A semiconductor device and methods for protecting a semiconductor device.
In an example, the semiconductor device may include a semiconductor
substrate including at least one electrostatic discharge (ESD) protection
device, at least one metal interconnection line connected to the at least
one ESD protection device through a conductive plug and a passivation
layer disposed on less than all of the metal interconnection line. In an
example method, a semiconductor device may be protected by diverting at
least a portion of an electron build-up from an accumulation point to one
or more protective circuits along one or more conductive paths, the
electron build-up, without the diverting, sufficient to cause an ESD at
the accumulation point. In another example, a semiconductor device may be
protected by exposing one or more conductive lines to a fuse opening to
avoid an ESD by diverting an electron build-up at the fuse opening to one
or more ESD protection devices.
