The following paper was published here a couple years ago by Daniel Nenni after I posted it on Linkedin. I cannot find the SemiWiki link, so I'm sharing the link to Linkedin.
In short, Moore's Law is an economic prediction based on a forecast of advances in fabrication technology. The problems that arose are fixed costs have increased substantially, variable costs have increased, and defect density has led to lower yields of large die sizes running on advanced fabrication processes. These increases have not offset higher transistor density. You can find my complete evaluation at the following link:
