Abstract: This application relates to a method for direct growth of multilayer graphene used as a core layer of a pellicle for extreme ultraviolet lithography. This application also relates to a method for manufacturing the pellicle for extreme ultraviolet lithography by using the multilayer graphene direct growth method. The multilayer graphene direct growth method may include forming few-layer graphene on a silicon nitride substrate, forming a metal catalyst layer on the few-layer graphene, and forming an amorphous carbon layer on the metal catalyst layer. The method may also include directly growing multilayer graphene from the few-layer graphene used as a seed layer by interlayer exchange between the metal catalyst layer and the amorphous carbon layer through heat treatment.

Abstract: A support sink application method for 3D printing heat dissipation analysis is provided. The support sink application method according to an embodiment of the present invention comprises the steps in which: a support sink application system adds a support sink in order to simulate heat dissipation using a support in a state where a support shape is not generated in a 3D model; the support sink application system performs heat dissipation simulation with the support sink added to the 3D model; and the support sink application system adjusts the support sink on the basis of the result of the simulation. Therefore, the convenience of heat dissipation simulation can be improved by introducing the support sink capable of representing heat dissipation by the support with no support shape. In addition, due to dependency reduction caused by a support change, it is not necessary to reanalyze a target model (shape) even when a support is added/moved/deleted, and thus the convenience of heat dissipation simulation can be improved.

Abstract: Provided is a holographic printer using a mechanical shutter having adjustable exposure time and no vibration. The holographic printer according to an embodiment of the present invention comprises: a light source; a modulator for generating a holographic fringe pattern in hogel units; a stage on which a hologram recording medium is placed; a driving part for moving the position of the stage in hogel units; and a shutter for periodically exposing an object light due to the holographic fringe pattern generated by the modulator to the hologram recording medium. The shutter comprises: a rotation plate having formed therein an arc-shaped opening which exposes the object light due to the holographic fringe pattern; and a motor for rotating the rotation plate. Therefore, the exposure period and exposure time of the shutter can be variously adjusted by adjusting the rotational state of the rotation plates having the arc-shaped opening formed therein.
