摘要： A thermally stable nickel germanosilicide on SiGe integrated circuit device, and a method of making the same, is disclosed. During fabrication of the device iridium or cobalt is added at the Ni/SiGe interface to decrease the sheet resistance of the device. The device comprising nickel silicide with iridium on SiGe shows thermal stability at temperatures up to 800° C. The device comprising nickel silicide with cobalt on SiGe shows a decrease in the sheet resistance with temperature, i.e., the resistance remains low when annealing temperatures extend up to and beyond 800° C.

摘要： An integrated circuit device, and a method of manufacturing the same, comprises an epitaxial nickel silicide on (100) Si, or a stable nickel silicide on amorphous Si, fabricated with a cobalt interlayer. In one embodiment the method comprises depositing a cobalt (Co) interface layer between the Ni and Si layers prior to the silicidation reaction. The cobalt interlayer regulates the flux of the Ni atoms through the cobalt/nickel/silicon alloy layer formed from the reaction of the cobalt interlayer with the nickel and the silicon so that the Ni atoms reach the Si interface at a similar rate, i.e., without any orientation preference, so as to form a uniform layer of nickel silicide. The nickel silicide may be annealed to form a uniform crystalline nickel disilicide. Accordingly, a single crystal nickel silicide on (100) Si or on amorphous Si is achieved wherein the nickel silicide has improved stability and may be utilized in ultra-shallow junction devices.

摘要： An Ir combination film has been provided that is useful in forming an electrode of a ferroelectric capacitor. The combination film includes tantalum and oxygen, as well as iridium. The Ir combination film effectively prevents oxygen diffusion, and is resistant to high temperature annealing in oxygen environments. When used with an underlying Ta or TaN layer, the resulting conductive barrier also suppresses to diffusion of Ir into any underlying Si substrates. As a result, Ir silicide products are not formed, which degrade the electrode interface characteristics. That is, the Ir combination film remains conductive, not peeling or forming hillocks, during high temperature annealing processes, even in oxygen. A method for forming an Ir composite film barrier layer and Ir composite film ferroelectric electrode are also provided.
