  • Publication number: 20190326097
    Abstract: A microwave plasma chemical vapor deposition device for diamond synthesis. A microwave source generates a microwave signal, and a resonant cavity receives a plurality of process gases. The microwave signal is spread in a first mode at a first waveguide. A mode conversion antenna converts the first mode of the microwave signal into a second mode that is spread at a second waveguide. A coupling conversion cavity receives and transmits the microwave signal in the second mode to the mode conversion antenna thereby converting the second mode of the microwave signal into a third mode. A medium viewport receives the microwave signal in the third mode and transmits to the resonant cavity which enables the microwave signal to excite and discharge the process gases to form spherical plasma, carbon containing groups and atomic hydrogen thereby depositing a diamond film on a seed.

  • Patent number: 9150415
    Abstract: A topographic profile of a structure is generated using atomic force microscopy. The structure is scanned such that an area of interest of the structure is scanned at a higher resolution than portions of the structure outside of the area of interest. An profile of the structure is then generated based on the scan. To correct skew and tilt of the profile, a first feature of the profile is aligned with a first axis of a coordinate system. The profile is then manipulated to align a second feature of the profile with a second axis of the coordinate system.
