  • Patent number: 11742241
    Abstract: Methods are disclosed that provide improved via profile control by forming atomic layer deposition (ALD) liners to protect side walls of vias during subsequent etch processes. ALD liners can be used for BEOL etch processes as well as for full self-aligned via (FSAV) processes and/or other processes. For one embodiment, ALD liners are used as protection or sacrificial layers for vias to reduce damage during multilayer via or trench etch processes. The ALD liners can also be deposited at different points within process flows, for example, before or after removal of organic planarization layers. The use of ALD liners facilitates shrinking of via critical dimensions (CDs) while still controlling via profiles for various process applications including dual Damascene processes and FSAV processes. In addition, the use of ALD liners improves overall CD control for via or hole formation as well as device yield and reliability.

  • Patent number: 11742451
    Abstract: The embodiments of the present disclosure describe a stressed Ge PD and fabrications techniques for making the same. In one embodiment, a stressor material is deposited underneath an already formed Ge PD. To do so, wafer bonding can be used to bond the wafer containing the Ge PD to a second, handler wafer. Doing so provides support to remove the substrate of the wafer so that a stressor material (e.g., silicon nitride, diamond-like carbon, or silicon-germanium) can be disposed underneath the Ge PD. The stress material induces a stress or strain in the crystal lattice of the Ge which changes its bandgap and improves its responsivity.

  • Patent number: 11626486
    Abstract: A back-gate carbon nanotube field effect transistor (CNFETs) provides: (1) reduced parasitic capacitance, which decreases the energy-delay product (EDP) thus improving the energy efficiency of digital systems (e.g., very-large-scale integrated circuits) and (2) scaling of transistors to smaller technology nodes (e.g., sub-3 nm nodes). An exemplary back-gate CNFET includes a channel. A source and a drain are disposed on a first side of the channel. A gate is disposed on a second side of the channel opposite to the first side. In this manner, the contacted gate pitch (CGP) of the back-gate CNFET may be scaled down without scaling the physical gate length (LG) or contact length (LC). The gate may also overlap with the source and/or the drain in this architecture. In one example, an exemplary CNFET was demonstrated to have a CGP less than 30 nm and 1.6× improvement to EDP compared to top-gate CNFETs.
