Organosilicon plasma investigated by mass spectrometry

This bachelor thesis deals with plasma-enhanced chemical vapor deposition (PECVD) and the use of mass spectrometry to monitor the processes in plasma during the deposition of thin film. Tetravinylsilane plasma was used in the process of forming a thin film on the silicon wafer. The background of the spectrometer, the residual gases in the plasma reactor at basic pressure were characterized and the plasma polymerization process was monitored. This process was monitored with increasing effective power (2-150 W). The obtained mass spectra were assigned and described in detail
