A complication and barrier to wider uptake of SIMS, especially for organic materials, is the complexity of the mass spectrum. The G-SIMS method (from gentle-SIMS) was developed to simplify the spectra and provide direct interpretation based on the physics and chemistry of the SIMS process rather than on statistical analysis techniques such as principal component analysis or library matching methods.

Introduction

The decrease of dimensions and increasing complexity of thin-film and multilayer structures require the application of methods that provide information down to the nanometre scale. The quantification of nanostructures and surface layers with high sensitivity is often of crucial importance in monitoring product quality. Sensitive elemental analysis, together with a quantitative chemical analysis, is a prerequisite for the preparation of thin-layer structures of good quality.

Introduction

Since the interaction between solid materials and their surrounding media, whether gaseous or liquid, occurs at the surface, analytical techniques capable of providing information from the interaction region are fundamental in understanding the processes that are occurring. X-ray Photoelectron Spectroscopy (XPS) is one such technique, and is capable of analysing both conducting and insulating materials.
