  • Publication number: 20250089346
    Abstract: Embodiments of the present disclosure provide methods for forming merged source/drain features from two or more fin structures. The merged source/drain features according to the present disclosure have a merged portion with an increased height percentage over the overall height of the source/drain feature. The increase height percentage provides an increased landing range for source/drain contact features, therefore, reducing the connection resistance between the source/drain feature and the source/drain contact features. In some embodiments, the emerged source/drain features include one or more voids formed within the merged portion.

  • Publication number: 20250048694
    Abstract: A semiconductor device structure, along with methods of forming such, are described. The structure includes a source/drain epitaxial feature disposed over a substrate, and the source/drain epitaxial feature includes about 0.002 atomic percent to about 0.02 atomic percent of aluminum. The structure further includes a first semiconductor layer in contact with the source/drain epitaxial feature and a gate electrode layer disposed over the first semiconductor layer.

  • Patent number: 12106036
    Abstract: A document processing device, a method of processing an image thereof, and a computer program product are disclosed. A set of display area information is preset on the document processing device. When the document processing device receives an input image, a set of reference information corresponding to the input image is obtained. The document processing device adjusts the input image according to the set of display area information and the set of reference information to generate an improved preview image. Because the user does not need to consider the direction in which the document is put into the document processing device, the document processing device directly and automatically generates the preview image that is convenient for the user to view based on the input image, thereby achieving the purpose of improving work efficiency, the convenience in use, and the user experience.
