    Abstract: A semiconductor fin includes a channel region. A gate-stressor member, formed of a metal, extends transverse to the fin and includes gate surfaces that straddle the fin in the channel region. The gate-stressor member has a configuration that includes a partial cut spaced from the fin by a cut distance. The configuration causes, through the gate surfaces, a transverse stress in the fin, having a magnitude that corresponds to the cut distance. Transverse stressor members, formed of a metal, straddle the fin at regions outside of the channel region and cause, at the regions outside of the channel region, additional transverse stresses in the fin. The magnitude that corresponds to the cut distance, in combination with the additional transverse stresses, induces a longitudinal compressive strain in the channel region.

    Abstract: Semiconductor integrated circuits (ICs) employing localized low dielectric constant (low-K) material in inter-layer dielectric (ILD) material for improved speed performance are disclosed. To speed up performance of selected circuits in an IC that would otherwise lower overall speed performance of the IC, low-K dielectric material is employed during IC fabrication. The low-K dielectric material is provided in selected, localized areas of ILD material in which selected circuits are disposed. In this manner, the IC will experience an overall increased speed performance during operation, because circuit components and/or circuit element interconnects of selected circuit(s) that are disposed in the low-K ILD material will experience reduced signal delay. Also, by use of low-K dielectric material in only selected, localized areas of ILD material of selected circuits, mechanical and/or thermal stability concern issues that would arise from use of low-K dielectric material in all of the ILD material in the IC are avoided.

    Abstract: Source/drain contacts between transistor gates with abbreviated inner spacers for improved contact area are disclosed. Related methods of fabricating source/drain contacts and abbreviated inner spacers are also disclosed. Inner spacers formed on sidewalls of the gates of adjacent transistors are abbreviated to reduce an amount of the space the inner spacers occupy on the source/drain region, increasing a critical dimension of the source/drain contact. Abbreviated inner spacers extend from a top of the gate over a portion of the sidewalls to provide leakage current protection but do not fully extend to the semiconductor substrate. As a result, the critical dimension of the source/drain contact can extend from a sidewall on a first gate to a sidewall on a second gate. A source/drain contact formed between gates with abbreviated inner spacers has a greater surface area in contact with the source/drain region providing decreased contact resistance.
