Abstract: Methods for preventing fin bending in FinFET devices and related devices are provided. Embodiments include forming fins in a substrate; forming a non-conformal sacrificial layer over and between the fins to structurally conjoin the fins or an array of fins for structural integrity; forming a first gap-fill dielectric over the sacrificial layer and fins; recessing the first gap-fill dielectric to expose an upper portion of the fins and sacrificial layer; etching the sacrificial layer to expose the fins; forming a second gap-fill dielectric over the first gap-fill dielectric and over and between the fins; and recessing the second gap-fill dielectric to expose the upper portion of the fins.

Abstract: A method of forming an amorphous carbon (aC) layer as a barrier layer for preventing etching of metals in a dual damascene metallization process and the resulting device are provided. Embodiments include forming an inter-layer dielectric (ILD) layer over a substrate with the first ILD having recesses for a first metallization layer. Then forming a TaN barrier layer and Co liner in the recesses, filling the recesses with a metal, forming a Co cap layer over the metal and forming a conformal aC layer over the substrate are accomplished. Furthermore, an Nblock layer, an ILD layer and a metal hard mask layer completes the stack on top to the aC layer. Subsequently, the embodiments include etching vias through this stack down to the aC layer, thereby protecting the first metallized layer.

Abstract: The present disclosure relates to semiconductor structures and, more particularly, to seamless metallization structures and methods of manufacture. A structure includes: a contact opening formed in an oxide material and in alignment with an underlying structure; a metal liner lining the sidewalls and bottom of the contact opening, in direct electrical contact with the underlying structure; a conductive liner on the metal liner, within the contact opening; and tungsten fill material on the conductive liner and within the contact opening.

Abstract: A method of forming a finFET structure having an ion implanted intermediate region next to the channel region of a finFET gate. The intermediate region is formed in a manner to reduce or eliminate migration of the dopant to undoped regions of the finFET thus forming abrupt finFET junction.
