摘要： A chip information character set including a lot ID for chip-marking, which has a smaller number of characters than that of a conventional lot ID used in a fabrication line for a semiconductor device, is generated by coding the conventional lot ID using a decimal numeration system or a 62 decimal numeration system. A wafer identifier for chip-marking having 1-character is generated by coding a conventional number of a wafer using a set of identification symbols. A chip coordinate for chip-marking is having either 1-character or 2-characters is generated by coding a conventional coordinate of a chip in the wafer using the decimal or 62 decimal numeration system. The chip information character set has a simplified form to be written in a relatively short time, thereby increasing a productivity of the semiconductor device.
摘要翻译：通过使用十进制数字对常规批号进行编码，生成包括用于芯片标记的批ID的芯片信息字符集，其具有比用于半导体器件的制造线中使用的常规批号更少的字符数系统或62位十进制数字系统。通过使用一组识别符号对常规数量的晶片进行编码来产生具有1个字符的芯片标记的晶片标识符。通过使用十进制或十六进制数字系统对晶片中的芯片的常规坐标进行编码来生成用于芯片标记的芯片坐标，其具有1个字符或2个字符。芯片信息字符集具有在较短时间内写入的简化形式，从而提高半导体器件的生产率。
