    Abstract: First lithography and etching are carried out on a semiconductor structure to provide a first intermediate semiconductor structure having a first set of surface features corresponding to a first portion of desired fin formation mandrels. Second lithography and etching are carried out on the first intermediate structure, using a second mask, to provide a second intermediate semiconductor structure having a second set of surface features corresponding to a second portion of the mandrels. The second set of surface features are unequally spaced from the first set of surface features and/or the features have different pitch. The fin formation mandrels are formed in the second intermediate semiconductor structure using the first and second sets of surface features; spacer material is deposited over the mandrels and is etched back to form a third intermediate semiconductor structure having a fin pattern. Etching is carried out on same to produce the fin pattern.

  • Patent number: 11921321
    Abstract: Provided are three dimensional, stretchable, optical sensor networks that can localize deformations. The devices described herein are suitable for uses in soft robots to determine the position of external contact, such as touching, and possibly internal deformations that may be caused by actuation. Sensor networks of the present disclosure contain a substrate, such as a 3D lattice, and cores having a cladding, such as air. Light passes through the cores and upon deformation of the substrate, cores may come into contact, allowing light to couple between cores due to frustrated total internal reflection. The resulting changes in intensity in the cores can be used to determine the placement and magnitude of deformation.
