  • Patent number: 8906446
    Abstract: An apparatus is provided having a closable chamber that can be sealed and is capable of withstanding an increased pressure and high temperature. The chamber has several inlet ports for the supply of various process liquids, such as deposition solutions, DI water for rinsing, etc., and a port for the supply of a gas under pressure. The apparatus also includes a solution heater and a control system for controlling temperature and pressure in the chamber. Uniform deposition is achieved by carrying out the deposition process under pressure and under temperature slightly below the boiling point of the solution. The solution can be supplied from above via a shower head formed in the cover, or through the bottom of the chamber. Rinsing or other auxiliary solutions are supplied via a radially moveable chemical dispensing arm that can be arranged above the substrate parallel thereto.
