Patent ID: 8252375

Claim:
A process for coating of substrates comprising: inserting a substrate into a process chamber; plasma cleaning said substrate in the process chamber; pre-heating a vaporization chamber to a first temperature with a vaporization chamber heater; pre-determining a first specific volume of liquid silane to be used for the process; pre-determining a first amount of time to be used for the process; withdrawing said first specific volume of liquid silane from a first chemical reservoir; supplying the first specific volume of liquid silane to the heated vaporization chamber, wherein said heated vaporization chamber is fluidically coupled to said process chamber by a passage open continuously while said first specific volume of liquid silane is supplied to said heated vaporization chamber; and vaporizing said first specific volume of said liquid silane, wherein most of the vapor of said first specific volume of said liquid silane enters said process chamber through the open passageway, whereby some of the vapor of said first specific volume of said liquid silane reacts with the substrate to create a layer; allowing the vapor of said first specific volume of said liquid silane to remain in the process chamber for a first pre-determined amount of time, wherein said heated vaporization chamber is fluidically coupled to said process chamber by a passage open continuously during said first pre-determined amount of time, and wherein said process chamber is not evacuated during said first pre-determined amount of time.
