Semiconductor chip and method for manufacturing the same

摘要

The semiconductor chip has a p-doped region with a coating layer (18) and a contact layer (21). Two intermediate layers (19,20) are provided between the coating layer and the contact layer. A concentration of material component is changed in such a manner within two intermediate layers that the bandgap varies within intermediate layer within a range. An independent claim is also included for a method of manufacturing a semiconductor chip.
