For the analysis of thin films, with high aspect ratio (HAR) structures, time-of-flight secondary ion mass spectrometry (ToF-SIMS) overcomes several challenges in comparison to other frequently used techniques such as electron microscopy. The research presented herein focuses on two different kinds of HAR structures that represent different semiconductor technologies. In the first study, ToF-SIMS is used to illustrate cobalt seed layer corrosion by the copper electrolyte within the large through-silicon-vias (TSVs) before and after copper electroplating. However, due to the sample’s surface topography, ToF-SIMS analysis proved to be difficult due to the geometrical shadowing effects. Henceforth, in the second study, we introduce a new test platform to eliminate the difficulties with the HAR structures, and again, use ToF-SIMS for elemental analysis. We use data image slicing of 3D ToF-SIMS analysis combined with lateral HAR test chips (PillarHall™) to study the uniformity of silicon dopant concentration in atomic layer deposited (ALD) HfO2 thin films.

ABSTRACTSecondary ion mass spectrometry (SIMS) and Rutherford Backscattering Spectrometry (RBS) techniques were used to determine InxGa1-xN and AlxGa1-xN compositions. While RBS is generally considered a quantitative technique for compositional analysis, SIMS has not been. We have applied a new analytical technique, which reduces the matrix effect in SIMS analysis, to accurately determine stoichiometry. The composition of InxGa1-xN (AlxGa1-xN) in the multiple layers and quantum well of the LED can be measured by SIMS, but is inaccessible to RBS.

Perovskite potassium niobate (KNbO3) possesses good electrooptic properties for modulated channel waveguide applications, Epitaxial KNbO3 thin films were deposited onto (100) MgO substrates using an ion beam sputtering technique equipped with a novel computer-controlled rotating target holder , Conventional transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM) were employed to perform defect structure and microstructure analysis. Special TEM sample preparation procedures have been developed, which will be reported elsewhere, Tetrahedral twin particles (TTP's) were observed in the epitaxial KNbO3 thin films. Since, the orientation difference between the TTP's and the matrix may affect the polarization switching properties, it is essential to understand their origin and eliminate them if possible.A selected area diffraction pattern of a KNbO3 thin film taken along the substrate (012) (figure 1) reveals twin and double diffraction spots. The mirror planes are determined to be of the {211} family. Figure 2(a) shows the electron diffraction pattern taken along the substrate (100). Twin spots coincide with some of the matrix spots indicating that the twin also maintains an epitaxial relationship with the MgO substrate. The orientation relationship between the twins and the matrix is [221]twin//[100]matrix.
