Angstrom Sun Technologies Inc developed TFProbe® Software Version 2.X for our Spectroscopic reflectometer, Microspectrophotometer and film thickness mapping tools. Major applications are for Thin Films, Spectroscopy and Digital Imaging. Both film thickness measurmeent and their optical constants are from data regression by fitting measured either reflection spectra or transmissiom spectra to ones with a defined layer stack, also called model. So acquring spectra is very basic function for the software. That is why some users simply use it to measure antireflection coating and/ filter's performance. TFProbe 2.x version software allows user to define up to 5 layers of coating on substrate. Each layer can be defined using their known optical NK table, or dispersion (to measure their refractive index N and extinction coefficient K), or mixture of two known components with effective media approximation method(EMA). In later case, the films's physical density or porosity can be determined.
Both advanced Levenberg–Marquardt (L-M) and fast Fourier transform (FFT) algorithms are implemented in TFProbe 2.x version software. In addition, search function, scale, dampling functions are also available, which provides practical solutions to many special applications. A time series data acqusition/analysis mode provides user for time controlling based measurement, such as kinetic research, real time monitoring on film growth, etching processing monitoring etc.
Built-in mapping pattern definition, 2D/3D mapped results presentation, loading the saved data for remodeling are available in this version software. Live video, capable to view and record the image to memorize the data acquired location is a desire for measurements on textured and patterned surfaces, like MEMS device, medical devices and many other types samples.
Angstrom Sun Technologies Inc has also successfully customized soultions for in-line applications, like CMP processing monitoring with uniquely developed large area Zone Average Model for non-planar production wafers. Our experience will help us to find suitable solution for your application too.
