PURPOSE: A manufacturing method of a nano/micro lens mold and a lens using transferring are provided to precisely manufacture a lens mold having a nano/micro structure at a relatively low cost. CONSTITUTION: A manufacturing method for a nano/micro lens mold using transferring includes: a step(S110) of forming a transfer pattern, which is formed of a material activated by or manipulated by a magnetic force, on a substrate part; a step(S120) of transferring the transfer pattern on a buffer part; a step(S130) of preparing a master having a concave recessed part; and a step(S140) of attaching the transfer pattern on the buffer part to the master using the magnetic force in order to manufacture the lens mold. When the transfer pattern is formed, a sacrificial layer is laminated on a base for forming the device layer, and then the transfer pattern is patterned on the sacrificial layer.

PURPOSE: A synchronizer between a roll stamp and a transfer stage is provided to improve a transfer speed by transferring a large nano device and a nano thin film device to a desirable substrate. CONSTITUTION: A roll stamp(1) rotates to transfer a nano thin film. A transfer stage(2) supports a planar substrate with the nano thin film and continuously transfers the nano thin film. A sensing unit measures a shear force generated by contact with the transfer stage. A control unit(5) controls one of the roll stamp and the transfer stage.

PURPOSE: A graphene light emitting device is provided to improve energy efficiency by generating light by using grapheme with low electricity. CONSTITUTION: A hollow(110) passing through a substrate(100) is formed on a substrate. An insulating layer(200) of a membrane shape is formed in the upper side of the substrate. A graphene(300) is laminated on the upper side of the insulating layer. An electrode(400) is formed on both sides of the upper side of the graphene. A power supply device(500) is connected to an electrode and supplies a power source. A polymer layer is placed between the insulating layer and the grapheme. The polymer layer protects the insulating layer.

PURPOSE: An active removable chuck is provided to actively control an adhesive force, thereby shortening transfer time and process time. CONSTITUTION: A device(30) is formed and transferred on and by a transfer substrate(20a). A chuck(10) is positioned on the device. Power is applied to the chuck. If power is applied in the direction in which the fiber of the chuck is aligned, the adhesive force between the chuck and the device increases. The device is transferred to a target substrate(20b) while the device is attached to the chuck. The device is attached/detached by changing the direction of power applied to the chuck.
