    • A three dimensional thin-film interconnector is fabricated by depositing a dielectric layer onto the surface of a substrate, depositing a layer of conductive material onto the dielectric layer to form a signal plane, depositing a dielectric layer onto the surface of the signal plane, forming a plurality of through holes in the dielectric layer that extend to the signal plane, and filling the through holes with an electrically conductive material to form vias. The sequence of forming a signal plane, depositing a dielectric layer, forming a plurality of through holes, and filling the through holes is repeated until a predetermined number of signal planes and a predetermined arrangement of vias are obtained. The through holes are formed at locations in the dielectric layers corresponding to both predetermined electrical connections and the vias in a preceding dielectric layer. The signal planes are formed at different locations on the substrate. The sequence of signal planes and dielectric layers at the same location on the substrate form a signal plane set which defines a connector. Contact pads are deposited onto the surface of a final dielectric layer and electrically connect with each via. Wires are used to electrically connect the contact pads of one connector to corresponding contact pads of another connector. A portion of the substrate and dielectric layers not comprising a signal plane set is removed, forming electrical connectors flexibly attached by the plurality of wires.
    • 通过在衬底的表面上沉积介电层来制造三维薄膜互连器,在电介质层上沉积导电材料层以形成信号平面,在信号面的表面上沉积电介质层,形成 电介质层中的多个通孔延伸到信号平面,并用导电材料填充通孔以形成通孔。 重复形成信号平面,沉积介电层,形成多个通孔和填充通孔的顺序,直到获得预定数量的信号面和通孔的预定布置。 通孔形成在电介质层中对应于先前电介质层中的预定电连接和通路两者的位置处。 信号面形成在基板上的不同位置。 基板上相同位置处的信号平面和电介质层的顺序形成了限定连接器的信号平面组。 接触焊盘沉积在最终电介质层的表面上并与每个通孔电连接。 电线用于将一个连接器的接触焊盘电连接到另一个连接器的相应接触焊盘。 除去不包括信号平面组的衬底和电介质层的一部分,形成由多个电线柔性附接的电连接器。

    • Novel structures for capacitors which are capable of withstanding heat treatments to at least 400.degree. C. while providing low defect densities and low electrical series resistance in its electrodes are disclosed. In one embodiment of the present invention, a capacitor structure includes a bottom capacitor electrode formed of a first sub-layer of aluminum, a second sub-layer of tantalum nitride, and a third sub-layer of tantalum. The capacitor structure further includes a sputtered dielectric layer of tantalum pentoxide over the tantalum sub-layer of the bottom electrode. The resulting structure is anodized such that the underlying tantalum layer is fully anodized, and preferably such that a portion of the tantalum nitride layer is converted to a tantalum oxy-nitride. The tantalum nitride layer was discovered by the inventors to act as a good high temperature diffusion barrier for the aluminum, preventing the aluminum from migrating into the anodized tantalum pentoxide layer under high temperature processing conditions, where it would chemically reduce the tantalum atoms in the tantalum pentoxide layer and introduce conductive paths of tantalum in the dielectric (tantalum pentoxide) layer. The aluminum layer provides good electrical conductivity for the bottom electrode, and is anodized to fill any pinhole defects in the layers formed above it, thereby increasing manufacturing yields.
    • 公开了一种电容器的新型结构,其能够耐热处理至少400℃,同时在其电极中提供低缺陷密度和低电串联电阻。 在本发明的一个实施例中,电容器结构包括由铝的第一子层,氮化钽的第二子层和钽的第三子层形成的底部电容器电极。 电容器结构还包括在底部电极的钽子层上的五氧化二钽的溅射介电层。 所得到的结构被阳极氧化,使得下面的钽层被完全阳极氧化,并且优选地使得一部分氮化钽层转化为氮氧化钽。 本发明人发现氮化钽层用作铝的良好的高温扩散阻挡层,防止铝在高温加工条件下迁移到阳极氧化的五氧化二钽层中,其中它将化学还原钽中的钽原子 并在介电(五氧化二钽)层中引入钽的导电路径。 铝层为底部电极提供良好的导电性,并被阳极氧化以填充其上形成的层中的任何针孔缺陷,从而提高制造产量。
