Control of P-contact resistance in a semiconductor light emitting device |
| abstract |
A device according to embodiments of the invention includes a semiconductor device structure ( 10 ) including a light emitting region ( 14 ) disposed between an n-type semiconductor region ( 16 ) and a p-type semiconductor region ( 12 ). A surface of the p-type semiconductor region ( 12 ) perpendicular to a growth direction of the semiconductor device structure ( 10 ) includes a first portion and a second portion. The first portion is less conductive than the second portion. The device further includes a p-contact ( 21 ) disposed on the p-type semiconductor region ( 12 ) and an n-contact ( 26 ) disposed on the n-type semiconductor region ( 16 ). The p-contact ( 21 ) includes a contact metal layer ( 20 ) and a blocking material layer ( 24 ). The blocking material layer ( 24 ) is disposed over the first portion and no blocking material layer ( 24 ) is disposed over the second portion. |
