Abstract: A method of manufacturing a semiconductor device includes: forming a trench in an insulating interlayer by etching the insulating interlayer; forming a conductive layer on bottom, side, and upper surfaces of the insulating interlayer where the trench is formed, using a first deposition process, the conductive layer on the bottom surface of the trench being thicker than the conductive layer on the side surface of the trench; forming a sacrificial layer in the trench covering the conductive layer formed on the bottom surface of the trench using a second deposition process different from the first deposition process; selectively removing the conductive layer formed on the upper surface of the insulating interlayer and formed on the side surface of the trench left exposed through the sacrificial layer; and selectively removing the sacrificial layer, to form a conductive line using the conductive layer remaining on the bottom surface of the trench.

Abstract: Provided is a contactless-type metal card with an electromagnetic wave absorption sheet. The contactless-type metal card may include: a metal body sheet made of a metal material; an antenna inlay sheet made of a synthetic resin material with an antenna mounted on one side thereof; an electromagnetic wave absorption sheet disposed between the metal body sheet and the antenna inlay sheet; an IC device for card mounted on the metal body sheet or the antenna inlay sheet and having terminals connected to two ends of the antenna; a first thermal adhesive sheet disposed between the metal body sheet and the electromagnetic wave absorption sheet; and a second thermal adhesive sheet disposed between the electromagnetic wave absorption sheet and the antenna inlay sheet. The electromagnetic wave absorption sheet is preferably formed by mixing a powder of materials having a property of absorbing an electromagnetic wave and a binder.

Abstract: The present invention relates to testis somatic cell-derived pluripotent stem cells, and more particularly, to pluripotent adult stem cells which exhibit a positive immune reaction to both CD34 and CD73 and which are derived from testis somatic cells. The present invention further relates to a method for producing the testis somatic cell-derived pluripotent stem cells, and to a pharmaceutical composition including same for the treatment of erectile dysfunction.

Abstract: Provided are methods for the vitrification of human oocytes, which comprises: (a) placing human oocytes on a transfer instrument; and (b) placing the transfer instrument and the human oocytes directly into a slushed nitrogen (N2 slush), wherein the human oocytes are directly exposed to the N2 slush thereby undergoing vitrification, and wherein the human oocytes are able to live for a period of time after the human oocytes are devitrified.
