Abstract
In a method for producing a semiconductor light emitting device: a semiconductor lamination of first and second semiconductor layers having different conductive types is formed; a portion of the semiconductor lamination is removed to expose an area of a surface of the first semiconductor layer; a conductor layer connecting the first and second semiconductor layers is formed; a first electrode is formed on the exposed areas of the first semiconductor layer and a second electrode is formed on an upper surface of the second semiconductor layer; a barrier layer covering at least one of the first and second electrodes is formed; and a connection part in the conductor layer connecting the first and second semiconductor layers is removed.
