  • Patent number: 12598810
    Abstract: Techniques are provided herein for forming thin film transistor structures having co-doped semiconductor regions. The addition of insulating dopants can be used to improve the performance, stability, and reliability of the TFT. A given TFT structure within an array of similar TFT structures formed in an interconnect region may include a semiconductor region that is co-doped with one or more additional elements. The doping profile can be tuned to optimize performance, stability, and reliability of the TFT structure. In some embodiments, the doping profile causes an overall reduction in the conductivity of the semiconductor region, leading to a higher threshold voltage. Designing access devices (in, for example, a DRAM architecture) with higher threshold voltages can be beneficial for improving reliability of the memory cell.

  • Patent number: 12588241
    Abstract: Techniques are provided for making asymmetric contacts to improve the performance of thin film transistors (TFT) structures. The asymmetry may be with respect to the area of contact interface with the semiconductor region and/or the depth to which the contacts extend into the semiconductor region. According to some embodiments, the TFT structures are used in memory structures arranged in a two-dimensional array within one or more interconnect layers and stacked in a vertical direction such that multiple tiers of memory structure arrays are formed within the interconnect region. Any of the given TFT structures may include asymmetric contacts, such as two contacts that each have a different contact area to a semiconductor region, and/or that extend to different depths within the semiconductor region. The degree of asymmetry may be tuned during fabrication to modulate certain transistor parameters such as, for example, leakage, capacitance, gate control, channel length, or contact resistance.

  • Patent number: 12490460
    Abstract: Techniques are provided herein for forming transistor devices with reduced parasitic capacitance, such as transistors used in a memory structure. In an example, a given memory structure includes memory cells, with a given memory cell having an access device and a storage device. The access device may include, for example, a thin film transistor (TFT), and the storage device may include a capacitor. Any of the given TFTs may include a dielectric liner extending along sidewalls of the TFT. The TFT includes a recess (e.g., a dimple) that extends laterally inwards toward a midpoint of a semiconductor region of the TFT. The dielectric liner thus also pinches or otherwise extends inward. This pinched-in dielectric liner may reduce parasitic capacitance between the contacts of the TFT and the gate electrode of the TFT. The pinched-in dielectric liner may also protect the contacts from forming too deep into the semiconductor region.
