To improve the utility and ultimate dissemination of our published TPL software tool, we have been developing a framework for which to incorporate (experimental) process variability in our simulation model in order to obtain insight into the repeatability of the TPL process. Our initial approach uses 3D geometric measurements of fabricated structures/features. The tool will provide:

1.Spatial distributions of geometric features. (a)Height (b)Radius (c)Volume

2.Geometric deviation from the designed shape.

3.Summary of geometric features and errors
