Abstract: The method includes steps for improving gate cut isolation region critical dimension (CD) control. Prior to replacement metal gate (RMG) formation, a first sacrificial gate adjacent to first and second channel regions and made of a first sacrificial material (e.g., polysilicon or amorphous silicon) is replaced with a second sacrificial gate made of a second sacrificial material (e.g., amorphous carbon) that is more selectively and anisotropically etchable. A cut is made, dividing the second sacrificial gate into first and second sections, and the cut is then filled with a dielectric to form the gate cut isolation region. The second sacrificial material ensures that, when an opening in a mask pattern used to form the cut extends over a gate sidewall spacer and interlayer dielectric (ILD) material, recesses are not form within the spacer or ILD. Thus, the CD of the isolation region can be controlled.

Abstract: Methods for producing integrated circuits and integrated circuits produced by such methods are provided. In an exemplary embodiment, a method for producing an integrated circuit includes forming a base dielectric layer overlying a substrate. A sacrificial layer is formed overlying the base dielectric layer, and adjacent conductive components are formed in the sacrificial layer where the adjacent conductive components are physically separated by material of the sacrificial layer. The sacrificial layer is removed such that an air gap is defined between the adjacent conductive components, where the air gap overlies the base dielectric layer. A cap dielectric layer is formed overlying the base dielectric layer and the air gap to enclose the air gap within the integrated circuit.

Abstract: In general, aspects of the present invention relate to approaches for forming a semiconductor device such as a FET with reduced gate stack height variance. Specifically, when a gate stack height variance is detected/identified between a set of gate stacks, a hard mask layer and sets of spacers are removed from the uneven gate stacks leaving behind (among other things) a set of dummy gates. A liner layer and an inter-layer dielectric are formed over the set of dummy gates. The liner layer is then removed from a top surface (or at least a portion thereof) of the set of dummy gates, and the set of dummy gates are then removed. The result is a set of gate regions having less height variance/disparity.
