  • Patent number: 11705396
    Abstract: Embodiments of the disclosure provide a method to form an air gap structure. An opening is formed in a first dielectric layer between adjacent conductors. A first dielectric layer is formed over the opening to fill a first portion of the opening. A remainder of the opening is free of the first dielectric layer. A second dielectric layer is formed on a top surface of the first dielectric layer, with a remainder of the opening unfilled. The second dielectric layer is devoid of wiring. The remainder of the opening below the second dielectric layer defines an air gap structure. A wiring layer is formed above the air gap structure.

  • Patent number: 11127678
    Abstract: A structure includes an air gap structure including: an opening in a first dielectric layer between adjacent conductors, and a non-conformal dielectric layer over the opening. In some cases, the non-conformal dielectric layer narrows an end portion of the opening of the air gap but may not seal the opening. In other cases, the non-conformal layer may seal the end portion of the opening and include a seam therein. The air gap structure may also include a conformal dielectric layer on the non-conformal dielectric layer. The conformal layer either seals the end portion of the opening or, if present, seals the seam. The structure may also include a wiring layer over the air gap structure.

  • Patent number: 10169525
    Abstract: A metal interconnect structure, a system and method of manufacture, wherein a design layout includes results in forming at least two trenches of different trench depths. The method uses a slightly modified BEOL processing stack to prevent metal interconnect structures from encroaching upon an underlying hard mask dielectric or metallic hard mask layer. Thus two trench depths are obtained by tuning parameters of the system and allowing areas exposed by two masks to have deeper trenches. Here, the BEOL Stack processing is modified to enable two trench depths by using a hardmask that defines the lowest etch depth. The design may be optimized by software which optimizes a design for electromigration (or setup timing violations) by utilizing secondary trench depths, checking space opportunity around wires, pushing wires out to generate space and converting a wire to deep trench wire.
