Abstract:
A method for the production and formation of semiconductor light emitting diodes comprising the steps of:producing a semiconductor light emitting device having at least one pn-junction and at least one metallization layer; applying an etching mask having a first mask arrangement on one side of the semiconductor device, said arrangement defining covered and open areas of the semiconductor device; applying a carrier on the other side of the semiconductor device; vertically etching the semiconductor material within said open areas from said one side to said carrier; removing said etching mask thereby exposing remaining portions of said semiconductor light emitting device not previously covered by said mask, said remaining portions comprising light emitting diodes; engaging said light emitting diodes with an accommodating device, said device comprising slots arranged to individually receive each of said light emitting diodes; and removing said carrier.
