摘要： A method of depositing layers on a plurality of semiconductor substrates simultaneously, comprising the steps: cleaning of at least one respective surface of the substrates in a first reactor at a first substrate temperature Tred, transport of the substrates from the first reactor into a second reactor, and subsequent deposition of at least one respective layer on the semiconductor substrates in the second reactor at a second substrate temperature Tdep, wherein the semiconductor substrates are moved or stored during the cleaning step and during transport from the first reactor into the second reactor in an interruption-free manner in a reducing gas atmosphere as long as the substrate temperature is above a critical temperature Tc which is dependent on the substrate material and the material of the at least one layer to be deposited.

摘要： System for producing diffusion-inhibiting epitaxial semiconductor layers, by means of which thin diffusion-inhibiting, epitaxial semiconductor layers can be produced on large semiconductor substrates at a high throughput.The surfaces of the semiconductor substrates to be coated are first cleaned, and the substrates are then heated in a low pressure batch reactor to a first temperature (prebake temperature). The surfaces to be coated are next subjected to a hydrogen prebake operation at a first reactor pressure. In the next step the semiconductor substrates are heated in a low pressure hot or warm wall batch reactor to a second temperature (deposition temperature) lower than the first temperature, and after a condition of thermodynamic equilibrium is reached the diffusion-inhibiting semiconductor layers are deposited on the surfaces to be coated in a chemical gaseous deposition process (CVD) at a second reactor pressure higher than, equal to or lower than the first reactor pressure.
