  • Patent number: 9630218
    Abstract: An air-flushing device cleans a cleaning object by air-blowing to the object from a nozzle. The air-flushing device outputs a pressure value changing according to electromagnetic valve's opening/closing, and controls the valve's opening/closing based on two reference values of an upper-limit setting value and a lower-limit setting value lower than that. The air-flushing device closes the valve if the pressure value changes from lower than the upper-limit setting value to that or higher, and opens the valve if the pressure value changes from higher than the lower-limit setting value to that or lower.

  • Patent number: 9624577
    Abstract: Embodiments of the present disclosure relate to a metal-doped amorphous carbon hardmask for etching the underlying layer, layer stack, or structure. In one embodiment, a method of processing a substrate in a processing chamber includes exposing a substrate to a gas mixture comprising a carbon-containing precursor and a metal-containing precursor, reacting the carbon-containing precursor and the metal-containing precursor in the processing chamber to form a metal-doped carbon layer over a surface of the substrate, forming in the metal-doped carbon layer a defined pattern of through openings, and transferring the defined pattern to an underlying layer beneath the metal-doped carbon layer using the metal-doped carbon layer as a mask. An etch hardmask using the inventive metal-doped amorphous carbon film provides reduced compressive stress, high hardness, and therefore higher etch selectivity.
