    摘要: Methods of fabricating circuit structures including FinFET structures are provided, including: providing a substrate and a first material having a first threshold voltage above the substrate, and a second material having a second threshold voltage lower than the first threshold voltage above the first material; forming fins having base fin portions formed from the first material and upper fin portions formed from the second material; providing gate structures over the fins to form one or more FinFET structures, wherein the gate structures wrap around at least the upper fin portions and have an operating voltage lower than the first threshold voltage and higher than the second threshold voltage, so that the upper fin portions define a channel size of the one or more FinFET structures. Circuit structures including FinFET structures are also provided, in which the FinFET structures have a uniform channel size defined only by upper fin portions thereof.

    摘要: The present application relates to an optical planarizing layer etch process. Embodiments include forming fins separated by a dielectric layer; forming a recess in the dielectric layer on each side of each fin, each recess being for a metal gate; forming sidewall spacers on each side of each recess; depositing a high-k dielectric liner in each recess and on a top surface of each of the fins; depositing a metal liner over the high-k dielectric layer; depositing a non-conformal organic layer (NCOL) over a top surface of the dielectric layer to pinch-off a top of each recess; depositing an OPL and ARC over the NCOL; etching the OPL, ARC and NCOL over a portion of the dielectric layer and recesses in a first region; and etching the portion of the recesses to remove residual NCOL present at a bottom of each recess of the portion of the recesses.

    摘要: Methods of fabricating fin structures having exposed upper fin portions with a uniform exposure height are disclosed herein. The fabrication methods include providing a substrate with plurality of fins and a dielectric material disposed between and over the plurality of fins, planarizing the dielectric material and the plurality of fins, and uniformly recessing the dielectric material to a pre-selected depth below upper surfaces of the plurality of fins to expose upper fin portions. The exposed upper fin portions, as a result of uniformly recessing the dielectric material, have a uniform exposure height above the recessed dielectric material. A protective film may be provided over the recessed dielectric material and exposed upper fin portions to preserve the uniform exposure height of the upper fin portions. The uniform exposure height of the exposed upper fin portions facilitates subsequent formation of one or more circuit structures above the substrate.
