Latest Patents

One of Medvedev's latest patents is titled "Horizontal development bias in negative tone development of photoresist." This patent focuses on techniques for resist simulation in lithography. The disclosed methods involve determining local minimal light intensity values for various sample points in boundary regions of an aerial image of a feature to be printed on a resist coating. These values represent the minimum light intensity for areas surrounding the sample points. Based on these local minimal light intensity values, horizontal development bias values are determined, which are crucial for accurately predicting resist contour data of the feature.

Another significant patent by Medvedev is "Grid-based resist simulation." This invention predicts how a wafer coated with one or more resist layers will develop when exposed to a mask pattern. The process involves calculating image intensity values at a grid of points on the wafer and analyzing these points with a resist simulator to produce a resist surface function. The threshold contour of this function defines how the mask pattern will print on the wafer.
