Abstract: PURPOSE: A phase change memory device, a flexible phase change memory device, and a manufacturing method thereof using insulated nano particles are provided to reduce a reset current by decreasing a contact area between a phase change layer and an electrode. CONSTITUTION: A brush layer(11) is laminated on a substrate(10). The coated brush layer is coated with block copolymer solutions. A coated block copolymer(12) is self-assembled by an annealing process. A specific polymer block(13) is removed among the self-assembled block copolymer by patterning process.

Abstract: PURPOSE: A press die equipped with a blank withdrawing assembly is provided to improve productivity by adjusting an operation of a cylinder for matching a feeding speed of a strip and an operation speed of a press die. CONSTITUTION: A press die has a blank withdrawing assembly for withdrawing a blank(113) to an exterior. The blank withdrawing assembly includes a slider member(131), a cylinder(133), a body and a roller member(132). The slider member(131) has a slider body coupled to an upper frame(120) of the press die and a protrusion(136) detachably coupled to the slider body. The cylinder(133) is coupled to a lower frame(110) of the press die so as to withdraw the blank(113) to the exterior as a rod(115) of the cylinder(133) moves forwards. The body is formed with first and second air feeding lines(135,137) for moving the rod(115) of the cylinder(133) in forward and backward directions. The roller member(132) is hinged to a link member, which is rotatably coupled to the body.
