Abstract:
The invention relates to a method and a through-vapor mask for depositing layers in a structured manner by means of a specially designed coating mask which has structures that accurately fit into complementary alignment structures of the microsystem wafer to be coated in a structured manner such that the mask and the wafer can be accurately aligned relative to one another. Very precisely defined portions on the microsystem wafer are coated through holes in the coating mask, e.g. by mans of sputtering, CVD, or to evaporation processes.

Abstract:
It is disclosed a method of printing comprising the steps of: providing a solid state material having at least one exposed surface; applying an auxiliary layer to the exposed surface to form a composite structure; subjecting the composite structure to conditions inducing a stress pattern in the auxiliary layer and in the solid state material, thereby facilitating fracture of the solid state material substantially along a plane at a depth therein; and patterning the auxiliary layer after removing the auxiliary layer and, therewith, a layer of the solid state material terminating at the fracture depth.

Abstract:
The present invention relates to nanoprocessing and heterostructuring of silk. It has been shown that few-cycle femtosecond pulses are ideal for controlled nanoprocessing and heterostructuring of silk in air. Two qualitatively different responses, ablation and bulging, were observed for high and low laser fluence, respectively. Using this approach, new classes of silk-based functional topological microstructures and heterostructures which can be optically propelled in air as well as on fluids remotely with good control have been fabricated.
