A transistor is referred to as “angled” if a longitudinal axis of an elongated semiconductor structure (e.g., a fin or a nanoribbon) based on which the transistor is built is at an angle other than 0 degrees or 90 degrees with respect to edges of front or back faces of a support structure on/in which the transistor resides, e.g., at an angle between 10 degrees and 80 degrees with respect to at least one of such edges.
