We present a method that makes it possible to deposit and bond micro-elements on an underlying device. In this manner, micro-constructions can be built by the addition of micro-bricks. The elements are fabricated on a flexible substrate covered with a release coating and are subsequently transferred and bonded onto the target device in a collective process. The process works on complex geometries and can accommodate surface defects, while maintaining a tightly controlled geometry. Application to the fabrication of liquid crystal micro-cells is presented.
