Beschreibung
Zusammenfassung:	The plasma-enhanced chemical vapour deposition (PECVD) apparatus comprises a tubular chamber (100) configured for a wafer boat (10) with substrates. The PECVD apparatus further comprises heating means (110) arranged at an outside of the chamber and configured for emitting heat by means of radiation, and a controller for controlling a state inside the chamber (100), including temperature and composition. Herein, the heating means (110) are configured for the provision of radiation according to a radially varying profile within the chamber, which radial heating profile comprises a first radial zone (I) and a second radial zone (II), and wherein a heat flux (FI) in the first radial zone (I) is higher than the heat flux (FII) in the second radial zone.
