  • Patent number: 12632634
    Abstract: Various embodiments of the present technology provide for the ultra-high density heterogenous integration, enabled by nano-precise pick-and-place assembly. For example, some embodiments provide for the integration of modular assembly techniques with the use of prefabricated blocks (PFBs). These PFBs can be created on one or more sources wafers. Then using pick-and-place technologies, the PFBs can be selectively arranged on a destination wafer thereby allowing Nanoscale-aligned 3D Stacked Integrated Circuit (N3-SI) and the Microscale Modular Assembled ASIC (M2A2) to be efficiently created. Some embodiments include systems and techniques for the construction of construct semiconductor devices which are arbitrarily larger than the standard photolithography field size of 26×33 mm, using pick-and-place assembly.

  • Publication number: 20260005069
    Abstract: A method for fabricating a three-dimensional (3D) stacked integrated circuit. Pick-and-place strategies are used to stack the source wafers with device layers fabricated using standard two-dimensional (2D) semiconductor fabrication technologies. The source wafers may be stacked in either a sequential or parallel fashion. The stacking may be in a face-to-face, face-to-back, back-to-face or back-to-back fashion. The source wafers that are stacked in a face-to-back, back-to-face or back-to-back fashion may be connected using Through Silicon Vias (TSVs). Alternatively, source wafers that are stacked in a face-to-face fashion may be connected using Inter Layer Vias (ILVs).

  • Patent number: 11881435
    Abstract: A method for fabricating a three-dimensional (3D) static random-access memory (SRAM) architecture using catalyst influenced chemical etching (CICE). Utilizing CICE, semiconductor fins can be etched with no etch taper, smooth sidewalls and no maximum height limitation. CICE enables stacking of as many nanosheet layers a desired and also enables a 3D stacked architecture for SRAM cells. Furthermore, CICE can be used to etch silicon waveguides thereby creating waveguides with smooth sidewalls to improve transmission efficiency and, for photon-based quantum circuits, to eliminate charge fluctuations that may affect photon indistinguishability.
