Abstract: A high-strength and high-ductility steel sheet having a composition including, by weight, 1.0 to 1.4% C, 5.0 to 9.0% Mn, 2.0 to 8.0% Cr and the balance Fe, and unavoidable impurities. The steel sheet has an austenite structure formed at room temperature, and stacking fault energy is effectively controlled by the addition of Cr and N2. Mechanical twins are formed during the plastic deformation of the steel, thereby leading to high levels of work hardening, tensile strength and workability.

Abstract: A semiconductor device and a manufacturing method thereof are provided. In one embodiment of the manufacturing method of the semiconductor device, a through electrode is formed on a semiconductor die, and a dielectric layer such as a photopolymer is coated on the through electrode to cover the through electrode. Under exposure is performed on the dielectric layer, thereby partially removing the dielectric layer by development. As a result, a top end of the through electrode is exposed to the outside or protrudes through the dielectric layer. The dielectric layer remaining on the top end of the through electrode may be removed by performing a plasma descum process, if needed.

The high manganese nitrogen-containing steel sheet according to the present invention comprises 0.5 to 1.0 wt % of carbon, 10 to 20 wt % of manganese, 0.02 to 0.3 wt % of nitrogen, with a remainder of Fe and unavoidable impurities. The high manganese nitrogen-containing steel sheet according to the present invention produces an austenite phase at room temperature, in which the stacking fault energy is effectively controlled by adding chrome and nitrogen. Accordingly, the high manganese nitrogen-containing steel sheet of the present invention produces a mechanical twin during the plastic deformation of the steel sheet, thereby increasing the work hardening rate, tensile strength, and workability.
