Abstract: A method for forming an antifuse on a substrate is provided, which comprises: forming a first conductive material on the substrate; placing the first conductive material in an electrolytic solution; performing anodic oxidation on the first conductive material to form a nanowire made of the first conductive material and surrounded by a first dielectric material formed during the anodic oxidation and to form the antifuse on the nanowire; and forming a second conductive material on the antifuse to sandwich the antifuse between the first conductive material and the second conductive material.

Abstract: A method of forming low-k interconnect structure is disclosed, which comprises: providing at least one protruding structure on a substrate traversing between a first connection region to a second connection region defined thereon; performing anodic oxidation on the substrate having the protruding structure; forming one or more nanowire interconnect in the protruding structure traversing between the first connection region and the second connection region; the nanowire interconnect being surrounded by a dielectric layer formed during the anodic oxidation.

Abstract: Structures, devices and methods are provided for forming nanowires on a substrate. A first protruding structure is formed on a substrate. The first protruding structure is placed in an electrolytic solution. Anodic oxidation is performed using the substrate as part of an anode electrode. One or more nanowires are formed in the protruding structure. The nanowires are surrounded by a first dielectric material formed during the anodic oxidation.

Abstract: Disclosed is a wafer comprising a first layer of GaSb grown on a GaSb substrate by molecular beam epitaxy (MBE), an oxide layer deposited on the surface of the first layer, and a cap layer deposited on the surface of the oxide layer. The wafer was capped with an arsenic (As) layer after the growth of the first layer. The As layer was removed from the wafer before the oxide layer was deposited on the surface of the first layer. Also disclosed is a method of forming a wafer. The method comprises growing a first layer of GaSb on a GaSb substrate by MBE, capping the wafer with an As layer after the growth of the first layer, removing the As layer from the wafer, depositing an oxide layer on the surface of the first layer, and depositing a cap layer on the surface of the oxide layer.
