Abstract: Techniques are disclosed for forming a transistor with enhanced thermal performance. The enhanced thermal performance can be derived from the inclusion of thermal boost material adjacent to the transistor, where the material can be selected based on the transistor type being formed. In the case of PMOS devices, the adjacent thermal boost material may have a high positive linear coefficient of thermal expansion (CTE) (e.g., greater than 5 ppm/° C. at around 20° C.) and thus expand as operating temperatures increase, thereby inducing compressive strain on the channel region of an adjacent transistor and increasing carrier (e.g., hole) mobility. In the case of NMOS devices, the adjacent thermal boost material may have a negative linear CTE (e.g., less than 0 ppm/° C. at around 20° C.) and thus contract as operating temperatures increase, thereby inducing tensile strain on the channel region of an adjacent transistor and increasing carrier (e.g., electron) mobility.

Abstract: Techniques are disclosed for forming a transistor with one or more additional gate spacers. The additional spacers may be formed between the gate and original gate 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 and an upper portion. In some such cases, the lower portion of the gate may be narrower in width between the original gate spacers than the upper portion of the gate, which may be as a result of the additional spacers being located between the lower portion of the gate and the original gate spacers. In some such cases, the gate may approximate a “T” shape or various derivatives of that shape such as -shape or -shape, for example.

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.

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.
