  • Patent number: 11177167
    Abstract: Compositions of matter, compounds, articles of manufacture and processes to reduce or substantially eliminate EM and/or stress migration, and/or TDDB in copper interconnects in microelectronic devices and circuits, especially a metal liner around copper interconnects comprise an ultra thin layer or layers of Mn alloys containing at least one of W and/or Co on the metal liner. This novel alloy provides EM and/or stress migration resistance, and/or TDDB resistance in these copper interconnects, comparable to thicker layers of other alloys found in substantially larger circuits and allows the miniaturization of the circuit without having to use thicker EM and/or TDDB resistant alloys previously used thereby enhancing the miniaturization, i.e., these novel alloy layers can be miniaturized along with the circuit and provide substantially the same EM and/or TDDB resistance as thicker layers of different alloy materials previously used that lose some of their EM and/or TDDB resistance when used as thinner layers.

  • Patent number: 11171043
    Abstract: Methods and architectures for IC interconnect trenches, and trench plugs that define separations between two adjacent trench ends. Plugs and trenches may be defined through a multiple patterning process. An upper grating pattern may be summed with a plug keep pattern into a pattern accumulation layer. The pattern accumulation layer may be employed to define plug masks. A lower grating pattern may then be summed with the plug masks to define a pattern in trench ILD material, which can then be backfilled with interconnect metallization. As such, a complex damascene interconnect structure can be fabricated at the scaled-down geometries achievable with pitch-splitting techniques. In some embodiments, the trenches are located at spaces between first spacer masks defined in a patterning process associated with the first grating pattern while the plug masks are located based on a tone-inversion of second spacer masks associated with the second grating pattern.

A hole through which the through-silicon via is to be stretched is created and an over-etching process is carried out on a wiring layer including the line.

After the through-silicon via has been connected to the line made of aluminum through the member which is a connection area, the connection area is alloyed in a thermal treatment in order to electrically connect the through-silicon via to the line. Thus, it is possible to reduce variations of a resistance between the through-silicon via and the line and also improve wiring reliability as well.
