Abstract
A programmable device includes a semiconductor substrate, a buried insulator, a semiconductor oxide layer and a planarized conductive layer. The buried insulator is disposed in the semiconductor substrate and has a first insulating portion and a second insulating portion connected to each other. The semiconductor oxide layer is at least partially disposed in the semiconductor substrate and contacting with the first insulating portion. The planarized conductive layer at least partially covers the first insulating portion, the second insulating portion and the semiconductor oxide layer, and has a flat surface. There is a first distance between the first insulating portion and the flat surface; there is a second distance between the second insulating portion and the flat surface; and the first distance is smaller than the second distance.
