Definitions
- the invention relates to a method for depositing compounds on a substrate by means of metal-organic gas phase deposition.
- MOCVD metal organic chemical vapor deposition
- components e.g. Lasers, high-speed transistors for cell phones or light emitting diodes can be used.
- these structures do not consist of only one, but of two or more elements. They are therefore also referred to as compound semiconductors.
- the organometallic gas phase deposition takes place in a so-called MOCVD system.
- the MOCVD system can be used to deposit nitride layers that consist of two elements, such as GaN, InN or AlN, or of several elements, such as GalnN or AlGaN. These connections are referred to as binary or tern re systems.
- nitride compounds sapphire (Al 2 0 3 ) or silicon carbide (SiC) or silicon, which have similar crystal properties to the nitrides, are used as substrates.
- the Group III nitrides through their representatives, span a semiconductor system with a direct band gap of 1.9 eV for the InN up to 6.2 eV for the AlN. These nitride layers are economically very important, since they can emit the blue part of the visible spectrum by electrical excitation and can therefore be used to implement optoelectronic components in the corresponding energy range.
- An example of this is pn light-emitting diodes based on GaN.
- Gaseous compounds of gallium, indium or aluminum and NH 3 as a so-called precursor are required for the metal-organic gas phase deposition of nitride layers.
- an organometallic compound for example trimethylgallium (TMG)
- TMG trimethylgallium
- the precursors are introduced into a reaction space of the plant by means of a carrier gas, for example hydrogen.
- a carrier gas for example hydrogen.
- the substrate a single-crystal, very thin disk (afer) that is heated.
- the wafer is rotatably mounted on a so-called susceptor in order to achieve a uniform distribution of temperature and precursor in the gas phase over the substrate.
- the susceptor and the substrate are heated via infrared radiators or high-frequency heating.
- the temperature on the substrate ranges up to approx. 1500 ° C, depending on which material system is being deposited. This area is also known as the hot zone.
- the precursors are implemented for deposition on the substrate. This happens in part in the gas phase due to the heat emanating from the substrate or through collisions with the molecules of the carrier gas.
- the molecule fragments sit on the substrate Surface.
- the original precursor compounds decompose and react again depending on the starting materials used, for example to GaN, InN or A1N.
- a new layer of GaN, InN or AlN grows on the wafer atom by layer.
- the residues of the starting molecules for example methyl groups from the TMG and hydrogen, combine to form methane. Molecules and molecular fragments that are not separated detach from the surface, are captured by the carrier gas stream like the methane and are flushed out of the MOCVD system into a gas cleaning system, the so-called scrubber.
- MOCVD systems have two gas inlets and options for dividing the gas flows to be introduced, since immediate mixing within the system is often undesirable because of the formation of acid-base adducts.
- a divider plate is arranged behind the gas inlets of the system in such a way that the MOCVD system is compartmentalized into an upper and a lower space.
- Gas collecting pipes are arranged outside the system and lead to the storage containers. The raw materials, ie metal organics on the one hand and Group V or Group VI compounds on the other hand, are stored in these storage containers.
- the precursors are thus Carrier gases (H 2 , N 2 , argon) each separately introduced into the system.
- the gas flows are only mixed in the hot zone of the plant.
- the carrier gas / NH 3 mixture group V compound
- group V compound is, according to the state of the art, introduced closer to the growth surface on the substrate than viewed locally the carrier gas / metal organic mixture. The consequence of this is that nitrogen is released from ammonia by the hot surface of the substrate and is available for the reaction on the substrate. This procedure is also used for the deposition of other compounds.
- the nitrides formed quickly deposit as parasitic deposits on the hot walls of the system.
- the nature and the thickness of the depositions change in the course of the procedure.
- the depositions change the growth on the substrate by catalytic decomposition of the starting compounds and cause depletion in the gas phase. Since the deposited compounds are colored dark, this affects the gas phase and surface temperatures above the substrate.
- the nitride layers can therefore not be reproducibly deposited on the substrate.
- the parasitic deposition also peels off after a short time.
- the particles fall from components of the system covered with parasitic deposition onto the substrate or the sample and adversely affect the properties of the layer (s) applied there.
- the components of the installation which are covered with parasitic deposition and which are connected to the substrate could be exchanged or cleaned as soon as a critical parasitic deposition has been deposited there.
- the object of the invention is to provide a method for the deposition of compounds on a substrate by means of organometallic gas phase deposition without parasitic deposition occurring.
- a first mixture of at least one carrier gas and at least one metal organic and a second mixture of at least one carrier gas and at least one Group V or Group VI compound are used in the process, the two mixtures separately in a system for separating the compound on the Substrate are introduced.
- the method is characterized in that the at least one metal organic between the substrate and the
- Group V or Group VI connection is initiated.
- the at least one organometallic is thus seen closer to the substrate than the group V or group VI compound.
- This advantageously has the effect that the thickness of parasitic deposition is considerably reduced, since the deposition is only carried out where it is desired, namely on the substrate.
- the deposition rate is increased regularly and the layers are highly pure in comparison to layers which have been deposited according to the prior art.
- a group II or a group III or a group IV compound or mixtures thereof can be selected as the metal organic.
- Barium-strontium compounds (group II) or trimethylgallium, trimethylaluminium and trimethylindium (group III) or titanium isopropoxide (group IV) may be mentioned as exemplary organometallics.
- NH 3 and / or AsH 3 and / or PH 3 can be selected as the group V compound and oxygen or diethytellur can be selected as the group VI compound.
- the method is not restricted to the choice of such connections. Rather, the method can basically be used to deposit compounds on a substrate by means of organometallic gas phase deposition.
- Suitable carrier gases for the compounds are hydrogen and / or nitrogen and / or argon.
- trimethyl gallium can be selected as the group III compound and NH 3 as the group V compound, each with hydrogen as the carrier gas.
- the metal organic / carrier gas mixture is introduced between the substrate and the NH 3 / carrier gas mixture.
- a MOCVD system has at least two gas inlets. A first for a first mixture and at least a second for a further mixture.
- the gases themselves are in storage containers.
- means, in particular at least two three-way valves, are arranged between the gas inlets of the system and the storage containers for the gases in so-called gas manifolds. Suitable quick-release couplings can also be arranged.
- the operator of such a system is able to conveniently and flexibly route gases to the parts of the system where they are are needed. This means that the gas inlets for the gas mixtures can be swapped quickly.
- Figure 1 shows schematically a MOCVD system according to the prior art with two gas inlets 4, 5 for an upper and a lower compartment.
- the precursors are guided separately from one another by a divider plate 1 to a substrate 2 to be coated.
- the MOCVD system is compartmentalized by the divider plate 1 into an upper and a lower space behind the gas inlets 4, 5.
- the substrate 2 can be, for example, a two
- the substrate 2 is introduced into a susceptor 6, which is designed here as a rotatable plate.
- the walls of the plant are only hinted at. This means that only one wall 3 was shown in the present case.
- the front wall and the ceiling, as seen in the viewing direction, are not shown in order to ensure an insight into the system.
- Fig. 2 is a cross section through the system along an imaginary line between the gas inlets and a cooling 7 in front of the susceptor (not shown).
- the cooling 7 is only hinted at in FIG. 2.
- the gas inlet 5 is cum / carrier gas mixture (TMG / H 2 ) and the gas inlet 4 occupied by the NH 3 / carrier gas mixture (NH 3 / H 2 ).
- TMG / H 2 cum / carrier gas mixture
- NH 3 / carrier gas mixture NH 3 / H 2
- the two gas streams initially remain separated from one another by the divider plate 1 until they are mixed behind the divider plate 1 and reach the substrate on the susceptor.
- the organometallic / carrier gas mixture is passed between the substrate and the NHs / carrier gas mixture.
- FIG. 3 shows the mixing of the reactants above the indicated cooling 7 shortly before the susceptor 6.
- the denser ammonia / carrier gas gas mixture diffuses in the direction of the substrate on the susceptor 6, where it mixes with the metal organic / carrier gas mixture.
- GaN is deposited on and in front of the substrate, which catalytically accelerates the decomposition of the precursors. The total gas mixture does not reach the ceiling of the plant, so that parasitic deposition on GaN is avoided there.
- the X-axis shows the local coordinates along a substrate or a wafer.
- the wafer is indicated by the black bar.
- the deposition rate after one hour is only about 1.3 microns GaN.
- the method according to the invention in which the TMG / H 2 mixture according to the invention is passed between the substrate and the NH 3 / carrier gas mixture, that is to say locally closer to the substrate, enables an on average much higher deposition rate of approximately 4 to 5 microns.
- rometer GaN Due to the rotatable susceptor 6, the deposition takes place uniformly on the wafer (FIG. 4b). The high deposition rates upstream of the wafer enable GaN to be deposited on this wafer with very high purity.
- the high deposition rate is due to the fact that the gas phase does not become impoverished due to parasitic deposition on the system walls.
- the gases are therefore available for deposition on the substrate.
- the deposition of GaN shown in FIGS. 2 to 4 is only an example.
- the metal organics include e.g. a mixture of barium and strontium diketonates and titanium alkoxides, e.g. Titanium isopropoxide.
- the mixture of metal organics is introduced into the system between the substrate and oxygen as a Group VI compound.
- FIG. 5 shows a switching device for the gas inlets of an MOCVD system.
- the manifold 52 is with a reservoir
- the manifold 51 is connected to a storage container for a carrier gas / group V or group VI gas mixture and is guided to the pneumatic 3/2-way valve VI.
- the valves VI and V2 are connected via the lines to the upper compartment and the lower compartment 5 of the gas inlets. In the unpressurized state is ⁇ V2 to the upper compartment 4 and opened to the lower compartment 5 towards VI (s. Fig. 5). The gases are fed into the system as in the prior art.
- Both valves VI and V2 are switched with only one N 2 pressure line 53 via a manually operated valve V3.
- the mixture of carrier gas (s) and at least one organometallic substance is then passed under pressure into compartment 5, that is to say between a substrate on a susceptor 6 and a mixture of carrier gas (s) and at least one group V or group VI compound.
- the latter gas mixture is then passed into compartment 4.
- the divider plate 1 is only indicated in FIG. 5 and, as shown in FIGS. 1 to 3, leads almost to the susceptor 6.
