<P>PROBLEM TO BE SOLVED: To provide an optical semiconductor device which has a high degree of parallelism between an optical element of a semiconductor chip and a translucent member of a lid and thereby achieves accurate detection and emission of light by the optical element. <P>SOLUTION: The optical semiconductor device X includes the semiconductor chip 10 having the optical element 11 for emitting and receiving light, an insulating substrate 20 having a mounting plane 21a to mount the semiconductor chip 10 on, and the lid 30 which includes the translucent member 31 having a translucency and forms a storage space S for storing the semiconductor chip 10 mounted on the mounting plane 21a, together with the insulating substrate 20. The lower end face of the lid 30 abuts against the same plane as the mounting plane 21a of the insulating substrate 20. <P>COPYRIGHT: (C)2007,JPO&INPIT |
