  • Publication number: 20190326416
    Abstract: Structures for a field-effect transistor and methods of forming a structure for field-effect transistor. A gate electrode is arranged in a lower portion of a trench in an interlayer dielectric layer, and a liner is formed inside an upper portion of the trench and over a top surface of the interlayer dielectric layer. A dielectric material is deposited in in the upper portion of the trench and over the liner on the top surface of the interlayer dielectric layer. The dielectric material is polished with a polishing process to remove the dielectric material from the liner on the top surface of the interlayer dielectric layer and to form a cap comprised of the dielectric material in the upper portion of the trench. The liner on the interlayer dielectric layer operates as a polish stop during the polishing process.

  • Publication number: 20180366373
    Abstract: The present disclosure describes a method to form silicon germanium (SiGe) source/drain regions with the incorporation of a lateral etch in the epitaxial source/drain growth process. For example, the method can include forming a plurality of fins on a substrate, where each of the plurality of fins has a first width. The SiGe source/drain regions can be formed on the plurality of fins, where each SiGe source/drain region has a second width in a common direction with the first width and a height. The method can also include selectively etching—e.g., via a lateral etch—the SiGe source/drain regions to decrease the second width of the SiGe source/drain regions. By decreasing the width of the SiGe source/drain regions, electrical shorts between neighboring fins can be prevented or minimized. Further, the method can include growing an epitaxial capping layer over the Si/Ge source/drain regions.

  • Patent number: 10147174
    Abstract: A substrate inspection device is provided, which includes a main body, a bearing module, an illuminating and camera module and a control module. A mask is held by the bearing module, which has an opening. The illuminating and image capturing module is disposed on the lifting unit. After receiving the first detecting signal, the control module accordingly drives the lifting unit to shift towards the first direction, such that the illuminating and image capturing module moves closer to the substrate. The control module then controls the shifting unit to drive the light-emitting component to project a first spot-light on the substrate through the opening, and controls the shifting unit to move by a step manner so as to carry the bearing module. The control module also controls the illuminating and image capturing module to capture images the first regions of the substrate and to generate the first images.
