  • Patent number: 9793116
    Abstract: The invention provides a reactor for the manufacture of silicon by chemical vapor deposition (CVD), the reactor comprises a reactor body that can rotate around an axis with the help of a rotation device operatively arranged to the reactor, at least one sidewall that surrounds the reactor body, at least one inlet for reaction gas, at least one outlet for residual gas and at least one heat appliance operatively arranged to the reactor. The reactor is characterized in that during operation for the manufacture of silicon by CVD, the reactor comprises a layer of particles on the inside of at least, one sidewall.
    Type: Grant
