  • Patent number: 7745905
    Abstract: Provided is a semiconductor device having an electric fuse structure which receives the supply of an electric current to be permitted to be cut without damaging portions around the fuse. An electric fuse is electrically connected between an electronic circuit and a redundant circuit as a spare of the electronic circuit. After these circuits are sealed with a resin, the fuse can be cut by receiving the supply of an electric current from the outside. The electric fuse is formed in a fine layer, and is made of a main wiring and a barrier film. The linear expansion coefficient of each of the main wiring and the barrier film is larger than that of each of the insulator layers. The melting point of each of the main wiring and the barrier film is lower than that of each of the insulator layers.

  • Patent number: 7745855
    Abstract: An integrated eFUSE device is formed by forming a silicon “floating beam” on air, whereupon the fusible portion of the eFUSE device resides. This beam extends between two larger, supporting terminal structures. “Undercutting” techniques are employed whereby a structure is formed atop a buried layer, and that buried layer is removed by selective etching. Whereby a “floating” silicide eFUSE conductor is formed on a silicon beam structure. In its initial state, the eFUSE silicide is highly conductive, exhibiting low electrical resistance (the “unblown state of the eFUSE). When a sufficiently large current is passed through the eFUSE conductor, localized heating occurs. This heating causes electromigration of the silicide into the silicon beam (and into surrounding silicon, thereby diffusing the silicide and greatly increasing its electrical resistance. When the current source is removed, the silicide remains permanently in this diffused state, the “blown” state of the eFUSE.

    Abstract: A method is used in processing structures on or within a semiconductor substrate using N series of laser pulses to obtain a throughput benefit, wherein N?2. The structures are arranged in a plurality of substantially parallel rows extending in a generally lengthwise direction. The N series of laser pulses propagate along N respective beam axes until incident upon selected structures in N respective distinct rows. The method determines a joint velocity profile for simultaneously moving in the lengthwise direction the N laser beam axes substantially in unison relative to the semiconductor substrate so as to process structures in the N rows with the respective N series of laser pulses, whereby the joint velocity profile is such that the throughput benefit is achieved while ensuring that the joint velocity profile represents feasible velocities for each of the N series of laser pulses and for each of the respective N rows of structures processed with the N series of laser pulses.

  • Patent number: 7608910
    Abstract: 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.
