Abstract

In a process chamber (1), in which various processing steps in the manufacture of semiconductors can be carried out, there is arranged a rotationally drivable rotary head (3) which serves as a holder for a substantially disc-shaped object to be processed (W), e.g. for a wafer. Furthermore, at least one applicator (50, 51, 52, 53) is provided in the process chamber (1) for the provision of a medium which acts on the object to be processed (W). Means (4) are arranged radially around the rotary head (3) for the journalling and for the driving of the rotary head (3).
