摘要:
Method and device for the heat treatment of flat substrates, wherein the substrates are positioned in the vicinity of a heated, essentially flat furnace body extending over the surface of the substrate. In order to provide a reproducible treatment when treating a number of substrates successively, the temperature of the furnace body is measured so close to the surface adjacent to the substrate that the withdrawal of heat from the furnace body by the substrate can be detected. The introduction of each substrate takes place at a point in time when the temperature measured in this way is, within certain limits, equal to a desired initial treatment temperature T trig .

摘要:
An apparatus for treating a wafer manufactured from semiconducting material, the apparatus comprising a first and a second housing part arranged for movement away from and towards each other, the two housing parts bounding a treatment chamber, while around the treatment chamber there is provided a first groove connected to gas discharge means, while in at least one of the two boundary surfaces there is provided a second groove connected to gas feed means, the first groove being located radially within the second groove, and, in use, the pressure created by the gas feed means being such that from the second groove, gas flows both in radial inward and in radial outward direction in the gap between the first and the second boundary surface.
