    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: Transistors fabricated on SSOI (Strained Silicon On Insulator) substrate, which comprises a strained silicon layer disposed directly on an insulator layer, have enhanced device performance due to the strain-induced band modification of the strained silicon device channel and the limited silicon volume because of the insulator layer. The present invention discloses a SSOI substrate fabrication process comprising various novel approaches. One is the use of a thin relaxed SiGe layer as the strain-induced seed layer to facilitate integration and reduce processing cost. Another is the formation of split implant microcracks deep in the silicon substrate to reduce the number of threading dislocations reaching the strained silicon layer. And lastly is the two step annealing/thinning process for the strained silicon/SiGe multilayer film transfer without blister or flaking formation.
