    Abstract: Disclosed is a method involving repeatedly measuring a pressure within a flow of processing gas that is provided in a semiconductor processing apparatus for treatment of a semiconductor substrate, such as a semiconductor wafer. The flow of processing gas is made to extend between a surface of the substrate and a surface of a processing body. From the pressure measurements the occurrence of an event that is related to a variation in the position of the substrate's surface relative to the surface of the processing body is determined.

    Abstract: The publication discloses a method for determining a temperature of a substrate, comprising: providing a gas channel that is confined by at least one wall having a certain wall temperature; providing a substrate in said gas channel, proximate to the at least one wall, such that a gap exists between a surface of the substrate and the at least one wall; providing a gas flow with a certain mass flow rate through said gas channel, which gas flow extends at least partially through said gap; determining a pressure drop in the gas flow along the gas channel; and deriving from said pressure drop the temperature of said substrate using a pre-determined relation between the pressure drop along the gas channel, the wall temperature and the temperature of the substrate, at said mass flow rate. Also disclosed is a device for implementing the disclosed method.
