Isolation regions in integrated circuit structures

Abstract:

Disclosed herein are isolation regions in integrated circuit (IC) structures, as well as related methods and components. For example, in some embodiments, an IC component may include: a first region including silicon; a second region including alternating layers of a second material and a third material, wherein the second material includes silicon and germanium, the third material includes silicon, and individual ones of the layers in the second region has a thickness that is less than 3 nanometers; and a third region including alternating layers of the second material and the third material, wherein individual ones of the layers in the third region has a thickness that is greater than 3 nanometers, and the second region is between the first region and the third region.
