Abstract
In a semiconductor light emitting device having a matrix of a plurality of bumps composed of one n-bump formed on an n-electrode layer and of a large number of p-bumps formed on p-electrode layers, the occurrence of a faulty junction after mounting can be suppressed by placement of the n-bump at center of the bump array, because the position at the center is most resistant to occurrence of stress after the mounting. Employment of such a configuration of bump array increases reliability of mounting thereof while improving uniformity of light emission intensity in the semiconductor light emitting device having an increased size.
