  • Patent number: 11222849
    Abstract: Various embodiments of the present disclosure are directed towards an integrated circuit (IC) chip comprising a semiconductor device that is inverted and that overlies a dielectric region inset into a top of a semiconductor substrate. An interconnect structure overlies the semiconductor substrate and the dielectric region and further comprises an intermetal dielectric (IMD) layer. The IMD layer is bonded to the top of the semiconductor substrate and accommodates a pad. A semiconductor layer overlies the interconnect structure, and the semiconductor device is in the semiconductor layer, between the semiconductor layer and the interconnect structure. The semiconductor device comprises a first source/drain electrode overlying the dielectric region and further overlying and electrically coupled to the pad. The dielectric region reduces substrate capacitance to decrease substrate power loss and may, for example, be a cavity or a dielectric layer. A contact extends through the semiconductor layer to the pad.

  • Patent number: 11094575
    Abstract: In some embodiments, the present disclosure relates to a method for bonding a first wafer to a second wafer. The method includes aligning a first wafer with a second wafer, so the first and second wafers are vertically stacked and have substantially planar profiles extending laterally in parallel. The method further includes bringing the first and second wafers into direct contact with each other at an inter-wafer interface. The bringing of the first and second wafers into direct contact includes deforming the first wafer so that the first wafer has a curved profile and that the inter-wafer interface is localized to a center of the first wafer. The second wafer maintains its substantially planar profile throughout the deforming of the first wafer. The method further includes deforming the first wafer and/or the second wafer to gradually expand the inter-wafer interface from the center to an edge of the first wafer.

  • Patent number: 11031369
    Abstract: An apparatus and method is provided for controlling a propagation of a bond wave during semiconductor processing. The apparatus has a first chuck to selectively retain a first workpiece. A second chuck selectively retains a second workpiece. The first and second chucks selectively secure at least a periphery of the respective first workpiece and second workpiece. An air vacuum is circumferentially located in a region between the first chuck and second chuck. The air vacuum is configured to induce a vacuum between the first workpiece and second workpiece to selectively bring the first workpiece and second workpiece together from a propagation point. The air vacuum can be localized air vacuum guns, a vacuum disk, or an air curtain positioned about the periphery of the region between the first chuck and second chuck. The air curtain induces a lower pressure within the region between the first and second chucks.

  • Patent number: 10962878
    Abstract: A method for forming a pellicle apparatus involves forming a device substrate by depositing one or more pellicle layers defined over a base device layer, where a release layer is formed thereover. An adhesive layer is formed over a transparent carrier substrate. The adhesive layer is bonded to the release layer, defining a composite substrate comprised of the device and carrier substrates. The base device layer is removed from the composite structure and a pellicle frame is attached to an outermost one of the pellicle layers. A pellicle region is isolated from a remainder of the composite structure, and an ablation of the release layer is performed through the transparent carrier substrate, defining the pellicle apparatus comprising a pellicle film attached to the pellicle frame. The pellicle apparatus is then from a remaining portion of the composite substrate.
