  • Patent number: 11003942
    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: 10840433
    Abstract: An ultra-small diameter and a tall bottom electrode for use in magnetic random access memory (MRAM) devices containing a multilayered MTJ pillar is provided. The bottom electrode is formed by depositing a thick bottom electrode layer on a surface of a metallic etch stop layer. The bottom electrode layer is then patterned by lithography and etching to provide a bottom electrode structure. An angled ion beam etch is thereafter used to trim the bottom electrode structure into a bottom electrode having a high aspect ratio (on the order of 10:1 or greater).

  • Patent number: 10755925
    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: 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.
