  • Patent number: 11114538
    Abstract: A microelectronic transistor may be fabricated having an airgap spacer formed as a gate sidewall spacer, such that the airgap spacer is positioned between a gate electrode and a source contact and/or a drain contact of the microelectronic transistor. As the dielectric constant of gaseous substances is significantly lower than that of a solid or a semi-solid dielectric material, the airgap spacer may result in minimal capacitive coupling between the gate electrode and the source contact and/or the drain contact, which may reduce circuit delay of the microelectronic transistor.

  • Patent number: 10923574
    Abstract: Techniques are disclosed for forming a transistor with one or more additional spacers, or inner-gate spacers, as referred to herein. The additional spacers may be formed between the gate and original spacers to reduce the parasitic coupling between the gate and the source/drain, for example. In some cases, the additional spacers may include air gaps and/or dielectric material (e.g., low-k dielectric material). In some cases, the gate may include a lower portion, a middle portion, and an upper portion. In some such cases, the lower and upper portions of the gate may be wider between the original spacers than the middle portion of the gate, which may be as a result of the additional spacers being located between the middle portion of the gate and the original spacers. In some such cases, the gate may approximate an I-shape, C-shape, -shape, ?-shape, L-shape, or ?-shape, for example.
