A semiconductor wafer (12) with a thinned central portion (2) has a first side (3) and a second side (4) and at least one reinforcement structure for increasing the radial bending resistance of the semiconductor wafer (12). The reinforcement structure provides at least one passage (10) for a fluid flow between an inner face (9) of said one reinforcement structure towards an outer face (8) of the reinforcement structure. The passages (10) are manufactured in a z-direction coming from above the semiconductor wafer (12) in a direction which is essentially perpendicular to the surface, e.g. to the first side (3), of the semiconductor wafer (12). |
