ABSTRACT:
A semiconductor light emission device includes at least an n-type semiconductor clad layer, a semiconductor active layer and a p-type semiconductor clad layer formed on a substrate in this order. A stripe portion which determines a light emission region is formed on a part of the p-type clad layer and a p-type capping layer is formed on the stripe portion. A p-side electrode is formed on the p-type capping layer. The p-type capping layer includes a lower capping layer in the form of a stripe overlaid on the stripe portion and an upper capping layer which is formed on the lower capping layer and has an area larger than that of the lower capping layer. The contact area between the p-side electrode and the upper capping layer of the p-type capping layer is larger than that between the upper capping layer and the lower capping layer of the p-type capping layer.
