    摘要: The present disclosure describes a layout for stress optimization. The layout includes a substrate, at least two fin field effect transistors (FinFET) cells formed in the substrate, a FinFET fin designed to cross the two FinFET cells, a plurality of gates formed on the substrate, and an isolation unit formed between the first FinFET cell and the second FinFET cell. The two FinFET cells include a first FinFET cell and a second FinFET cell. The FinFET fin includes a positive charge FinFET (Fin PFET) fin and a negative charge FinFET (Fin NFET) fin. The isolation unit isolates the first FinFET cell from the second FinFET cell without breaking the FinFET fin.

    摘要: A method is described which includes providing a semiconductor substrate and forming a trench in the semiconductor substrate. An epitaxy region is grown in the trench. An amorphous layer is deposited overlying the epitaxy region. The semiconductor substrate is then annealed. The anneal may convert a portion of the amorphous layer to crystalline material, as found in the epitaxy region. A chemical mechanical polish (CMP) is then performed, which may remove a portion of the amorphous layer which has not been converted. In an embodiment, the amorphous layer and epitaxy region are germanium and the semiconductor substrate is silicon. The formed crystalline region may be used to form a channel of a p-type device.
