Abstract: A semiconductor device including: a first silicon layer including a first single crystal silicon layer; first transistors with a single crystal channel and overlaid by a first metal layer; overlaid by a second metal layer; overlaid by a third metal layer; a second level with second transistors and including a metal gate, and then disposed over the third metal layer; the second level is overlaid by a third level with third transistors; and then overlaid by a fourth metal layer; fourth overlaid by a fifth metal layer; parts of the second transistors are made with Atomic Layer Deposition (“ALD”); the fifth metal layer average thickness is greater than the third metal layer average thickness by at least 50%; at least one element within at least one of the second transistors has been processed independently of the third transistors.
