  • Publication number: 20210305390
    Abstract: The current disclosure describes techniques for forming gate-all-around (“GAA”) devices from stacks of separately formed nanowire semiconductor strips. The separately formed nanowire semiconductor strips are tailored for the respective GAA devices. A trench is formed in a first stack of epitaxy layers to define a space for forming a second stack of epitaxy layers. The trench bottom is modified to have determined or known parameters in the shapes or crystalline facet orientations. The known parameters of the trench bottom are used to select suitable processes to fill the trench bottom with a relatively flat base surface.

  • Patent number: 11114303
    Abstract: In a method, a semiconductor substrate is etched to form a trench, such that the trench defines a channel portion. A hard mask layer is deposited over sidewalls of the channel portion. The semiconductor substrate is anisotropically etched to deepen the trench, such that the deepened trench further defines a base portion under the channel portion and the hard mask layer. The hard mask layer is removed from the sidewalls of the channel portion. The deepened trench is filled with an isolation material. The isolation material is recessed to form an isolation structure, in which the channel portion protrudes from the isolation structure.
