  • Publication number: 20240105849
    Abstract: A method for forming a semiconductor structure is provided. The method for forming the semiconductor structure includes forming a fin structure over a substrate in a first direction, forming a first gate stack, a second gate stack and a third gate stack across the fin structure, removing the first gate stack to form a trench, depositing a cutting structure in the trench, and forming a first contact plug between the cutting structure and the second gate stack and a second contact plug between the second gate stack and the third gate stack. The fin structure is cut into two segments by the trench. A first dimension of the first contact plug in the first direction is greater than a second dimension of the second contact plug in the first direction.

  • Publication number: 20240070418
    Abstract: A scanning method for multiple barcodes is applied in an electronic device. The electronic device loads a tag template, and the tag template has a plurality of detection zones each corresponding to a target barcode and a target barcode type. The electronic device captures a tag image with a plurality of barcode patterns to be detected, and each barcode pattern to be detected has coordinate information on an image coordinate system. The electronic device overlays the tag image with the tag template to determine whether each barcode pattern to be detected is located in one of the detection zones. When the barcode pattern to be detected is located in one of the detection zones and matches the corresponding target barcode type, the electronic device reads the barcode pattern to be detected to obtain a read result.

  • Publication number: 20230344170
    Abstract: A connector includes an enclosure having a top wall provided with a fitting and a mounting section; a retaining member including a main body fitted in the fitting section, an extended section extended forward from the main body and having a hook section projected beyond the top wall for retaining a mating female connector thereto, and an elastic section extended rearward from the main body and located in the mounting section; and a linkage assembly holding the retaining member between it and the mounting section and including a first linking member located above the elastic section and a second linking member connected to the first linking member and the enclosure. When the second linking member is pulled, the first linking member is brought to push the elastic section downward, such that the main body, the extended section and the hook section elastically bias downward simultaneously to release the female connector.

  • Publication number: 20230335946
    Abstract: A connector guide device includes an insulation case, a securing case and a fastening member. The insulation case has a front end and a rear end. The front end of the insulation case has a size different from a size of the rear end of the insulation case. The front end of the insulation case can enter an internal space of the securing case. An upper raised block and a lower raised block of the insulation case are respectively plugged into an upper raised block retaining socket and a lower raised block retaining socket of the securing case to assemble the insulation case and the securing case with each other to form a connector. A circuit board passes through and protrudes from the connector. In connection process, the connector guide device provides guiding effect for the circuit board.

  • Patent number: 8917148
    Abstract: A transmission unit with reduced crosstalk signal includes a first conductor group having at least one first conductor surrounded by a first sheath and at least one second conductor surrounded by a second sheath. The first and the second conductor are axially arranged corresponding to one another. The first sheath has a dielectric coefficient higher than that of the second sheath, so that a difference in dielectric property exists between the first and the second conductor to enable reduction of crosstalk occurred during high-speed signal transmission over the transmission unit.

  • Publication number: 20130017712
    Abstract: A signal transmission cable with insulation piercing terminals includes a flat cable having a plurality of conductors, and a plurality of conductive terminals electrically connected to an end of the flat cable. The conductors respectively have a sheathed section, and a bare section located at an end of the sheathed section and having a length ranged between 0.01 mm and 4 mm. The sheathed sections are respectively surrounded by a first sheath before being together surrounded by a second sheath. The conductive terminals respectively include a spring contact and a plurality of piercing sections formed at an end of the spring contact for electrically connecting to the conductors of the flat cable. The bare sections with a defined length can reduce the stub effect on a signal transmitted via the signal transmission cable to achieve better impedance matching and reduced crosstalk interference during digital signal transmission.

  • Publication number: 20090166082
    Abstract: An anti-electromagnetic-interference (anti-EMI) signal transmission flat cable include a plurality of conducting wires; and an insulating sheath being an integrally formed flat and flexible member for longitudinally enclosing a circumferential surface of each of the conducting wires, so that the conducting wires are substantially equally spaced and parallelly arranged in the insulating sheath to isolate from one another. The insulating sheath has an anti-EMI and electrically non-conductive material doped therein, so as to protect the conducting wires against EMI during signal transmission and accordingly, prevent errors in signal transmission via the conducting wires.
