Abstract: An objective for a projection exposure apparatus includes a metrology stage arranged on the frame of the objective. The objective includes at least one optical component, an objective mount for mounting the optical component, and a positioning device for holding at least one measuring device. The positioning device is connected to the objective mount and has at least one degree of freedom of displacement for displacing the measuring device.

Abstract: The invention relates to a process for determining at least one state variable from a model of an RTP system by means of at least one measurement signal measured on the RTP system—the measurement value—which has a dependency upon the state variable to be determined, and a measurement value forecast by means of the model—the forecast value—, whereby the measurement value and the forecast value respectively comprise components of a constant and a changeable portion, and whereby respectively at least the changeable portion is established, separated by a filter, so as to form a first difference between the changeable portion of the measurement value and the changeable portion of the measurement value forecast by the model, parameter adaptation of at least one model parameter by recirculation of the first difference in the model with the aim of adapting the model behavior to variable system parameters, forming of a second difference from the measurement value and the forecast value or from the measurement value ad

Abstract: The object of the disclosure is to measure temperature using pyrometers, in a simple and economic way, enabling precise temperature measurement, even for low temperatures. The disclosure presents an apparatus and method for thermally treating substrates, wherein the substrate is exposed to at least a first and at least a second radiation; the predetermined wavelengths of the first radiation are absorbed between the first radiation source and the substrate; a radiation from the substrate is measured in the predetermined wavelength using a radiation detector arranged on the same side as a second radiation source; the second radiation from the second radiation source is modulated and determined.
