An isolation structure of a semiconductor device is formed by forming a hard mask layer on a semiconductor substrate having active and field regions to expose the field region. The image generator generates an illustration image of a part and installation diagram data in which the part is installed in a unit from three-dimensional model data. The method of arousing the patient from sleep at the onset of a sleep apnea event will decrease or eliminate the occurrence of sleep apnea, arrhythmia, and partial epilepsy over time. The data remap control circuit is configured to cause a remap of each of a plurality of encoded data blocks to avoid storing bits in the failing memory device.
