  • Publication number: 20230419010
    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: 20230116581
    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).

  • Publication number: 20200105154
    Abstract: A portable system to enable broad access to micro- and nano-scale technologies. The portable system includes a fabrication module configured to enable creation of a small tech device or structure or to enable demonstration of a small tech process. The portable system further includes a metrology module configured to allow measuring, testing or characterizing a property of the small tech device, structure or process. Furthermore, the portable system includes a quality control module configured to validate results from the metrology module against a set of expected results measured independently. The portable system is used for the design and assembly of a prototype tool with all the functionalities or a subset of functionalities present in a master tool used in a small tech factory.
