APPLICATION OF GLOW-DISCHARGE OPTICAL-EMISSION SPECTROSCOPY TO STUDY SEMICONDUCTORS AND SEMICONDUCTOR-DEVICES

This letter introduces glow discharge optical emission spectroscopy for the study of semiconductors and semiconductor devices. It has been demonstrated that, by analysing simple Si-based devices, this technique is suitable for detecting impurity trace elements down to parts per million levels. It has also been shown that this is a fast and economical technique for depth profiling of semiconductor materials and device structures. The major advantages of this method are the low cost, speed and simplicity of analysis.
