摘要 |
The invention is directed to a method for checking a die seal ring on a layout. The method comprises steps of receiving a digital database of a layout corresponding to at least a device with a text information corresponding to the layout. Tape-out information corresponding to the layout is received. A checking process is performed according to the digital database of the layout and the tape-out information and, meanwhile, a mask design procedure for designing a mask pattern corresponding to the layout is performed by using the digital database of the layout, the text information and the tape-out information. A result of the checking process is recorded in an inspection table corresponding to the layout. |
