Claim Text:
1. A method for manufacturing a sample for microstructural materials diagnostics comprising: detaching a basic structure from a substrate by irradiating the substrate with a laser beam as an high-energy beam so that the detached basic structure comprises a supported structure and a supporting structure, wherein the supported structure is supported by the supporting structure and wherein the supporting structure is configured to be held by a jig, and thinning the supported structure at least in sections by cutting its surface with the laser beam, wherein the thinning of the supported structure is carried out by irradiating the laser beam onto the supported structure in such a way that a boundary area of the incident laser beam grazes the supported structure in a direction parallel to the substrate's plane of the supported structure, wherein the main beam axis of the laser beam is tilted, relative to the substrate's plane of the supported structure, by an angle α≧5° and α≦20°, wherein the thinning of the supported structure is carried out by introducing, due to laser-beam-induced material removal, at least one channel structure(s) into the surface of the supported structure, into at least one of lateral faces and/or of front faces of the supported structure, or into two opposing lateral faces of the supported structure, wherein the longitudinal direction of the channel structure(s) is/are aligned perpendicular to the longitudinal extension of the supported structure, wherein said at least one channel structure(s) has a diameter of 10-20 micrometers, and a centre distance to an adjacent channel structure(s) of 20-50 micrometers.
