A method for forming an oxide layer includes forming a protective interlayer oxide on sidewalls of a trench formed on a substrate, forming a silicon nitride layer on the protective interlayer oxide, by a plasma-enhanced atomic layer deposition (PE ALD) process utilizing nitrogen-containing process gas, the silicon nitride layer having a concentration gradient of nitrogen varying from high concentration away from the protective interlayer oxide to low concentration near the protective interlayer oxide, and performing a conversion process to oxidize the formed silicon nitride layer to at least partially convert the formed silicon nitride layer to a silicon oxide layer.

Plasma showerheads with improved gas uniformity, and a plasma showerhead with angled gas nozzles are disclosed. Also disclosed are gas nozzles having a vertical offset angle and/or a directional offset angle. None of the gas channels and/or the gas nozzles intersect with the plasma regions of the showerhead.

An online system tracks stores information identifying content provided by third party systems and accessed by online system users as well as interactions with advertisements performed by online system users. When the online system identifies an opportunity to present an advertisement to a viewing user, the online system identifies content from third party systems accessed by the viewing user and content from third party systems accessed by additional online system users who interacted with advertisements. A score is computed for various advertisements based at least in part on correlations between content from third party systems accessed by the viewing user and content from third party systems accessed by additional online system users who interacted with advertisements. The online system selects candidate advertisements to evaluate for presentation to the viewing user based on the scores.

Selecting content for presentation to online system users based on correlations between content accessed by users via third party systems and interactions with online system content

An online system receives multiple candidate components for including in content items to be presented to online system users. Upon identifying an opportunity to present content to a subject user of the online system, the online system dynamically generates an optimal content item for presentation to the subject user that includes one or more candidate components. Candidate components included in the optimal content item are selected by predicting an affinity of the subject user for each candidate component. The affinity of the subject user for a candidate component may be predicted using a machine-learned model that is trained using historical performance information about content items including the candidate component that were presented to viewing users of the online system having at least a threshold measure of similarity to the subject user. Components of content items used to train the model may be selected using a heuristic (e.g., Thompson sampling).

A process for separating components or a fluid mixture using membranes comprising a selective layer made from copolymers of an amorphous per fluorinated dioxolane and a fluorovinyl monomer. The resulting membranes have superior selectivity performance for certain fluid components of interest while maintaining fast permeance compared to membranes prepared using conventional perfluoropolymers, such as Teflon&#xae; AF, Hyflon&#xae; AD, and Cytop&#xae;.

Fluid separation processes using membranes based on fluorinated and perfluorinated polymers

A process for separating components of a gas mixture using gas-separation copolymer membranes. These membranes use a selective layer made from copolymers of partially fluorinated or perfluorinated dioxolane monomers and a second monomer, such as dioxane or a partially fluorinated dioxolane. The resulting membranes have superior selectivity performance for gas pairs of interest while maintaining fast gas permeance compared to membranes prepared using conventional perfluoropolymers, such as Teflon&#xae; AF, Hyflon&#xae; AD, and Cytop&#xae;.
