  • Method for forming ultra-high strength elastic diamond like carbon structure
    Publication number: 20050066882
    Abstract: A technique of forming an elastic DLC structure having ultra high strength by controlling an amount of focused ion beam current from 0.1 to 10 pA, and a growth rate in the range from 0.6 to 5 ?m/min. and by using hydrocarbon gas such as phenanthrene (C14H10) and pyrene (C16H10), as source gas, in an apparatus having a gas nozzle for locally maintaining a higher partial gas pressure near the substrate and a structure for confining the gas on the substrate. In this manner, the elastic DLC having the ultra high strength can be obtained of which a hardness can be controlled in a relatively broader range.
