  • Publication number: 20250098276
    Abstract: Methods for forming a semiconductor device structure are described. The method includes forming first and second fin structures over a substrate and forming a dielectric wall between the first and second fin structures. The forming the dielectric wall includes depositing a first dielectric layer between the first and second fin structures, and a seam is formed in the first dielectric layer. The forming the dielectric wall further includes performing an anisotropic etch process to remove a portion of the first dielectric layer to expose the seam, performing an isotropic etch process to enlarge an opening of the seam, and the seam has a ā€œVā€ shaped cross-sectional profile. The forming the dielectric wall further includes depositing a second dielectric layer between the first and second fin structures, and the seam is filled. The method further includes forming shallow trench isolation regions adjacent the first and second fin structures.

  • Publication number: 20250078878
    Abstract: A memory device in an integrated circuit is provided, including an input/output (I/O) circuit, a first memory segment and a second memory segment that separated from the first memory segment in a first direction, a first pair of data lines on a first side of the integrated circuit, extending in the first direction and configured to couple the first memory segment to the I/O circuit, and a second pair of data lines separated from the first pair of data lines in a second direction, different from the first direction, on a second side, opposite to the first side, of the integrated circuit, and configured to couple the second memory segment to the I/O circuit. A first width of the first pair of data lines is different from a second width of the second pair of data lines.

  • Publication number: 20080120181
    Abstract: An advertisement playing and monitoring system uses a remote control system to transmit an advertisement file to an advertisement processing machine. The advertisement processing machine stores the advertisement file in a storage unit and plays the advertisement file on a display unit by an image-processing unit. The advertisement processing machine utilizes the image-processing unit to store the images of the display unit in the storage unit for being viewed by a remote monitoring system. Alternatively, the remote control system plays the advertisement file on the display unit via the advertisement processing machine. The remote monitoring system receives the images of the display unit via the advertisement processing machine.
