  • Publication number: 20260068690
    Abstract: A method of forming a patterned metal layer on a substrate includes identifying at least one distortion zone in a design pattern of metal structures causing a Z-direction displacement of the substrate, inserting metal fill shapes as a fill pattern into the design pattern to reduce the Z-direction displacement in the at least one distortion zone, and forming the metal structures and the metal fill shapes on the substrate as the patterned metal layer. The method may further include calculating bond strength of the substrate based on the design pattern and the fill pattern and adjusting surface area of the metal fill shapes to increase the bond strength. A bonded substrate structure may then be formed by directly bonding a dielectric material of the patterned metal layer of the substrate to an additional substrate.

    Abstract: Aspects of the present disclosure provide a method for chemical mechanical polishing (CMP) iso-dense bias compensation using z-height. For example, the method can include forming a dielectric material on a substrate within a first region to form one or more first dielectric layers that are spaced from one another, and forming on a first one of the first dielectric layers a first height correction layer that has a first height that is determined based on a first pattern density of the first region.

  • Publication number: 20250191970
    Abstract: A method of patterning a substrate includes forming a hardmask over an underlying layer supported by a substrate, forming antispacer trenches over the hardmask, and forming fully self-aligned vias (FSAVs) extending from the hardmask into the underlying layer. The hardmask includes hardmask line features defining hardmask trenches extending in a first direction. The antispacer trenches extend in a second direction nonparallel to the first direction. The FSAVs extend into the underlying layer at intersections of the hardmask trenches and the antispacer trenches. The FSAVs are self-aligned on two sides by sidewalls of the hardmask trenches and self-aligned on the remaining sides by sidewalls of the antispacer trenches.
