  • Patent number: 9805993
    Abstract: An apparatus and a method for determining the temperature of a substrate, in particular of a semiconductor substrate during the heating thereof by means of at least one first radiation source are disclosed. A determination of the temperature is based on detecting first and second radiations, each comprising radiation emitted by the substrate due to its own temperature and radiation emitted by the first radiation, which is reflected at the substrate and at least one of a drive power of the first radiation source and the radiation intensity of the first radiation source.

  • Publication number: 20160217982
    Abstract: Disclosed are a method and an apparatus for the detection of a plasma in a process chamber for the treatment of substrates. In the method, the pressure within the chamber is measured over a period of time using a pressure sensor, a sudden change in pressure is detected and an ignition or extinguishing of a plasma determined at least by means of the pressure change. The apparatus comprises a process chamber, for receiving at least one substrate, with at least one plasma generator, at least one pressure sensor which is situated so as to detect the pressure within the process chamber and output an output signal corresponding to the pressure, and at least one evaluation unit. The evaluation unit is capable of monitoring over a period of time an output signal from the pressure sensor and, on the basis of at least one sudden change in the output signal of the pressure sensor, of determining an ignition and/or an extinguishing of a plasma.

  • Patent number: 9252011
    Abstract: A method for forming an oxide layer on a substrate is described, wherein a plasma is generated adjacent to at least one surface of the substrate by means of microwaves from a gas containing oxygen, wherein the microwaves are coupled into the gas by a magnetron via at least one microwave rod, which is arranged opposite to the substrate and comprises an outer conductor and an inner conductor. During the formation of the oxide layer, the mean microwave power density is set to P=0.8-10 W/cm2, the plasma duration is set to t=0.1 to 600 s, the pressure is set to p=2.67-266.64 Pa (20 to 2000 mTorr) and a distance between substrate surface and microwave rod is set to d=5-120 mm. The above and potentially further process conditions are matched to each other such that the substrate is held at a temperature below 200° C. and an oxide growth is induced on the surface of the substrate facing the plasma.

  • Patent number: 6809011
    Abstract: The invention relates to a method for generating defect profiles in a crystal or crystalline structure of a substrate, preferably a semiconductor, during a thermal treatment in a process chamber. According to the inventive method, a concentration and/or a density distribution of defects is controlled with at least one reactive component each depending on at least two process gases that differ in their composition. At least two of the process gases independently act upon at least two different surfaces of the substrate.
