Abstract
A semiconductor chip has a first ground line for maintaining a stable ground potential for the internal circuit. The first ground line is connected to a second ground line disposed on a scribe region of the semiconductor chip via a bonding pad, which is connected to an external lead frame. I/O circuit has a third ground line directly connected to the second ground line without passing the bonding pad. The noise propagated from the third ground line to the first ground line is reduced by passing the noise through the bonding pad.
