  • Dissolved Ammonia Delivery System

    DI-NH3 - MKS Instruments

    MKS' DI-NH3 is a compact, stand-alone system providing dissolved ammonia water. With Semiconductor 3D IC architectures using new materials like Cu-Co and Si-SiGe, the ability to wet clean with precise alkaline chemistries is growing in frequency and importance. The DI-NH3 delivers dissolved ammonia, providing optimal cleaning capability in an alkaline chemistry, minimizing material loss and contamination and inhibiting Electrostatic Discharge (ESD). Using closed-loop control, conductivity and pressure are kept stable under changing flow conditions. The dissolved ammonia concentration is monitored and adjusted, delivering the specific NH4OH concentration needed. Dissolved ammonia’s alkaline chemistry provides ESD protection during rinsing, particle lift-off, and residual photoresist removal in middle-of-line (MOL) and prevents corrosion of cobalt/copper interfaces.

  • High Voltage Grounding Relays

    B-1007 - ROSS ENGINEERING CORPORATION

    Extra high voltage, low corona, grounding relays of the air insulated type.  Peak test ratings up to 300kV and 100 amps continuous.  Units can be operated either by solenoid, motor, or air cylinder, with spring or gravity return.  All models have spherical contacts.  When voltage transient limiting is required, some models have an adjustable sphere gap.  Also available are units with built-in high voltage discharge resistors with energy dissipation capabilities from 50 to 10,000 ohms.  Some units can be reduced in height if full line to ground voltage is connected to the top high voltage contact only and the other high voltage terminal is operating at, or near, ground potential.  Line to ground voltage can also be increased by adding insulation between lower high voltage contact and ground.  Normally mounted base down.  Base up mounting if specified.

  • Earth Tester

    TAURUS PRECIOHM ET - Taurus Powertronics Systems

    The TAURUS PRECIOHM ET is one of the specially designed products by TAURUS to measure earth resistivity and earth resistance in a power station. These tests are performed based on 4 point (Wenner) and 3 point (fall of potential) methods respectively. All electrical equipment in the substation and power stations are electrically connected to station earth mat with earth electrodes. The earth electrode ensures that in the event over voltage on the system due to system fault or lighting discharges etc., the parts of the equipment which are normally ”dead” as far as voltages are concerned; do not attain dangerously high potentials. An earth electrode will only be effective so long it has a low resistance to the earth and can carry large currents without deteriorating. Thus the resistance of earth electrode should be low to give good protection and it must be continuously measured and monitored in all the substations and power stations.

    Neutronics Manufacturing Co.

    Measure DC resistance of transformers windings etc. Introduction: The NMC ''TDR'' is a high precision, new generation, light weight large output current and micro-processor controlled tester. This replaces old DC wheat stone bridge and double arm bridge for measurement of DC resistance. ''TDR'' adopts new advanced test current power supply technology, four terminal measurement, digital display of resistance value and test current. ''TDR'' is powered by 220V AC mains single phase supply. The measurements are accurate as the test current is highly stable. High automation is achieved with automatic discharge warning.Principle: The constant current generated is fed to the resistance under test through the current terminals and the voltage drop across the resistance under test is measured and displayed in ohms. A true four terminal measurement is used to eliminate the need for lead resistance compensation.
