    Abstract: What is described is a process and an installation for drying articles, in particular painted vehicle bodies, in which the articles are moved through a drying zone in which they are hardened in an inert-gas atmosphere. Inert gas is taken from the drying zone constantly or intermittently and is first of all conducted along a first face which is at a first temperature at which higher-boiling contaminants condense out. The condensate that forms in the process is discharged. After that, the inert gas which has been pre-cleaned in this way is conducted along at least one second face which is at a lower temperature than the first face. Lower-boiling contaminants are precipitated at this point. These condensates, too, are then discharged. This process and installation work more favourably, energy-wise, and with higher cleaning efficiency than known processes and installations of a similar type.

  • Patent number: 7146744
    Abstract: The present invention provides method and apparatus for surface treatment which, when employed in process steps of manufacturing semiconductor devices, can result in the final products having enhanced reliability. According to the surface processing method, an obeject to be processed W is introduced in a processing vessel 10, which is then supplied with ClF3 gas serving as cleaning gas from a supply unit 26. The ClF3 gas is bound to the surface of the object to be processed W, and although the supply of the gas to the processing vessel is interrupted, the ClF3 gas bound to the surface of the object to be processed W serves to clean the surface of the object to be processed. Next, reducing gas is introduced into the processing vessel W to remove chlorine from the object to be processed W, the chlorine being derived from the ClF3 gas. After that, the introduction of the reducing gas is interrupted, and the cleaned object to be processed W is exported from the processing vessel 10.
