  • Publication number: 20240085803
    Abstract: Photolithography overlay errors are a source of patterning defects, which contribute to low wafer yield. An interconnect formation process that employs a patterning photolithography/etch process with self-aligned interconnects is disclosed herein. The interconnection formation process, among other things, improves a photolithography overlay (OVL) margin since alignment is accomplished on a wider pattern. In addition, the patterning photolithography/etch process supports multi-metal gap fill and low-k dielectric formation with voids.

  • Patent number: 8817460
    Abstract: A bracket is used for an electronic device into a frame. The frame includes two opposite wall surfaces and at least one pair of guiding rails disposed on the two wall surfaces. The bracket includes a main connection portion, two main elastic arms, and main engaging posts. The main elastic arms respectively extend from two ends of the main connection portion. The two main elastic arms extend towards the same direction with a clamping space defined between the two main elastic arms for accommodating the electronic device. The main engaging posts are respectively disposed on sides of the two main elastic arms facing each other, so that the main engaging posts extend towards the clamping space for engaging lateral surfaces of the electronic device. The two main elastic arms respectively slide along the two guiding rails, so as to fix the electronic device into the frame.

  • Patent number: 8658052
    Abstract: Disclosed is a method for making a highly thermally conductive composite. At first, paraffin wax is subjected to apparent modification. Expandable graphite is oxidized and organically modified. The modified paraffin wax is melted and mixed with the modified expandable graphite so that the modified expandable graphite is evenly distributed in the modified paraffin wax. With the expandable graphite, which exhibits an excellent heat transfer coefficient, the thermal conductivity of the paraffin wax is improved. The melting and solidifying rates of the paraffin wax are improved.

  • Patent number: 8305898
    Abstract: A system and method for guiding and distributing network load flow is proposed and characterized by providing service-providing equipment with better packet routes to reduce the load flow of a routing device. At least two service-providing devices are connected to enable the routing device to guide the packets sent by a user-end device into the at least two connected service-providing devices for allowing the service provider used by the user to process requested services and thereby reduce the number of times of sending data packets to the routing device. In the case that the subscriber has applied for multiple network services, the packets only need to be requested once with the connected service-providing equipment in order to complete all network services.
