Abstract
A semiconductor device has a semiconductor substrate that in turn has a top semiconductor layer portion and a major supporting portion under the top semiconductor layer portion. An interconnect layer is over the semiconductor layer. A memory array is in a portion of the top semiconductor layer portion and a portion of the interconnect layer. The memory is erased by removing at least a portion of the major supporting portion and, after the step of removing, applying light to the memory array from a side opposite the interconnect layer. The result is that the memory array receives light from the backside and is erased.
