  • Publication number: 20240170339
    Abstract: In a method of manufacturing a semiconductor device, an n-type source/drain epitaxial layer and a p-type source/drain epitaxial layer respectively formed, a dielectric layer is formed over the n-type source/drain epitaxial layer and the p-type source/drain epitaxial layer, a first opening is formed in the dielectric layer to expose a part of the n-type source/drain epitaxial layer and a second opening is formed in the dielectric layer to expose a part of the p-type source/drain epitaxial layer, and the n-type source/drain epitaxial layer and the p-type source/drain epitaxial layer respectively recessed. A recessing amount of the n-type source/drain epitaxial layer is different from a recessing amount of the p-type source/drain epitaxial layer.

  • Publication number: 20240107414
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

  • Patent number: 11942543
    Abstract: A high-voltage semiconductor device structure is provided. The high-voltage semiconductor device structure includes a semiconductor substrate, a source ring in the semiconductor substrate, and a drain region in the semiconductor substrate. The high-voltage semiconductor device structure also includes a doped ring surrounding sides and a bottom of the source ring and a well region surrounding sides and bottoms of the drain region and the doped ring. The well region has a conductivity type opposite to that of the doped ring. The high-voltage semiconductor device structure further includes a conductor electrically connected to the drain region and extending over and across a periphery of the well region. In addition, the high-voltage semiconductor device structure includes a shielding element ring between the conductor and the semiconductor substrate. The shielding element ring extends over and across the periphery of the well region.

  • Patent number: 8158456
    Abstract: The formation of through silicon vias (TSVs) in an integrated circuit (IC) die or wafer is described in which the TSV is formed in the integration process prior to metallization processing. TSVs may be fabricated with increased aspect ratio, extending deeper in a wafer substrate. The method generally reduces the risk of overly-thinning a wafer substrate in a wafer back-side grinding process typically used to expose and make electrical contacts to the TSVs. By providing deeper TSVs and bonding pads, individual wafers and dies may be bonded directly between the TSVs and bonding pads on an additional wafer.

  • Patent number: 7986416
    Abstract: A size and position detecting system includes a laser sensor and a controller. The laser sensor includes an emitter emitting a laser beam to a receiver. The controller is configured to compute a first time of how long the emitter emits the laser beam and a second time of how long the receiver receives the laser beam when a cutting tool moves along a first direction perpendicular to and coplanar with a straight line connecting the emitter and the receiver. The controller is configured to record a first position of the cutting tool at a moment when the second time is less than the first time, and a second position of the cutting tool when the second time remains changeless for a predetermined amount of time, to determine whether the cutting tool is off-centered according coordinates difference between the first and second positions along the first direction.

  • Publication number: 20090241093
    Abstract: The present invention relates to a method for debugging a programmable logic controller. An invariant logic formula is set up. A program is checked by the invariant logic formula, and if the program satisfies the invariant logic formula, debugging is complete and the process returns to the program checking step. If the program does not satisfy the invariant logic formula, checking is stopped and a warning signal and position or timing of the program error are issued.
