Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

New Findings from Chinese Academy of Sciences Describe Advances in Semiconductor Processing (Effect of Ion Assistance On Silicon Nitride Films Deposited By Reactive Magnetron Sputtering)
2023 JUN 26 (NewsRx) -- By a News Reporter-Staff News Editor at Electronics Daily -- Investigators discuss new findings in Materials Science - Semiconductor Processing.
Article Description
Silicon nitride films were deposited by reactive magnetron sputtering, during which ion assistance was introduced. The results showed that the optical properties and composition were significantly affected by ion assistance. The refractive index was decreased from 2.87 to 2.17, and the extinction coefficient was decreased from 0.1535 to 0.0031 (@492 nm). The nitrogen-to-silicon ratio was increased from 0.612 to 0.955 by ion assistance, shifting from silicon-rich to near-stoichiometric. Not only that, the ion-assisted film featured lower roughness and less impurity. As the ion source power increased, the Raman peaks of silicon and silicon oxide decreased as well. In this work, ion assistance exhibits a considerable effect on silicon nitride films, which has potential applications in the processing of silicon nitride films and other semiconductor thin films.
