CVD REACTOR COMPRISING A SUBSTRATE HOLDER ROTATABLY MOUNTED AND DRIVEN BY A GAS FLOW

摘要

The invention relates to a device for depositing layers, particularly crystalline layers, onto substrates. Said device comprises a process chamber (2) arranged in a reactor housing (1) where the floor (3) thereof, comprises at least one substrate holder (6) which is rotatably driven by a gas flow flowing in a feed pipe (5) associated with said floor. Said substrate holder is disposed in a bearing cavity (4) on a gas cushion and held in place thereby. The aim of the invention is to technologically improve the design of a substrate holder which is rotatably mounted in a gas flow, particularly in a linear cross-flowing process chamber. Said bearing cavity (4) is associated with a tray-shaped element (8) arranged below the outflow (7) of the feed pipe (5).
