英文摘要A semiconductor device having a plurality of semiconductor laser elements is provided, which is capable of reducing an interval of emission points between the semiconductor laser elements and also capable of preventing heat generated by a semiconductor laser element from affecting other semiconductor elements. A concave portion is formed on a silicon substrate, and a protrusion of a quadrangular truncated pyramidal shape consisting of slanted faces of a (1 1 1) plane, a (1 {overscore (1 1) plane, a ({overscore (1 {overscore (1 1) plane and a ({overscore (1 1 1) plane is formed near the center of the concave portion by using the silicon process. Among these slanted faces, a (1 1 1) outer face and a (1 1 1) inner face are determined to be reflecting mirror surfaces. The semiconductor laser elements respectively are fixed on small protrusions formed on the concave portion, and a photodetector for receiving light beams L1' and L2' returning from an optical disc is disposed on a top face of the protrusion.
