Abstract: A method of forming a contact in a semiconductor device deposits a refractory metal contact layer in a contact hole on a conductive region portion in a silicon substrate. The refractory metal contact layer is reacted with the silicide region prior to a plasma treatment of a contact barrier metal layer formed within the contact hole. This prevents portions of the refractory metal contact layer from being nitridated prior to conversion to silicide.

Abstract: The present invention relates to a device for protecting high frequency RF integrated circuits from ESD damage. The device comprises at least one varactor-LC circuit tank stacked to avoid the power gain loss by the parasitic capacitance of ESD circuit. The varactor-LC tank could be designed to resonate at the RF operating frequency to avoid the power gain loss from the parasitic capacitance of ESD circuit. Multiple LC-tanks could be stacked for further reduction in the power gain loss. A reverse-biased diode is used as the varactor for both purposes of impedance matching and effective ESD current discharging. Because the inductor is made of metal, both the inductor and the varactor can discharge ESD current when ESD condition happens. It has a high enough ESD level to prevent ESD discharge.
