Abstract

A semiconductor radiation source includes at least one semiconductor chip that generates radiation; a controller with one or more switching elements configured for pulsed operation of the semiconductor chip; and at least one capacitor body, wherein the semiconductor chip directly electrically connects in a planar manner to the capacitor body, the controller electrically connects to a side of the semiconductor chip opposite the capacitor body, and the controller, the capacitor body and the semiconductor chip are stacked on top of each other so that the capacitor body is located between the control unit and the semiconductor chip.
