Latest Patents

Mark A Alexander holds 1 patent for his invention titled "Electronically Actuated Valve." This invention relates to a method and apparatus for the rapid delivery of reactants to a substrate processing chamber. The electronically controlled valve assembly allows for the quick delivery of pulses of reactants, improving the overall processing efficiency. The valve assembly consists of a valve body with a valve seat, at least one gas inlet, and one gas outlet positioned below the seat. A piston within the valve body is selectively movable to open and close the valve. The actuation of the valve assembly is achieved by sending current to a solenoid coil, which generates a magnetic field that interacts with an adjacent magnetic member, facilitating the movement of the piston.
