  • Publication number: 20250201557
    Abstract: Methods for forming bilayer hardmasks are disclosed as well as methods for forming semiconductor structure using such bilayer hardmasks. The methods disclosed include performing a first cyclical deposition process to form a first hardmask layer and performing a second cyclical deposition process to form a second hardmask layer directly on the first hardmask layer. The methods also include forming CMOS structures using a bilayer hardmask.

  • Publication number: 20250079160
    Abstract: Methods and systems are disclosed for depositing an oxide in a recess of a substrate, including providing the substrate in a chamber, the substrate including at least one opening to the recess where the at least one opening is bordered by a perimeter in a surface area adjacent to and outside of the recess, where the recess includes an inner surface, pulsing an inhibitor into the chamber to preferentially deposit the inhibitor in a portion of the recess adjacent to at least one opening of the recess and on at least a portion of the surface area, pulsing a precursor into the chamber to chemisorb to the inner surface within the recess, pulsing an oxygen species into the chamber to form the oxide within the recess upon contact with the chemisorbed precursor, and repeating the above recited steps to deposit the oxide to a desired thickness level within the recess.

  • Patent number: 11851757
    Abstract: Coated nanofibers and methods for forming the same. A magnetic nanofiber is formed and a barrier coating is deposited on the magnetic nanofiber by atomic layer deposition (“ALD”) process. The coated nanofiber may include a reduced magnetic nanostructure and a barrier coating comprising a first oxide coating on the nanofiber, the coating being non-reactive with the magnetic polymer nanofiber, the barrier coating have a thickness of 2 nm to 12 nm.

  • Patent number: 11773488
    Abstract: ALD and p-CVD methods to generate MgB2 and MgB2-containing films in the growth temperature range of 250-300° C. The thermal ALD and p-CVD methods shown herein ensure that the high-temperature-induced roughening, which causes high surface resistances in MgB2 coatings grown by the mentioned conventional techniques, is avoided. The MgB2 and MgB2-containing films exhibit superconductive properties at above 20° K.
