Abstract: A method for coating a workpiece by cold gas spraying is carried out using a cold gas spray nozzle which generates a particle jet that is directed onto the surface. Additional energy is introduced into the layer that is being formed by way of an electromagnetic energy source, e.g. a laser, which the energy introduced into the particles by the cold gas spray nozzle also contributes to forming the layer. The cold spraying process can be used flexibly as a result of the additional activation by way of electromagnetic radiation. Moreover, layers having a complicated structure, e.g. strip conductors, can be created with the aid of the laser without further processing. A coating unit includes a generator for electromagnetic radiation in addition to the cold gas spray nozzle and is therefore suitable for carrying out the novel method.

Abstract: A semiconductor wafer (10) is structured such that fine structures (3), such as membranes, bridges or tongues, with a thickness d<<D are formed, wherein D designates the thickness of the semiconductor wafer (10). Then particles of a desired material are applied. A temporal or spatial temperature gradient is generated in the semiconductor wafer (10), e.g. by progressive heating. In such a heating process the fine structures heat up more quickly and become hotter than the remaining wafer because they have a smaller heat capacity per area and cannot carry off heat as quickly. In this manner, the fine structures can be heated to a temperature that allows a sintering of the particles. For coating the semiconductor wafer (10) is brought into a reactor (11). A precursor compound of a metal is provided and fed to the reactor (11), where a reaction takes place during which the metal is transformed to a final compound and is deposited in the form of particles on the semiconductor wafer (10).
