  • Publication number: 20100003405
    Abstract: The invention relates to a method for coating one or more substrates with a layer the components of which are passed into a process chamber (7) in the form or at least two gases by means of a gas inlet element. The gases are introduced into respective chambers (1, 2) of the gas inlet element that arranged one on top of the other and enter the process chamber (7) through gas outlet openings (3, 4) leading to the process chamber (7). The aim of the invention is to improve the aforementioned method or aforementioned device for producing homogeneous layers. For this purpose, each of the two chambers is subdivided into two compartments (1a, 1b; 2a, 2b) each which are arranged one on top of the other to be substantially congruent.

  • Publication number: 20080308040
    Abstract: The invention relates to a device for depositing at least one layer on a substrate by means of a process gas which is introduced through a flow channel (4), extending in a vertical direction, of a gas inlet member (3), fixed in place with respect to a reactor housing, into a process chamber (1), extending in a horizontal direction, wherein the process gas leaves a gas outlet opening of a portion of the gas inlet member (3), protruding into the centre of the rotationally symmetrical process chamber (1), and flows in a radially outward direction via a base (8?) of the process chamber (1), extending in a horizontal direction and rotating about the centre, on which base the substrate lies. In order to improve the gas flow directly above the base of the process chamber, it is proposed that the front (3?) of the gas inlet member (3) protrudes into a pot-like recess (23) and an end portion (6?) of a gas deflecting face (6) is flush with the base (8?).

  • Publication number: 20080092817
    Abstract: The invention concerns a deposition device in particular of crystalline coatings on at least one substrate in particular crystalline. Said device comprises a treatment chamber (5) consisting of a number of wall elements (1, 2, 3, 4), said wall elements (1, 2, 3, 4) being electroconductive and placed end-to-end, thus forming contacts (2?, 2?, 3?, 3?); a reactor housing (6) enclosing the wall elements (1, 2, 3, 4) of the treatment chamber and made of a non-electroconductive material and a RF-heated coil surrounding the wall elements (1, 2, 3, 4) of the treatment chamber. The invention is characterized in that a massive single-piece shield heating pipe (8) is implanted between the reactor housing (6) and the walls (1, 2, 3, 4) of the treatment chamber. The material of said pipe is electroconductive so that it is heated by the eddy currents induced therein by the RF field generated by the RF coil and so that it absorbs considerably the RF field and heats the walls (1, 2, 3, 4) of the treatment chamber.

  • Publication number: 20070074661
    Abstract: The invention relates to a CVD reactor which comprises a process chamber, disposed inside a reactor housing and having process chamber walls, a process chamber bottom and a process chamber ceiling spaced apart by a distance from the process chamber bottom. The reactor housing comprises at least one reactor wall which can be slightly elastically deformed when the pressure within the reactor housing changes. Said reactor wall is provided with an especially center opening through which a functional element projects. Said functional element is firmly linked via a first section with a process chamber wall and has a second section that is located outside the reactor housing. In order to increase the reproducibility of results, the functional element is linked with the reactor wall so as to elastically yield.

  • Patent number: 7147718
    Abstract: The invention relates to a device and method for the deposition of in particular, crystalline layers on one or several, in particular, equally crystalline substrates in a process chamber, by means of reaction gases which are fed to the process chamber where they react pyrolytically. The process chamber has a first wall and a second wall, lying opposite the first. The first wall is provided with at least one heated substrate holder, to which at least one reaction gas is led by means of a gas inlet device. According to the invention, a premature decomposition of source gases and a local oversaturation of the gas flow with decomposition products may be avoided, whereby the gas inlet device is liquid cooled.

  • Patent number: 6905548
    Abstract: The invention relates to a device for the deposition of in particular, crystalline layers on one or several, in particular, equally crystalline substrates, comprising a process chamber, arranged in a reactor housing, which may be charged with the substrates from above, by a reactor housing opening which may be sealed by a cover. The reactor housing opening opens out into a glove box, in particular flushed with highly pure gas and connects electricity, liquid or gas supply lines to the cover. According to the invention, the connection of supply lines for electricity, fluid or gas sources arranged outside the glove box to the cover of the reactor housing arranged within the glove box may be improved, whereby the electricity, fluid or gas supply lines run freely, from outside the glove box, through a flexible tube which is sealed atone end to a flange arrangement rigidly fixed to the cover and sealed at the other end to an opening in the glove box wall.
