Abstract:
A device for depositing crystalline layers on a crystalline substrate, comprising a process chamber disposed in a reactor housing, the process chamber including:a base having a feed line associated with the base for providing a gas stream through the feed line, the feed line having an outlet opening; a tray disposed on the base, an upper surface of the tray including a bearing recess and a lower surface of the tray including an annular bead which defines a sealed volume in fluid communication with the said feed line; a substrate holder at least partially received in the bearing recess of the tray, the substrate holder being rotatable by the gas stream delivered through the outlet opening of the feed line and exiting about the bearing recess of the tray which generates a gas cushion to the substrate holder.
