Abstract: In an exemplary embodiment, a method for fabricating integrated circuits includes providing a semiconductor substrate. The method etches the semiconductor substrate to form a non-planar transistor structure having sidewalls. On a standard (100) <110> substrate the fin sidewalls have (110) surface plane if the fins are aligned or perpendicular with the <110> wafer notch. The method includes depositing a sacrificial liner along the sidewalls of the non-planar transistor structure. Further, a confining material is deposited overlying the semiconductor substrate and adjacent the sacrificial liner. The method includes removing at least a portion of the sacrificial liner and forming a void between the sidewalls of the non-planar transistor structure and the confining material. A cladding layer is epitaxially grown in the void. Since the sidewall growth is limited by the confining material, a cladding layer of uniform thickness is enabled on fins with (110) sidewall and (100) top surface.
