Latest Patents

Ulrich Bommer holds a patent for an "Infrared light emitting diode with grading." This invention relates to a semiconductor arrangement specifically designed for the manufacture of infrared-emitting diodes. The patent describes a first Si-doped GaAlAs layer that contains both an n-conductivity zone and a p-conductivity zone, which is deposited onto an n-doped GaAs semiconductor substrate. The Al content in this layer decreases continuously over its thickness. A second GaAlAs layer is then deposited on the p-conductivity zone of the first layer, with the Al concentration at the barrier surface being greater than that of the first layer. This innovative structure allows for a light guiding effect, enabling emitted radiation to be output preferentially onto sides of the semiconductor array that are oriented vertically or perpendicularly to the substrate. This design eliminates the need to remove the semiconductor substrate during the manufacturing process of infrared-emitting diodes.
