    • The present invention relates to a manufacturing method of a porous carbon structure using heat treatment in an organic solvent, more specifically a manufacturing method of a porous carbon structure comprising: a step of forming a photoresist layer on a substrate; a step of forming a 3D porous photoresist pattern by irradiating the photoresist layer with 3D optical interference patterns by using a 3D optical interference lithography; a step of heat-treating the 3D porous photoresist pattern in a first organic solvent; and a step of obtaining a porous carbon structure by heating the heat-treated photoresist pattern. The manufacturing method according to the present invention passes through a carbonization process after a heat-treating process on a photoresist pattern in an organic solvent so that a carbon structure can be manufactured without an etching process, and thus, process steps for manufacturing a porous carbon structure are reduced, thereby saving a production time, being economical, and because the heat-treating temperature and time are controlled in an organic solvent, the thickness of the carbon structure can be controlled.

    • 本发明涉及一种在有机溶剂中使用热处理的多孔碳结构体的制造方法,更具体地说,涉及一种多孔碳结构体的制造方法,包括:在基板上形成光致抗蚀剂层的工序; 通过使用3D光学干涉光刻用3D光学干涉图案照射光致抗蚀剂层来形成3D多孔光致抗蚀剂图案的步骤; 在第一有机溶剂中热处理3D多孔光致抗蚀剂图案的步骤; 以及通过加热经热处理的光致抗蚀剂图案获得多孔碳结构的步骤。 根据本发明的制造方法,通过在有机溶剂中的光致抗蚀剂图案上进行热处理之后的碳化处理,使得可以在没有蚀刻工艺的情况下制造碳结构,因此,制造多孔碳的工艺步骤 结构减少,从而节省生产时间,经济,并且由于在有机溶剂中控制热处理温度和时间,因此可以控制碳结构的厚度。 (附图标记)(S100)形成光致抗蚀剂层; (S200)通过用3D光学干涉图案照射光致抗蚀剂层来形成3D多孔光致抗蚀剂图案; (S300)在第一有机溶剂中热处理3D多孔光致抗蚀剂图案; (S400)通过对经热处理的光致抗蚀剂图案进行碳化来获得多孔碳结构
