    • A method of fine-pattern formation in which in forming a pattern, a fine pattern formed in a mold can be transferred to a pattering material in a short time at a low temperature and low pressure and, after the transfer of the fine pattern to the patterning material, the fine pattern formed in the patterning material does not readily deform. The method for fine-pattern formation comprises: a first step in which a mold having a fine structure with recesses/protrusions is pressed against a pattering material comprising a polysilane; a second step in which the patterning material is irradiated with ultraviolet to photooxidize the patterning material; a third in which the pressing of the mold against the patterning material is relieved and the mold is drawn from the pattering material; and a fourth step in which that surface of the patterning material to which the fine pattern has been transferred is irradiated with an oxygen plasma to oxidize the surface.
    • 精细图案形成方法在形成图案时,在模具中形成的精细图案可以在低温低压下在短时间内转印到图案材料,并且在精细图案转印到 图案形成材料中形成的微细图案不容易变形。 精细图案形成方法包括:第一步骤,其中具有凹陷/突起的精细结构的模具被压在包含聚硅烷的图案材料上; 第二步骤,其中图案形成材料被紫外线照射以对图案材料进行光氧化; 第三,其中将模具压靠在图案形成材料上被释放并且模具从图案材料中拉出; 以及第四步骤,其中已经转印有精细图案的图案形成材料的表面用氧等离子体照射以氧化该表面。
