System for the radiation treatment of substrates
A system for the radiation treatment of substrates, which comprises, in a chamber above the substrate holders for fitting substrates to be treated, at least one radiation source, and wherein the chamber comprises means for maintaining a gas flow in the chamber with at least one gas inlet and at least one gas outlet, characterized in that the at least one gas inlet is disposed in the region of the substrate holders in such a way that gas flowing in through the at least one gas inlet first flows around the substrate holders prior to leaving the chamber again, either directly and/or after flowing around the at least one radiation source, through the gas outlet.
1. A system for the radiation treatment of substrates, comprising:
a chamber above at least one substrate holder for fitting substrates to be treated; and
at least one radiation source in the chamber, wherein the chamber maintains a gas flow in the chamber with at least one gas inlet and at least one gas outlet, with the at least one gas inlet disposed in a region of the substrate holders in such a way that gas flowing in through the at least one gas inlet first flows around the substrate holders prior to leaving the chamber again, either directly and/or after flowing around the at least one radiation source, through the at least one gas outlet, and indentations are provided at a lower edge of the chamber in such a way that the flow is reduced in a region of the indentations and, accordingly, the indentations act as dust collectors.
2. The system according to claim 1 , wherein the at least one gas outlet is provided in a region of the at least one radiation source in such a way that the gas, subsequent to flowing around the substrate holders, flows around the at least one radiation source before leaving the chamber via the at least one gas outlet.
3. The system according to claim 1 , wherein the at least one gas outlet is provided at a level between the at least one substrate holder and the at least one radiation source.
4. The system according to claim 3 , further comprising a second gas inlet in a region of the at least one radiation source in such that gas flowing in through the second gas inlet first flows around the at least one radiation source prior to encountering gas that flows from the substrate holders, and the gas flowing in through the second gas inlet flows out of the chamber together with the gas that flows from the substrate holders.
5. The system according to claim 1 , further comprising removable containers ae provided, at least partially, in the indentations.
