Metric Options: CountsSelecting 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.

Article Description
Chemical mechanical planarization (CMP) is the primary method of wafer-scale planarization used in the manufacture of advanced integrated circuits. Preston's model, which was introduced in the 1920s for glass polishing, is an important component of much of the recently published work on CMP modeling. As applied, Prestonian models are effective in describing the average behavior of a process but are ineffective in providing fundamental understanding and locally relevant information regarding a chosen process. To date, there are still very few quantitative wafer-scale CMP removal rate and uniformity models. In this work, a locally relevant expression for material removal rate based on Preston's equation is presented. It incorporates localized kinematics and stress calculations. The model predictions are compared to experimental results for silicon dioxide polishing on a dual-axis CMP platform. © 2003 The Electrochemical Society. All rights reserved.
