  • Patent number: 9314854
    Abstract: A method of drilling holes comprises ductile mode drilling the holes in a component of a plasma processing apparatus with a cutting tool wherein the component is made of a nonmetallic hard and brittle material. The method comprises drilling each hole in the component by controlling a depth of cut while drilling such that a portion of the brittle material undergoes high pressure phase transformation and forms amorphous portions of the brittle material during chip formation. The amorphous portions of the brittle material are removed from each hole such that a wall of each hole formed in the component has an as drilled surface roughness (Ra) of about 0.2 to 0.8 ?m.

  • Publication number: 20150276533
    Abstract: A device/method for sensing a physical parameter, including a sensor die and a stress-sensitive circuit. The sensor die includes a semiconductor substrate and a cavity that creates an elastic element that bends in response to the physical parameter exerted on the sensor die. The elastic element includes at least at least one rigid island formed within the cavity, a thin area surrounding the at least one rigid island and having smaller thickness than the rigid island, and at least one stress concentrator at least partially formed in the thin area of the elastic element on the side of the substrate opposite the cavity. The stress-sensitive circuit includes at least one stress-sensitive component formed in the thin area of the elastic element. The at least one stress concentrator increases stress in the locations of the at least one stress-sensitive component resulting in an increase of the device sensitivity to the physical parameter.
