Abstract: A substrate comprises a base wafer, an insulating layer over the base wafer, and a top semiconductor layer over the insulating layer on a side thereof opposite the base wafer. The insulating layer comprises a charge-confining layer confined on one or both sides with diffusion barrier layers, wherein the charge-confining layer has a density of charges in absolute value higher than 1010 charges/cm2. Alternatively, the insulating layer comprises charge-trapping islands embedded therein, wherein the charge-trapping islands have a total density of charges in absolute value higher than 1010 charges/cm2.
