  • Patent number: 6374859
    Abstract: A manifold system for incorporation in a gas panel distribution system for semi-conductor manufacturing includes a plurality of individual manifold blocks with each manifold block having a fluid passageway with an entrance and exit port accessing a common surface. Adjacent manifold blocks are removably interconnected to permit the respective fluid passageways to be in position for interconnection. A plurality of active components can be sealingly fastened to the individual manifold blocks to complete the interconnection of the respective fluid passageways. Each active component can bridge over a pair of adjacent individual manifold blocks and form with the individual manifold blocks an operative gas stick for delivering gas to a semiconductor tool. The individual manifold blocks can be identical in configuration and can include a first upper flange on one side and a second lower flange on an opposite side to enable an interlocking of adjacent manifold blocks.

  • Patent number: 6044701
    Abstract: A thermal mass flow controller having a thermal mass flow meter with an orthogonal thermal mass flow sensor includes a base defining a primary fluid flow path therein for carrying a flow of fluid to be metered. A pressure dropping bypass is positioned in the primary fluid flow path. A flow measuring portion of a thermal mass flow sensor is oriented substantially transversely or orthogonally with respect to and is in communication with the primary fluid flow path. The flow measuring portion includes a portion of an electrical bridge for determining a temperature of the sensor and produces a mass flow rate signal in response thereto. A valve is connected to an outlet of the primary flow path to control the flow of fluid in response to the mass flow rate signal.

  • Patent number: 5730181
    Abstract: A mass flow controller and purifier has a canister arranged at right angles to a flow path through the mass flow controller. The canister holds a contaminant scavenging material which a gas stream contacts as it flows to remove a contaminant such as water. A purified process gas stream is fed through a bypass of a mass flow meter. A portion of the gas is supplied to a mass flow sensor which generates a signal indicative of a rate of mass flow. The mass flow signal is amplified and the amplified mass flow signal is linearized in a linearizer. The linearized mass flow signal is fed to a comparator which compares the linearized mass flow signal with an error signal and provides an output signal indicative of a mass rate of flow through the mass flow meter. A valve is connected to the mass flow meter and is controlled by the mass flow meter signal to meter the gas.

  • Patent number: 5303731
    Abstract: A liquid flow controller for metering a flow of liquid has an inlet to receive the liquid. The inlet feeds the liquid to a high resistance liquid flow path across which a pressure drop arises. A pressure sensor measures the liquid flow induced pressure drop and generates pressure drop signal which is fed to an electronic circuit. A temperature sensor is connected to the high resistance liquid flow path and generates a temperature signal which is also fed to the electronic circuit. The circuit energizes a viscosity-normalized liquid flow signal, which is compared to a set point signal to generate an error signal. A valve connected downstream of the high resistance liquid flow path to control the flow of liquid is driven by the error signal and thereby controls the flow of liquid.
