我们展示了集成半导体器件的图案化组装到平面，柔性和弯曲的基板上的基础上的毛细管相互作用，涉及液体焊料。基板呈现图案化的焊料涂覆区域，其在组装期间充当装置的组件的受体，并且在操作期间充当电连接。将组分悬浮于水中并轻轻搅拌。焊料-水界面的自由能的最小化为组装提供了驱动力。113 GaAlAs发光二极管与280微米的芯片尺寸制成一个原型圆柱形显示器。在不到3分钟的时间里，在5平方厘米的面积上组装1500个硅立方体也是可能的，缺陷率接近2%。
We demonstrate the patterned assembly of integrated semiconductor devices onto planar, flexible, and curved substrates on the basis of capillary interactions involving liquid solder. The substrates presented patterned, solder-coated areas that acted both as receptors for the components of the device during its assembly and as electrical connections during its operation. The components were suspended in water and agitated gently. Minimization of the free energy of the solder-water interface provided the driving force for the assembly. One hundred and thirteen GaAlAs light-emitting diodes with a chip size of 280 micrometers were fabricated into a prototype cylindrical display. It was also possible to assemble 1500 silicon cubes, on an area of 5 square centimeters, in less than 3 minutes, with a defect rate of similar to2%.
