PROCESS FOR PREPARING HIGHER HALOSILANES AND HYDRIDOSILANES

摘要

The invention relates to a process for preparing higher halosilanes by disproportionation of lower halosilanes. The invention further relates to a process for preparing higher hydridosilanes from the higher halosilanes prepared by disproportionation. The invention further relates to mixtures containing at least one higher halosilane or at least one higher hydridosilane prepared by the process described. Finally, the invention relates to the use of such a mixture containing at least one higher hydridosilane for producing electronic or optoelectronic component layers or for producing silicon-containing layers.
