  • Publication number: 20250096036
    Abstract: A method for selectively depositing graphene on cobalt caps on copper interconnects for dual damascene structures in a back-end-of-line substrate is provided. The method comprises providing a semiconductor substrate comprising a first dielectric layer, the copper interconnect in the first dielectric layer, and the cobalt cap on the copper interconnect, the cobalt cap having an exposed metal surface, wherein the exposed metal surface comprises cobalt, and selectively depositing carbon layer on the exposed metal surface.

  • Patent number: 12224203
    Abstract: Semiconductor devices having air gap spacers that are formed as part of BEOL or MOL layers of the semiconductor devices are provided, as well as methods for fabricating such air gap spacers. For example, a method comprises forming a first metallic structure and a second metallic structure on a substrate, wherein the first and second metallic structures are disposed adjacent to each other with insulating material disposed between the first and second metallic structures. The insulating material is etched to form a space between the first and second metallic structures. A layer of dielectric material is deposited over the first and second metallic structures using a pinch-off deposition process to form an air gap in the space between the first and second metallic structures, wherein a portion of the air gap extends above an upper surface of at least one of the first metallic structure and the second metallic structure.

  • Patent number: 11697839
    Abstract: The present invention relates to a method of identifying a target genomic nucleic acid sequence including hybridizing a set of probes to the target genomic nucleic acid sequence, wherein the set of probes has a unique associated barcode sequence for identification of the target genomic nucleic acid sequence, wherein each probe of the set includes (1) a complementary sequence complementary to a first strand of the target genomic nucleic acid sequence and (2) the associated barcode sequence or a portion of the associated barcode sequence, sequencing the associated barcode sequence from probes hybridized to the target genomic nucleic acid sequence using a fluorescence-based sequencing method, and identifying the target genomic nucleic acid sequence by the sequenced barcode sequence.

  • Patent number: 5347495
    Abstract: A transformer used to connect an electro-acoustic transducer to a transmitter and a receiver in a pulse-echo ranging system has a first winding connected to the transducer, and second and third windings connected in parallel to the transmitter and the receiver. The second winding has back-to-back diodes in series with it, and the third winding has several times more turns than the second winding, so that with high amplitude signals, as during transmission, the diodes conduct and render the second winding effective. With low amplitude signals, as during reception, the diodes isolate the second winding and the third winding acts to provide a relative step-up of the amplitude of the received signals.
