Latest Patents

Chuang holds a patent for a method of monitoring at least one of an overlay or an alignment between layers of a semiconductor substrate. The patent describes a scanning probe microscopy system and a computer program that facilitates this monitoring. The method involves scanning the substrate surface using a probe tip to obtain measurements of the topography of the first and second layers in at least one scanning direction. A pattern template is generated and matched with the topography of the first layer to determine a first candidate pattern. This first candidate pattern is then matched with the measured second topography to obtain a second candidate pattern, which represents the measured topography of the second layer. Feature characteristics of device features are determined from both candidate patterns, which are used to calculate one or more overlay or alignment parameters.
