  • Patent number: 11289382
    Abstract: A method of forming a semiconductor structure. A first sacrificial gate is formed on a substrate. A spacer is formed on a sidewall of the first sacrificial gate. In the substrate, adjacent to the first sacrificial gate, a source region and a drain region are formed. A channel region is formed between the source region and the drain region. The first sacrificial gate is removed, and a gate trench is formed on the channel region between the spacers. The substrate is etched via the gate trench, thereby forming a recessed trench between the source region and the drain region, and extending into the substrate. The recessed trench has a hexagonal cross-sectional profile. A stress inducing material layer is then formed in the recessed trench. A channel layer is epitaxially grown on the stress inducing material layer. A gate structure is formed on the channel layer.
