Abstract
Semiconductor components which have a plurality of layers lying on top of one another are manufactured with the assistance of a method for light-induced, photolytic deposition. Particularly, periodically alternating layers (hyperfine structure elements) and/or doping patterns are produced simultaneously with deposition of layers and/or with randomly selected doping gradients. In particular, the method is also suited for simultaneous deposition of layers lying laterally side-by-side or of laterally side-by-side differing dopings of a layer being deposited. In the context of doping, the radiation damage known from implantation is avoided.
