  • Patent number: 9234281
    Abstract: The invention relates to a liquid-phase method for the thermal production of silicon layers on a substrate, wherein at least one higher silicon that can be produced from at least one hydridosilane of the generic formula SiaH2a+2 (with a=3-10) being applied to a substrate and then being thermally converted to a layer that substantially consists of silicon, the thermal conversion of the higher silane proceeding at a temperature of 500-900° C. and a conversion time of ?5 minutes. The invention also relates to silicon layers producible according to said method and to their use.

  • Publication number: 20130240892
    Abstract: The present invention relates to a process for conversion of semiconductor layers, especially for conversion of amorphous to crystalline silicon layers, in which the conversion is effected by treating the semiconductor layer with a plasma which is generated by a plasma source equipped with a plasma nozzle (1). The present invention further relates to semiconductor layers produced by the process, to electronic and optoelectronic products comprising such semiconductor layers, and to a plasma source for performance of the process according to the invention.
