The answer to this question is yes. People like to talk about how the real issue is economics, not physics, but the inability to make chips much smaller economically is very much a reflection of physical constraints on the processes we're currently using to manufacture chips (particularly the lithographic process), and as of right now there's no clear successor to those processes that's going to enable them to get smaller for cheaper.
