Definitions
- the invention relates to a method for producing group III-N, group III-V-N and metal-nitrogen component structures on Si substrates and to a corresponding device.
- a high level of homogeneity of the layers is also necessary.
- a layer thickness variation in the monolayer range with an active In x Ga N_ x N quantum well layer, such as is used in LEDs can lead to a shift of the maximum emission wavelength by several nanometers. With lasers, such a variation in wavelength is completely unacceptable.
- the indium concentration which is strongly dependent on the deposition temperature and the temperature of the surrounding walls.
- the low-temperature seed or buffer layers on the Si substrate must also have the best possible homogeneity so that the layer above has a constant quality over the wafer.
- the invention is based on the object of specifying a method and a device for the cost-effective production of group III-N or group III-VN component structures on Si substrates.
- a solution to this problem according to the invention is specified in the independent claims directed to a method or a device.
- a horizontal MOCVD reactor is used in a manner known per se which, owing to the structure of the growth chamber and the rotating susceptors, ensures great homogeneity and reproducibility of the deposited layers. Possible embodiments of such MOCVD reactors are described below.
- the advantage of the susceptors rotating on a gas cushion is the improved homogeneity of the layers with virtually no abrasion. In other, mechanically driven systems, particles are created by the abrasion
- Layer growth or the purity of the layers can negatively affect.
- MOCVD systems used according to the invention and Si substrates inexpensive production of Group III-N components is possible with a high component yield and low use of source materials.
- the efficiency of Group III elements e.g. B. Ga is over 10% in a multi-disk reactor.
- the precise control of the substrate temperature as well as the temperature of the surrounding walls or the ceiling of the growth chamber is very important for high reproducibility and homogeneity, since the installation depends very sensitively on these parameters.
- a special gas inlet geometry is used, which is distinguished by the fact that undesired cross-reactions between the gases do not take place.
- the special temperature profile in the The reactor and the temperature management and control system are designed in such a way that any interactions of the gases are suppressed, so that reproducibility is guaranteed and the efficiency of the raw materials is increased.
- the use of a low-temperature seed and / or a buffer layer enables the substrate in the MOCVD system described to be uniformly grown or grown over.
- the device is therefore designed in such a way that precise control of the static and dynamic temperature distribution on the Si substrates is possible.
- the temperature interval is 300-1600 ° C. This system is necessary for both the seed and active layers.
- the germ layer is understood to mean a three-dimensional layer or three-dimensional islands which are not necessarily closed and which are a few nanometers thick and which, in spite of possibly poor crystalline and / or stoichiometric properties, form the basis for the subsequent one
- Layer growth serves or from which the further layer growth starts.
- epitaxy on Si it is often necessary so that a preferred orientation from non-polar Si to, for example, polar GaN is given and the buffer or component layer can be deposited on it in the first place.
- growth on Si is also possible, for example directly with a low-temperature buffer layer as the first layer.
- Such seed and / or buffer layers on Si are - according to the invention of great importance - for the successful growth of Group III-N and Group III-VN layers on Si. Because only a closed germ and / or buffer layer, for example made of a Group III-V material such as z. B.
- the method according to the invention is made possible on large-area substrates or m multi-wafer systems by the homogeneity of the layers deposited in these systems, because a uniformly thick seed and / or buffer layer is e.g. necessary to avoid silicon nitriding in partial areas of the substrate due to a locally too thin seed and / or buffer layer. Furthermore, the homogeneity of the inferior germ and / or buffer layer from the crystalline point of view is important in order to ensure a uniform quality of the applied layers over a large area. If the thickness is inhomogeneous, the seed and / or buffer layer does not crystallize uniformly at higher temperatures and then leads to fluctuations in the crystalline quality and thus e.g. in the case of LED structures, fluctuations in the light output over large areas of the wafer.
- the m-situ measurement of the reflectivity which is advantageously used serves to monitor the layer growth. Examples of such m-situ reflective Activity measurements are described in connection with the drawings. This allows the thickness and composition of the layer to be monitored during growth and, for example, to adjust the parameters in the event of a slight drift, so that the layers produced can be used or, for example, a decision can be made before the end of growth whether the layers continue to grow or later should be processed further.
- the reflectivity measurement is very helpful in the growth of the low-temperature seed layer and / or the low-temperature buffer and the Group III-N layer deposited on the seed or buffer layer at higher temperatures.
- the layer thickness and the smoothness or closeness of the deposited layers can be assessed very well.
- Si tends to nitridate under NH 3 or other nitrogen starting materials which are used, for example, in group III-N layer growth for the nitrogen component at higher temperatures.
- group III-N layer growth for the nitrogen component at higher temperatures.
- growth of, for example, crystalline Group III-N layers is not possible on such nitrided Si. In most cases there is then no growth or of polycrystalline material which has a modified or low reflectivity, which can be observed in the measurement. If, for example, due to poor pretreatment of the substrate or poor substrate quality, the Group III-N layer deposited thereon is not completely closed, the underlying Si partially extends below the already deposited layer and thus leads to a unusable
- Possibilities are specified in the subclaims as to how the variation in the layer and growth parameters can reduce the dislocation density and the formation of cracks in the applied component layer. These options can be used individually, or in combination, but also multiple and multiple combined. Since Si and, for example, GaN have different lattice constants and crystal lattices, dislocations are formed at the interface, among other things. The thermal lattice mismatch of these materials also leads to the formation of cracks from a layer thickness of approx. 1 ⁇ m, for example when cooling the layer [Monemar] or during growth when setting different temperatures for e.g. B. InGaN growth and AlGaN or GaN.
- the temperature in MOCVD growth is often varied by several hundred degrees Celsius.
- Nikishin et al. have shown that growth in the MBE can avoid the formation of cracks by growing a germ or buffer layer of, for example, A1N made alternately from metal and then nitriding [Nikishin].
- This layer does not necessarily have to have a stoichiometric ratio of Group III to Group V components.
- the materials mentioned in a subclaim also include so-called layer grids such as WSe 2 , which are soft in one direction, ie have sliding planes. This makes it possible to deposit layers with little dislocation and cracks.
- Li et al. showed that by partially masking a group III nitride layer using methods such as ELO, ELOG or LEO, the layer deposited on it is at least less dislocated above the masked areas [Li]. Multiple combinations of this process can lead to layers with little dislocation. Furthermore, by applying such masks with a suitable expansion coefficient, the formation of cracks in the deposited Group III nitride layer can be reduced. The reduction m of the dislocation density can also be achieved with the method described by Iwaya et al. described growth of low-temperature intermediate layers take place [Iwaya]. The author describes how the dislocation density can be greatly reduced by layers that do not require any further processing, i.e.
- the thermally induced stress and thus the cracking can be reduced or reduced.
- the Si band gap is only about 1.1 eV
- the photon energies generated with, for example, GaN-based components are usually significantly higher, in contrast to the use of sapphire substrates, a considerable part of the emitted photons is absorbed in Si.
- the methods described in further subclaims can be used.
- a metal of sufficient thickness is deposited on the substrate by means of evaporation, sputtering or
- a partial high-quality overgrowth such as, for example, is preferably achieved by applying a partial masking, for example of SiO 2 and / or SiN x or metal strips from, for example, W on an AlN or GaN seed or buffer layer and the subsequent overgrowth in Kawaguchi et al. described enables [Kawaguchi].
- the method according to the invention advantageously serves to reduce dislocations. This masking can also be carried out several times and also in a staggered arrangement, so that the efficiency of this layer as a reflector but also as a material-improving method is increased.
- Light wavelength by applying one or more layers with different refractive indices to each other and / or to the epitaxial layer and / or the surrounding medium, which is usually air or at a LED is often a plastic.
- the combination of two Bragg mirrors to create a vertical light beam is also very suitable for the lower mirror.
- intermediate layers can be provided between the silicon substrate and active components for optimal adaptation to the respective task or use of the component structure to be produced.
