one portable electronic device. The portable electronic device is configured to read the identity message carrying unit to confirm the operation authority of the operator. Moreover, when performing material warehousing and/or returning, the operator needs to operate the portable electronic device to read the material information carried by the item information carrying unit, including: product name (item number), batch number, effective date, With the serial number, the back-end central monitoring system can instantly confirm the inventory status of each material, including whether the material is disabled, whether there is a storage record, whether the expiration date has expired, or whether the material is used by the system to record positive equipment. In this way, it is ensured that all materials are completed in accordance with the regulations of the plant, and materials can be prevented from being returned incorrectly if they are not used or are not completed.

The creator of the present invention provides an embodiment of the material management system, comprising: at least one identity message carrying unit disposed on at least one operator identity card; The item information carrying unit is respectively disposed on a plurality of item receivers, and each item container is provided with a specific item; and at least one portable electronic device has a The reading unit, wherein the portable electronic device can confirm whether the operator holding the operator identity card has the item by reading the identity message carrying unit The warehousing and warehousing permission of the container; wherein, by the reading unit, the portable electronic device can confirm one of each item container by reading the item information carrying unit status.

In order to more clearly describe a material management system proposed by the present invention, the preferred embodiments of the present invention will be described in detail below with reference to the drawings.

The plurality of item information carrying units (31a, 31b, 31c) are respectively disposed on a plurality of different kinds of item containers (3a, 3b, 3c), and each item container 3a is Separate a specific item. For example, FIG. 1 shows that a first item message carrying unit 31a is disposed on one of the chemical fluid polishing liquids 3b, and the container 3a is filled with a chemical fluid polishing liquid. Specifically, the container 3a may also contain other chemical liquids such as chemical polishing liquids and the like. Moreover, FIG. 1 further shows that a second item information carrying unit 32a is disposed on a gas cylinder 3b, and the gas cylinder 3b is filled with a special gas (for example, NH ₃ or SiH ₄ ). Furthermore, FIG. 1 further shows that a third item information carrying unit 32c is disposed on a filter housing 3c (or a filter housing), and the filter housing 3c is loaded with grinding. Liquid or other chemical liquid filter. That is to say, different item message carrying units (31a, 31b, 31c) are placed on the corresponding type of item containers (3a, 3b, 3c).

In particular, each item message carrying unit (31a, 31b, 31c) carries a plurality of basic messages about the particular item, including: a item number, a batch number, a serial number, and a Effective date. For example, the item number can be English, a number, or a combination of the two to briefly describe the name of the chemical fluid polishing liquid, the slurry or other chemical liquid filter (filter material), or the special gas. It can be inferred that the type of the item information carrying unit is not limited to the first item information carrying unit 31a, the second item information carrying unit 31b and the third item information carrying unit 31c, and the type thereof. The quantity on the basis is determined by the number of types of specific items that are included in the material management system. On the other hand, the unit "at least one" is used to indicate that the number of the identity message carrying unit 21 is one or more; that is, the exact number of the identity message carrying unit 21 is determined by the operator identity card 2 quantity.

According to the design of the present invention, the portable electronic device 5 has a reading unit 51. And, by the reading unit 51, the portable electronic device 5 can confirm the inventory status of each item container 3a by reading the item information carrying units (31a, 31b, 31c). . The inventory status includes, but is not limited to, whether the batch number of the specific item (material) has been disabled, the batch number of the specific item (material) has an inbound record, or whether the storage date of the specific item (material) has exceeded The effective date, whether the specific item (material) has been used, or whether the specific item (material) is currently used by a specific machine, to control various consumables (materials). Moreover, as shown in FIG. 1, the portable electronic device 5 communicates with a central monitoring system CSRC through a transceiver device 6 to enable the central monitoring system CSRC to monitor and master each item container (3a, The inventory status of 3b, 3c), wherein the communication protocol of the transceiver 6 can be implemented by a wired network, a wireless network (WIFI), a mobile network (3G/4G/5G) or Bluetooth, but This is not a limitation.

Although FIG. 1 shows that the identity message carrying unit 21 and the item message carrying units (31a, 31b, 31c) are both 1D barcodes, the message carrying unit should not be limited thereby.

When the present invention is actually applied, the identity message carrying unit 21 and the item message carrying units (31a, 31b, 31c) may be any of the following: graphics, characters, letters, numbers, one-dimensional barcodes ( 1D barcode), 2D barcode, Chinese-sensible code, QR code, matrix barcode (Maxicode), RFID tag, NFC tag, a combination of the above, or both The combination. Taking a 1D barcode as an example, the item message carrying units (31a, 31b, 31c) can be made by a Code 39 barcode generator and make different item message carrying units (31a, 31b, 31c). The item number (product name), lot number, serial number, and expiration date of the specific item contained in the corresponding item container (3a, 3b, 3c). It should be particularly noted that in order to facilitate the clear reading of the product name, batch number, expiration date, and serial number of the portable electronic device 5, the one-dimensional bar code of the item message carrying unit 31 must be created in the adjacent two. A basic seperating character is inserted between the basic messages, for example: %, $, /, ~, !, @, #, ^, &, *, (,), -, _, |, {, },?,<,>, \, [,] or +.

It is conceivable that the message carrying unit (21, 31a, 31b, 31c) corresponding to different implementations, the reading unit 51 of the portable electronic device 5 can be any of the following: an RFID tag reader, NFC tag reader, image recognizer, one-dimensional bar code reader, two-dimensional bar code reader, Hanxin code reader, QR code reader, matrix bar code reader, or image capture device.

It should be noted that although the portable electronic device 5 can confirm whether the operator holding the operator identity card 2 has the right to perform material storage/outbound by reading the identity message carrying unit 21, it is considered to be low. The operator of the rank may use the operator's identity card 2 of the higher rank or the engineer's operator ID card 2 to carry out the storage or return of the item. This new type adds a so-called electronic token unit to the material management system (Electronic token). Unit 8; wherein the electronic token unit 8 stores a One-time password (OTP). In particular, after the portable electronic device 5 completes the reading of the identity message carrying unit 21, the central monitoring system CSRC can request the operator to provide the electronic token unit 8 through the portable electronic device 5; The portable electronic device 5 can repeatedly confirm whether the operator holding the operator identity card 2 has the authority to carry in and out of the material by means of accessing the one-time authentication code, thereby avoiding the high-ranking factory manager or The engineer's operator ID card 2 was used to carry out the handling of the item or return the item indiscriminately. The present invention does not limit the implementation of the electronic token unit 8. As shown in FIG. 2, the electronic token unit 8 may be: a Bluetooth electronic device, a USB electronic device, an NFC tag, or an RFID tag. And after the portable electronic device 5 completes the access of the one-time authentication code from the electronic token unit 8, a token code generating unit (not shown) inside the portable electronic device 5 A set of one-time authentication codes is regenerated and written into the electronic token unit 8, thereby improving the operation authority of the machine 4.
