  • Publication number: 20190318193
    Abstract: A method for crystal analysis includes identifying a crystalline region on a device where an electronic channeling pattern is needed to be determined, acquiring a whole image for each of a plurality of different positions for the crystalline region using a scanning electron microscope (SEM) as the crystalline region is moved to different positions. Relevant regions are extracted from the whole images. The images of the relevant regions are stitched together to form a composite map of a full electron channeling pattern representative of the crystalline region wherein the electronic channeling pattern is provided due to an increase in effective angular range between a SEM beam and a surface of the crystal region.

  • Patent number: 10109737
    Abstract: A method of forming high germanium content silicon germanium alloy fins with controlled insulator layer recessing is provided. A silicon germanium alloy (SiGe) layer having a first germanium content is provided on a surface of an insulator layer using a first condensation process. Following the formation of a hard mask layer portion on the SiGe layer, a second condensation process is performed to convert a portion of the SiGe layer into a SiGe fin of a second germanium content that is greater than the first germanium content and other portions of the SiGe layer into a shell oxide structure located on sidewalls of the SiGe fin. After forming a fin placeholder material, a portion of each shell oxide structure is removed, while maintaining a lower portion of each shell oxide structure at the footprint of the SiGe fin.

  • Publication number: 20180277367
    Abstract: A method for reducing crystalline defects in a semiconductor structure is presented. The method includes epitaxially growing a first crystalline material over a crystalline substrate, epitaxially growing a second crystalline material over the first crystalline material, and patterning and removing portions of the second crystalline material to form openings. The method further includes converting the first crystalline material into a non-crystalline material, depositing a thermally stable material in the openings, depositing a capping layer over the second crystalline material and the thermally stable material to form a substantially enclosed semiconductor structure, and annealing the substantially enclosed semiconductor structure.

  • Patent number: 9984941
    Abstract: A semiconductor material stack of, from bottom to top, a first semiconductor material having a first lattice constant and a second semiconductor material having a second lattice constant that may or may not differ from the first lattice constant and is selected from an III-V compound semiconductor and germanium is provided. The second semiconductor material of the semiconductor material stack is then scanned using an atomic force microscope (AFM) operating in a tapping mode to provide an AFM image of the second semiconductor material of the semiconductor material stack. The resultant AFM image is then analyzed and crystal defects at a topmost surface of the second semiconductor material of the semiconductor material stack can be measured.

  • Publication number: 20180143634
    Abstract: An autonomous path treatment system and associated path treatment method uses a mobile path recording device having a locator, a processor and firmware to capture a sequence of coordinates and directions of travel of a path as the mobile device is moved along the path and generate a path program file. The system also has an autonomous path treatment robot having: a treatment mechanism for treating the path; a controller having a processor and memory storing firmware that when executed obeys steps of the path program file to control the motor and the treatment mechanism to treat the path; and a server configured to execute a path program to process the captured sequence of coordinates and directions into the path program file containing instructions for controlling the autonomous path treatment robot to treat the path based upon the coordinates.
