Abstract:
Embodiments described herein provide for a method of forming an etch selective hardmask. An amorphous carbon hardmask is implanted with various dopants to increase the hardness and density of the hardmask. The ion implantation of the amorphous carbon hardmask also maintains or reduces the internal stress of the hardmask. The etch selective hardmask generally provides for improved patterning in advanced NAND and DRAM devices.

A method of forming an interconnect structure for semiconductor or MEMS structures at a 10 nm Node (16 nm HPCD) down to 5 nm Node (7 nm HPCD), or lower, where the conductive contacts of the interconnect structure are fabricated using solely subtractive techniques applied to conformal layers of conductive materials.
Abstract:
Methods for making a nanocrystalline diamond layer are disclosed herein. A method of forming a layer can include activating a deposition gas comprising an alkane and a hydrogen containing gas at a first pressure, delivering the activated deposition gas to the substrate at a second pressure which is less than the first pressure, forming a nanocrystalline diamond layer, treating the layer with an activated hydrogen containing gas to remove one or more polymers from the surface and repeating the cycle to achieve a desired thickness.

Abstract:
Implementations of the present disclosure generally relate to the fabrication of integrated circuits, and more particularly, to methods for forming a layer. The layer may be a mask used in lithography process to pattern and form a trench. The mask is formed over a substrate having at least two distinct materials by a selective deposition process. The edges of the mask are disposed on an intermediate layer formed on at least one of the two distinct materials. The method includes removing the intermediate layer to form a gap between edges of the mask and the substrate and filling the gap with a different material than the mask or with the same material as the mask. By filling the gap with the same or different material as the mask, electrical paths are improved.
