SEMI Font, also known as SEMI OCR font, is used for marking silicon wafers in the semi-conductor industry. The SEMI font character set include 26 uppercase letters, 10 numbers, dash and period. Their shapes and dimensions are specified by SEMI M12/M13 standard, which was approved by Global Traceability Committee and North American Traceability Committee. When used in “single-density” mode, laser scribers use a dot matrix of 5 dots horizontal and 9 dots vertical, in “double-density” mode, the matrix is 10 dots horizontal and 18 dots vertical. == References == *(semi.org ) *(barcodesoft.com ) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「SEMI font」の詳細全文を読む スポンサード リンク
