Definitions
- the invention relates to a device for injecting gas into a reactor, in particular an installation for rapid thermal treatment RTP or chemical vapor deposition CVD, comprising a reaction chamber with sealed enclosure provided with a porthole in transparent material permitting electromagnetic radiation of the infrared and / or ultraviolet IR type emitted by heating lamps, the reactive gas being injected by spraying means onto the surface of a substrate subjected to said radiation.
- UV and / or IR lamps arranged opposite the substrate in a compartment having a reflector and separated from the enclosure of the reaction chamber by a quartz window.
- the reactive gas injection system which is located between the UV and or IR lamps and the substrate must make it possible to obtain a uniform spraying of the reactive gases on the surface of the substrate without masking the electromagnetic radiation emitted by the lamps.
- the object of the invention is to provide a multi-zone gas injection device for a single port reactor, avoiding any effect of masking the radiation of the lamps.
- the device according to the invention is characterized in that it comprises: a plurality of channels arranged radially at mid-height in the same horizontal plane of the body of the window by being placed in communication with at least one peripheral supply casing connected to an external gas circuit, - and blind holes drilled vertically in the porthole from the underside oriented towards the side of the reaction chamber to open into the channels.
- the channels are distributed in the window in a star-shaped diametrical arrangement.
- the blind holes may have cylindrical or conical sections of the same dimensions, or increasing sections towards the center of the window.
- the metal enclosure comprises at least one cavity in which a heat transfer fluid circulates coming from an external cooling circuit.
- the undrilled side of the window can be separated from the envelope of the lamps by an interval filled with a coolant which is transparent to the wavelength of electromagnetic radiation.
- an undrilled auxiliary porthole is arranged between the gap and the envelope of the lamps.
- FIG. 1 is a schematic sectional view of the reactor equipped with the gas injection device according to the invention
- - Figure 2a shows a bottom view of the porthole drilled in Figure 1;
- FIG. 2b is an identical view to Figure 2 of an alternative embodiment
- FIG. 3 is an identical view of the reactor of Figure 1 with two stages of intersecting lamps; - Figures 4 to 6 show three other alternative embodiments of the reactor.
- an RTP or CVD reactor designated by the general reference 10, includes a reaction chamber 12 associated with electromagnetic radiation heating lamps 14 of the infrared IR, and / or U V ultraviolet type.
- the reaction chamber 12 is provided with a sealed enclosure 16 provided with a one-piece porthole 18, which is made of a transparent material, for example quartz, allowing the light radiation from the lamps to pass through.
- the lamps 14 are housed opposite the substrate 20 in an envelope 22 fitted on its internal wall with a reflector 24 to channel the light radiation through the window 18.
- the enclosure 16 of the reaction chamber 12 is made of stainless steel or aluminum, with a cooled or thermalized wall (up to 300 ° C.), comprising a base 26 surmounted by a cover 28 with interposition of the porthole 18 piece.
- An external pumping system 30 is connected to an evacuation orifice 32 of the base 26 so as to work under atmospheric pressure or lower the internal pressure of the reaction chamber 12 to secondary voids.
- a flow of reactive gas is introduced from an external gas circuit 34 into the reaction chamber 12 through the porthole 18, to cause chemical reactions modifying the physico-chemical properties of the material arranged on the substrate 20, or producing a deposition of the material in the form of a layer on said substrate 20.
- seals 36 The sealing of the cylindrical porthole 18 relative to the base 26 and the cover 28 is ensured by seals 36, with the formation of at least one peripheral casing 38 extending in the vicinity of the edge of the porthole 18.
- Each casing 38 is connected to the external gas circuit 34 by a pipe 40 provided with a valve
- the one-piece porthole 18 made of quartz has a first function for sealingly separating the reaction chamber 12 and the casing 22 of the lamps 14, and a second function for uniform distribution of the reactive gas over the surface of the substrate 20.
- a plurality of channels 44 are machined for this purpose horizontally at mid-height in the body of the window 18, and placed in communication with the peripheral casing or casings 38.
- Cylindrical blind holes 46 are drilled vertically in the porthole 18 from the underside to open into the channels 44, so as to make the reaction chamber 12 communicate with the external gas circuit 34.
- FIG. 2a shows a view from below of the porthole 18 illustrating by transparency the diametrical star distribution of the horizontal channels 44, and the vertical holes 46 staggered at regular intervals along these channels.
- additional channels 48 are inserted radially between the successive channels 44 to increase the total number of holes 46.
- the use of several peripheral casings 38 allows a uniform supply of the horizontal channels 44, 48 inside the porthole 18.
- the quantity of gas injected by the vertical holes 46 tends to decrease during progression of the gas towards the center of the substrate 20. To remedy this, it suffices to gradually increase the diameter of the holes 46 in the direction of the center to obtain a uniform distribution of the gas projected onto the substrate 20.
- the base 26 and the cover 28 of the enclosure 16 of FIGS. 1 and 3 are maintained at a predetermined temperature by means of a heat transfer fluid circulating in at least one annular cavity 52, 54 in connection with a cooling or cooling circuit. outdoor thermal 56.
- a second porthole 58 is added, not pierced under the envelope 22 of the lamps 14, separating it from the porthole 18 pierced by an interval 60 in which a heat transfer fluid circulates.
- the latter is transparent to the wavelength of the IR radiation from the lamps 14, and allows efficient cooling by keeping the windows 18, 58 clean.
- a second envelope 22a with lamps 14a is arranged opposite the first envelope 22, so as to irradiate the two faces of the substrate 20 inside the reaction chamber 12.
- the window 58 attached to the second envelope 22a is not pierced, and the lamps 14, 14a can have either the same type of IR or UV radiation, or different radiation.
- the portholes 18, 18a pierced with the two opposite envelopes 22, 22a are associated with lamps 14, 14a having the same radiation, authorizing the simultaneous implementation of the same process on the two faces of the substrate 20
- the evacuation of the reaction chamber 12 is effected symmetrically by means of a double exhaust circuit 60 in connection with the pumping system 30.
- the multi-zone gas injection device according to FIGS. 1 to 6 can be used in numerous deposition applications in a CVD reactor placed under reduced or atmospheric pressure. The deposition can be carried out by heating with IR lamps in an RT-CVD rapid heat treatment reactor.
- the deposition can also be assisted by means of ultraviolet radiation emitted by UV lamps, in order to reduce the heating temperature of the substrate 20.
- UV lamps can be conventional (xenon, mercury, deuterium), or of the type excimers, consisting of: Ar 2 *, Kr 2 *, Xe 2 * , F 2 * , Cl 2 *, Br 2 * , l 2 * ArF *, ArCI * , KrCI * .
