    • PURPOSE: An identification method is provided to identify causes of defects using a standardized qualitative method during in-process inspection of a wafer, by assigning generalized symbols to attributes of a single subset of a plurality of database objects corresponding to feature attributes, ad storing identifiers corresponding to features in a database. CONSTITUTION: A methodology is provided for qualitatively identifying features of an article, such as defects on the surface of a semiconductor substrate, with a string of symbols, such as numbers, according to relevant defect characteristics and information relating to the processing tools visited by the wafer, including reliability information. The identification sequences of all defects are stored in a database, where they are easily compared with other correspondingly identified defects. The identification sequence also includes a number representative of the wafer's last-visited processing tool, thereby associating the defect with a tool. After the defect is investigated and determined as being caused by a particular fault of the tool, this information is stored and linked to the defect's identification sequence.
    • 目的:提供一种识别方法,通过将通用符号分配给与特征属性相对应的多个数据库对象的单个子集的属性,广告存储标识符,通过标准化的定性方法来识别晶片的原因, 对应于数据库中的功能。 规定:提供了一种方法,用于根据相关的缺陷特征以及与所访问的处理工具有关的信息,定性地识别物品的特征,例如半导体衬底的表面上的缺陷,具有一串符号,例如数字 晶圆,包括可靠性信息。 所有缺陷的识别序列都存储在数据库中,可以方便地与其他相应识别的缺陷进行比较。 识别序列还包括表示晶片最后访问的处理工具的数字,从而将缺陷与工具相关联。 在缺陷被调查并确定为由工具的特定故障引起之后,该信息被存储并链接到缺陷的识别序列。

    • PURPOSE: A production control system using an RFID(Radio-Frequency Identification) and a MES(Manufacturing Execution System) and a controlling method thereof are provided to improve the efficiency of a task by automatically giving useful information for process analysis to a manager using collected data. CONSTITUTION: A database(210) stores the state and positional information data about the direct factor of production according to the time unit among different data generating in the process. An application module(170) decides a current operating condition from the status and position information saved in the database. An application module calculates statistical values from status, position information and current operating condition data. A user interface unit(180) displays a simple graphical form so that an operator can easily recognize and deal the problem of a process. Position information data is collected by the RFID and the status information data is collected by the MES. The application module includes a status recognizing unit(230), an analyzing unit(240) and a reason finding unit(250).
