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.

Article Description
Resist filling behavior is crucial to the quality of final imprinted patterns in microimprint lithography (MIL). This article investigates the velocity field of the resist in microimprint lithography through numerical simulations and visualization experiments. To achieve the microscale velocity field of resist, a numerical model based on the computational fluid dynamics was built to predict the resist filling behavior, and the surface tension and contact angle were considered in this model. Meanwhile, a 3-D defocusing digital particle image velocimetry (DDPIV) was established. The spatial coordinates of the fluorescent tracer particles were derived from their DDPIV images. Time-resolved 3-D particle field inside the resist was obtained with the spatial coordinates. Particle tracking velocimetry was utilized to derive the velocity field from the particles spatial position in the imprinting process. The investigation of the velocity field, including the horizontal and vertical velocity history, was carried out to directly describe the filling mode of the resist and hence determining the resist filling mechanism. The results of the visualization experiments and the numerical simulations were compared to obtain an in-depth understanding of the resist flow in MIL. © 2013 American Vacuum Society.
