摘要:
The invention relates to a device for depositing at least one especially thin layer onto at least one substrate (9). Said device comprises a process chamber (1, 20, 11, 11′, 40, 21), housed in a reactor housing (2) and comprising a movable susceptor (20) which carries the at least one substrate (9). A plurality of gas feed lines (24) run into said process chamber and feed different process gases which comprise coat-forming components. Said process gases can be fed to the process chamber in subsequent process steps, thereby depositing the coat-forming components onto the substrate (9). In order to increase the throughput of said method, the process chamber is provided with a plurality of separate deposition chambers (11, 11′) into which different gas feed lines (24, 24′) run, thereby feeding individual gas compositions. The substrate (9) can be fed to said chambers one after the other by moving the susceptor (20) and depositing different layers or layer components.

The invention relates to a method and to a device for treating semiconductor substrates. In conventional systems, the especially uncoated semiconductor substrates are fed to a treatment device through a charging sluice, said charging sluice adjoining a transfer chamber. A plurality of treatment chambers can be charged with the semiconductor substrates to be treated from said transfer chamber by first evacuating the transfer chamber and the treatment chamber and then opening the connecting door between the transfer chamber and the treatment chamber. The aim of the invention is to improve this system. To this end, at least one of the treatment chambers is operated at a low pressure or atmospheric pressure and the transfer chamber is flooded with an inert gas before the connecting door associated with the treatment chamber is opened, while a predetermined pressure difference between the transfer chamber and the treatment chamber is maintained.

The invention relates to a device and method for depositing one or more layers onto at least one substrate placed inside a reaction chamber. The layers are deposited while using a liquid or solid starting material for one of the reaction gases utilized, which are fed via a gas admission unit to the reaction chamber where they condense or epitaxially grow on the substrate. The gas admission unit comprises a multitude of buffer volumes in which the reaction gasses enter separate of one another, and exit through closely arranged outlet openings while also being spatially separate of one another. The temperature of reaction gases is moderated while passing through the gas admission unit.

In a method and an apparatus for converting a liquid flow into a gas flow, a liquid flow is introduced into an evaporation volume, the liquid flow is dispersed so as to enlarge the surface of the liquid, the dispersion being not caused by a change of pressure and taking place without admixture of a medium, and the evaporated liquid flow is conducted out of the evaporation volume.
