Patent ID: 7439545

Claim:
A semiconductor device comprising: a first depressed portion or opening portion formed in an insulating film; a first electrode which is formed over the insulating film around the first depressed portion or opening portion, which is formed at a bottom surface and a side surface of the first depressed portion or opening portion, and which has a second depressed portion in the first depressed portion or opening portion; a semiconductor layer of a first conductivity type, which is formed over the first electrode and which has a third depressed portion in the second depressed portion; a light-emitting layer which is formed over the semiconductor layer of the first conductivity type and which has a fourth depressed portion in the third depressed portion; a semiconductor layer of a second conductivity type which is formed over the light-emitting layer and which has a fifth depressed portion in the fourth depressed portion; and a second electrode formed over the semiconductor layer of the second conductivity type that has a bottom surface and a side surface of the fifth depressed portion.
