20210307880 · 2021-10-07 · ·

The present invention relates to an abutment of a dental implant system for connecting a dental implant and a suprastructure, said abutment comprising an abutment basic body extending from an apical end to a coronal end arranged opposite to the apical end. The abutment basic body comprises a dental implant connecting portion facing the apical end and adapted to fit with a corresponding abutment connecting portion of the dental implant and/or an intermediate part to be directly or indirectly connected with the dental implant. It further comprises a support portion facing the coronal end and designed such to allow the suprastructure to be mounted directly or indirectly. According to the invention, the abutment further comprises nanostructures formed on at least a portion of the outer surface of the abutment basic body, said nanostructures extending in at least two dimensions to 200 nm at most.

SELECTIVE DEPOSITION OF SILICON OXIDE ON DIELECTRIC SURFACES RELATIVE TO METAL SURFACES

Methods for selective deposition of silicon oxide films on dielectric surfaces relative to metal surfaces are provided. A metal surface of a substrate may be selectively passivated relative to the dielectric surface, such as with a polyimide layer or thiol SAM. Silicon oxide is selectively deposited on the dielectric surface relative to the passivated metal surface by contacting the dielectric surface with a metal catalyst and a silicon precursor comprising a silanol.

Processing System and Platform for Wet Atomic Layer Etching Using Self-Limiting and Solubility-Limited Reactions
20200161148 · 2020-05-21 ·

A processing system and platform for improving both the microscopic and macroscopic uniformity of materials during etching is disclosed herein. These improvements may be accomplished through the formation and dissolution of thin, self-limiting layers on the material surface by the use of wet atomic layer etching (ALE) techniques. For etching of polycrystalline materials, these self-limiting reactions can be used to prevent this roughening of the surface during etching. Thus, as disclosed herein, a wet ALE process uses sequential, self-limiting reactions to first modify the surface layer of a material and then selectively remove the modified layer.
