摘要： A method for providing a semiconductor device is described. The method provides a plurality of fins. A first portion of each of the plurality of fins is covered by a mask. A second portion of each of the plurality of fins is exposed by the mask. The method also performs an anneal in a volume-increasing ambient, such as hydrogen, at anneal temperature(s) above one hundred degrees Celsius and not more than six hundred degrees Celsius. The second portion of each of the fins is exposed during the anneal such that the second portion of each of the fins undergoes a volume expansion.

摘要： A CMOS system on chip including a series of partial gate-all-around field effect transistors. Each partial GAA FET includes a fin having a stack of channel regions, source and drain regions on opposite sides of the fin, a dielectric separation region including a dielectric material between first and second channel regions, a gate stack on the fin, and a pair of sidewall spacers on opposite sides of the gate stack. A portion of the dielectric separation region has a length from an outer edge of the dielectric separation region to an inner edge of a respective sidewall spacer. The length of the portion of the dielectric separation region of one of the partial GAA FETs is different than the length of the portion of the dielectric separation region of another one of the partial GAA FETs.

The nFET and the pFET each include a fin including a stack of nanowire-like channel regions and a dielectric separation region extending completely between first and second nanowire-like channel regions of the stack. The nFET and the pFET each also include a source electrode and a drain electrode on opposite sides of the fin, and a gate stack extending along a pair of sidewalls of the stack of nanowire-like channel regions. The gate stack includes a gate dielectric layer and a metal layer on the gate dielectric layer. The metal layer does not extend between the first and second nanowire-like channel regions. The channel heights of the nanowire-like channel regions of the partial GAA nFET and the partial GAA pFET are different.

摘要： Exemplary embodiments provide for fabricating a biaxially strained nanosheet. Aspects of the exemplary embodiments include: growing an epitaxial crystalline initial superlattice having one or more periods, each of the periods comprising at least three layers, an active material layer, a first sacrificial material layer and a second sacrificial material layer, the first and second sacrificial material layers having different material properties; in each of the one or more periods, placing each of the active material layers between the first and second sacrificial material layers, wherein lattice constants of the first and second sacrificial material layers are different than the active material layer and impose biaxial stress in the active material layer; selectively etching away all of the first sacrificial material layers thereby exposing one surface of the active material for additional processing, while the biaxial strain in the active material layers is maintained by the second sacrificial material layers; and selectively etching away all of the second sacrificial material layers thereby exposing a second surface of the active material layers for additional processing.
