As the integration density of semiconductor devices increases, it becomes extremely difficult to fabricate and monitor the quality of very thin insulating layers measuring less than 10 nm. The layer material generally used is silicon nitride which is suitable for a wide range of applications. Presently, there are no fast measuring methods for monitoring the quality of such thin layers during the production of semiconductor devices. The measuring method described below serves to determine the carbon concentration in thin silicon nitride layers.
