Highly ordered pattern formation of block copolymers (BCPs) within nanoscale templates is of great interest for generating diverse ordered nanostructures. Here, introduced is a combined methodology of nanotransfer printing (nTP) and BCP self‐assembly to guide the formation of spherical nanodots within a printed crossbar nanotemplate. By successfully accommodating poly(styrene‐b‐dimethylsiloxane) (PS‐b‐PDMS) BCPs in the guiding metallic crossbar nanotemplate (≈30 × 30 nm²), a well‐organized array of single‐domain PDMS spheres (≈10 nm) with a square symmetry is successfully obtained in an extremely short annealing time (<5 s). The self‐consistent field theory simulation results theoretically explain the spontaneous one‐to‐one accommodation of PDMS spheres in the confined area of the crossbar template. This approach can potentially be extended to the many other BCP materials and morphologies to diversify the geometry of self‐assembled BCP and/or transfer‐printed nanopatterns for various types of nanodevice applications.

纳米级纵横制模板中嵌段共聚物微区的单独约束

纳米级模板内嵌段共聚物（BCP）的高度有序的图案形成对于产生各种有序的纳米结构非常重要。本文介绍了一种结合了纳米转移印刷（nTP）和BCP自组装的方法，以指导在印刷的横杆纳米模板中形成球形纳米点。通过成功地将聚（苯乙烯-b-二甲基硅氧烷）（PS- b - PDMS）BCP容纳在导向金属横杆纳米模板中（≈30×30 nm ²），在极短的退火时间内（<5 s）成功获得了具有方对称性的组织良好的单域PDMS球阵列（≈10nm）。自洽场理论仿真结果从理论上解释了横杆模板受限区域中PDMS球的自发一对一适应性。这种方法可以潜在地扩展到许多其他BCP材料和形态，以使自组装BCP和/或转移印刷纳米图案的几何形状多样化，以用于各种类型的纳米设备应用。
