Abstract: A device for processing wafer-shaped articles comprises a closed process chamber that provides a gas-tight enclosure. A rotary chuck is located within the closed process chamber. A heater is positioned relative to the chuck so as to heat a wafer shaped article held on the chuck from one side only and without contacting the wafer shaped article. The heater emits radiation having a maximum intensity in a wavelength range from 390 nm to 550 nm. At least one first liquid dispenser is positioned relative to the chuck so as to dispense a process liquid onto a side of a wafer shaped article that is opposite the side of the wafer-shaped article facing the heater.

Abstract: The present invention relates to a method of treating wafers comprising at least one surface layer of silicon-germanium (SiGe) and a layer of strained silicon (sSi) in contact with the SiGe layer, the sSi layer being exposed by etching of the SiGe layer, the method comprising the steps of: (a) a first selective etch of the SiGe layer, optionally followed by an oxidative cleaning step; (b) a rinsing step using deionized water; (c) drying; and (d) a second selective etch step. The present invention relates to a wafer comprising at least one surface layer of strained silicon (sSi), the at least one surface layer of sSi having a thickness of at least 5 nm and at most 100 ?m and having at most 200 defects per wafer.
