    • A mold with a protruding pattern is provided that is pressed into a thin polymer film via an imprinting process. Controlled connections between nanowires and microwires and other lithographically-made elements of electronic circuitry are provided. An imprint stamp is configured to form arrays of approximately parallel nanowires which have (1) micro dimensions in the X direction, (2) nano dimensions and nano spacing in the Y direction, and three or more distinct heights in the Z direction. The stamp thus formed can be used to connect specific individual nanowires to specific microscopic regions of microscopic wires or pads. The protruding pattern in the mold creates recesses in the thin polymer film, so the polymer layer acquires the reverse of the pattern on the mold. After the mold is removed, the film is processed such that the polymer pattern can be transferred on a metal/semiconductor pattern on the substrate.
    • 提供具有突出图案的模具,其通过压印过程被压入薄聚合物膜。 提供了纳米线和微丝之间的控制连接以及电子电路的其它光刻元件。 打印印记被配置成形成大致平行的纳米线的阵列,其具有(1)X方向上的微尺寸,(2)在Y方向上的纳米尺寸和纳米间距,以及Z方向上的三个或更多个不同的高度。 如此形成的印章可以用于将特定的单个纳米线连接到微细线或垫的特定微观区域。 模具中的突出图案在薄聚合物膜中产生凹陷,因此聚合物层获得模具上图案的相反。 在除去模具之后,处理膜,使得聚合物图案可以在基底上的金属/半导体图案上转印。
