LASER MARKING DEVICE FOR INTEGRATED CIRCUIT DEVICE

PURPOSE:To prevent the generation of a deviated or defective marking position in its outside view by correcting the position of the marking automatically. CONSTITUTION:A laser beam scanning range 3 formed with a marking character column direction and a direction intersecting with the direction is calculated, thereby automatically correcting marking so that the characters 4 may be centered in a marking area 2. This construction makes it possible to prevent the generation of a marking whose outside view is unattractive or defective in terms of products where the number of marking characters or marking character columns to ICI is different.
