    Abstract: A method for producing a semiconductor device may include applying one or more semiconductor components onto a device body where the device body has a substrate and an integrated circuit. The semiconductor component(s) may include an active zone configured to receive radiation. The method may further include transferring a multitude of semiconductor components from a sacrificial wafer to a target wafer with the device bodies still coupled by using a stamp to place them onto said device bodies. The stamp may be pressed onto the semiconductor components to adhere to the semiconductor components to the stamp and transfer them. As soon as the stamp moves in the opposite direction, the semiconductor component(s) may be separated from holding structures by breaking away webs or their projections on the second semiconductor body and leaving a breaking point directly on an outside of the semiconductor component.

    Abstract: In at least one embodiment of the method of operating a laser device (100) having a plurality of laser diodes (1) which can be controlled independently of one another, wherein controlled laser diodes are each operated with an operating current (I), and wherein each laser diode can be operated for a proper operation in a nominal current range (ΔI), a step A) is carried out in which an input current (I_0) or an input voltage (U_0) is applied to the laser device. Furthermore, a step B) is carried out in which a characteristic value is determined that is representative of a number N of laser diodes that can be operated in the respective nominal current range with the input current applied in step A) or with the input voltage applied in step A). If the characteristic value is representative of N≥1, M laser diodes are controlled in a step C) in such a way that the M laser diodes are each operated in the nominal current range, wherein 1≤M≤N is selected.
