Definitions
- the invention relates to a method for producing a semiconductor structure, in particular a semiconductor structure for optoelectronics.
- SiC silicon carbide
- a 3C-SiC layer is formed by carbonizing the surface of a silicon wafer serving as a donor disk, then bonding the SiC layer of the silicon donor disk to a polycrystalline SiC support disk, and subsequently the rest of the silicon wafer. Donor disk is removed to expose the SiC layer.
- polycrystalline SiC as the substrate has the advantage that the thermal expansion coefficients of GaN and SiC are relatively close to each other, in contrast to silicon. This can be advantageous for further thermal treatment steps.
- WO03 / 034484 discloses another process by means of which ion crystalline synthesis ("ion beam synthesis", IBS) can be used to produce thin, monocrystalline silicon carbide layers of the polytype 3C on silicon substrates (IBS 3C-SiC on silicon) in this process by implanting carbon ions into a silicon substrate, thermally treating and ablating the parts of the silicon substrate damaged by the ion implantation.
- IBS ion crystalline synthesis
- WO98 / 14986 discloses a method with which two material layers can be separated by irradiation of the interface of these material layers with electromagnetic radiation. The separation is based on the thermal decomposition of one of the two material layers near the interface.
- this method can be used to produce optoelectronic devices made of GaN or InGaN on sapphire, and subsequently the Sapphirsubstrat by Separate thermal decomposition of GaN or InGaNs near the interface between sapphire and GaN or InGaN.
- a disadvantage of this laser lift-off method is the restriction to material systems which decompose under the influence of electromagnetic radiation or by thermal action. Furthermore, this technologically complex process requires the use of intensive lasers with wavelengths that are above the energy band gap of the wide band gap semiconductors used.
- Object of the present invention which is to provide high-quality epitaxial layers for optoelectronics, which avoid the disadvantages of the known in the prior art method.
- the object of the invention is achieved by a method for producing a semiconductor structure, comprising providing an SC-SiC semiconductor layer structure comprising a monocrystalline 3C-SiC layer produced by implantation of carbon in silicon on a first substrate made of silicon, applying one for the production of Optoelectronic devices suitable epitaxial layer of a nitride compound semiconductor on the 3C-SiC

- IBS 3C-SiC also has the advantage over 3C-SiC structures produced by other methods, as well as compared to SiC of other polytypes such as 4H and 6H, that it sufficiently smoothes out solely by means of a CMP polishing and thus can be prepared for a subsequent epitaxy step.
- the 3C-SiC substrate is preferably formed by implanting carbon ions into a silicon substrate, thermally treating the silicon substrate, thereby forming a buried monocrystalline layer of 3C-SiC at a certain depth of the silicon substrate, subsequently ablating the upper layers of the silicon substrate until the monocrystalline 3C-SiC layer is exposed and then a surface of the exposed 3C-SiC layer is chemo-mechanically polished.
- silicon wafer is intended to include all silicon
- silicon wafers having a crystal orientation (100), (110) or (111) and produced from either FZ (floatzone) or CZ (Czochralski) -grown crystals are suitable for this purpose.

- the implantation of carbon ions is preferably carried out at a shallow angle in order to suppress a lattice-guiding effect (the so-called channeling). Therefore, it is particularly preferable to implant the carbon ions at an angle of 1-10 ° to a surface normal of the silicon wafer.
- the upper silicon layer and the non-random transition region lying above the buried monocrystalline 3C-SiC layer are then removed, preferably by means of a suitable chemical etching step, by gas phase etching or reactive ion etching, by thermal oxidation and subsequent etching or by mechanical or chemical-mechanical removal processes such as Sanding, lapping or polishing.
- the 3C-SiC layer is then chemo-mechanically polished, preferably with a slurry containing colloidal silicate (silica). Pretreatments of the exposed 3C-SiC layer prior to CMP polishing are not provided. In particular, mechanical pre-polishing and thermal oxidation in combination with the CMP polishing are not provided and also not preferred.
- the polishing time is preferably less than 30 minutes.
- Particularly preferred is a polishing time of less than 15 min.
- Very particularly preferred is a polishing time of less than 5 min.
