Patents

Patent #7,618,027

This patent is for a vaporizing device for control, delivery, and purification of water vapor in conjunction with a carrier gas. The patent is used in RainMaker humidification systems (RHS) to control the transfer and purification of water vapor directly into a carrier gas stream including inert, corrosive, and flammable gases, such as hydrogen, at a wide range of flow rates for use in solar, microelectronics, and other critical process applications.

Patent #7,625,015B2

This patent is for a novel adhesive and weld-free assembly technique for working with membranes and ultrapure materials. The patented process allows for the simultaneous sealing of multiple tubes within a single outer shell when an external radial compressive force is applied and is used in the RainMaker Humidification System (RHS).

Patent #8,282,708

This patent is for a novel method of producing ultrapure steam. The method is based on the ability to generate a high rate of diffusion of water vapor through a non-porous membrane. The patent is used in RASIRC products for a variety of applications including wet thermal oxidation and wafer cleaning for MEMS and semiconductor devices, backside passivation for solar cells, and steam annealing for amorphous metal oxide thin film transistors (TFTs).
