Method of manufacturing a semiconductor component, in particular a buried ridge laser

摘要

In the method, a doped semiconductor coating is to be deposited on a disturbed surface (S) of a semiconductor base (9) doped with a dopant having the same conductivity type as the coating. According to the invention, prior to depositing a main layer (28) of the coating (10), a superdoped layer (24) is deposited, which superdoped layer has a dopant concentration that is greater than twice the mean concentration of the coating. The invention applies in particular to manufacturing a semiconductor laser for an optical fiber telecommunications system.
