Abstract:
In one or more embodiments, a method for depositing a carbon hard-mask material by plasma-enhanced chemical vapor deposition (PECVD) includes heating a substrate contained within a process chamber to a temperature in a range from about 100 C to about 700 C and producing a plasma with a power generator emitting an RF power of greater than 3 kW. In some examples, the temperature is in a range from about 300 C to about 700 C and the RF power is greater than 3 kW to about 7 kW. The method also includes flowing a hydrocarbon precursor into the plasma within the process chamber and forming a carbon hard-mask layer on the substrate at a rate of greater than 5,000/min, such as up to about 10,000/min or faster.
