    摘要: A method of forming an interconnection in a semiconductor device includes forming a first liner in a dielectric layer therein; depositing a tungsten filler on top of the first liner; performing chemical mechanical planarization (CMP) to smooth out and remove the first liner and tungsten filler from the semiconductor's exposed surface; selectively removing the first liner and tungsten filler in the via; wherein the selective removing results in the first liner and the tungsten filler being removed in an upper region of the via; forming a second liner in the upper region of the via and tungsten filler; selectively removing the second liner from the tungsten filler; forming a copper seed layer on top of the tungsten filler; depositing a copper filler on top of the copper seed layer; and performing chemical CMP to smooth out and remove the second liner and copper filler from the semiconductor's exposed surface.

    摘要: A static redundancy arrangement for a circuit using a focused ion beam anti-fuse methodology which reduces the circuit layout area and the switching activity compared to a prior art dynamic redundancy scheme, resulting in less power, a simpler design and higher speed. Focused ion beam anti-fuse methodology is used to program redundancy for circuits, particularly wide I/O embedded DRAM macros. An anti-fuse array circuit is comprised of a plurality of anti-fuse programming elements, each of which comprises a latch circuit controlled by a set input signal, and an anti-fuse device which is programmed by a focused ion beam.
