    • Fin-defining mask structures are formed over a semiconductor material layer having a first semiconductor material and a disposable gate structure is formed thereupon. A gate spacer is formed around the disposable gate structure and physically exposed portions of the fin-defining mask structures are subsequently removed. The semiconductor material layer is recessed employing the disposable gate structure and the gate spacer as an etch mask to form recessed semiconductor material portions. Embedded planar source/drain stressors are formed on the recessed semiconductor material portions by selective deposition of a second semiconductor material having a different lattice constant than the first semiconductor material. After formation of a planarization dielectric layer, the disposable gate structure is removed. A plurality of semiconductor fins are formed employing the fin-defining mask structures as an etch mask. A replacement gate structure is formed on the plurality of semiconductor fins.
    • 翅片限定掩模结构形成在具有第一半导体材料的半导体材料层上,并且在其上形成一次性栅极结构。 在一次性栅极结构周围形成栅极间隔物,随后去除鳍状物限定掩模结构的物理暴露部分。 使用一次性栅极结构和栅极间隔物作为蚀刻掩模来凹入半导体材料层以形成凹入的半导体材料部分。 通过选择性沉积具有与第一半导体材料不同的晶格常数的第二半导体材料,在凹入的半导体材料部分上形成嵌入式平面源极/漏极应力。 在形成平坦化介电层之后,去除一次性栅极结构。 使用鳍状限定掩模结构作为蚀刻掩模形成多个半导体鳍。 在多个半导体鳍片上形成替换栅极结构。
