    摘要: A method of fabricating a silicon-on-insulator (SOI) chip having an active layer with a non-uniform thickness. The method includes the steps of providing a substrate; providing a buried oxide layer (BOX) on the substrate; providing an active layer on the BOX layer, the active layer having an initially uniform thickness; dividing the active layer into at least a first and a second tile; and altering the thickness of the active layer in the area of the second tile. The method also includes forming a plurality of partially depleted semiconductor devices from the active layer in the area of a thicker of the first and the second tiles and forming a plurality of fully depleted semiconductor devices from the active layer in the area of a thinner of the first and the second tiles.
