摘要: A first GaN layer (2) is formed on a substrate (1), mask layer (3) having opening parts (3a) are formed thereon, a second GaN layer (4) is selectively grown in the lateral direction from the opening parts on the mask layer, and further a nitride type compound semiconductor layered part (15) is so laminated as to form a light emitting layer. Recessed parts (3b) are formed in the upper face side of the mask layer. In other words, owing to the recessed parts in the upper face side of the mask layer, the second GaN type compound semiconductor layer (4) is grown as to form approximately parallel gap (3c) between the bottom face of the second GaN type compound semiconductor layer and the mask layer. Further, it is preferable for the mask to be formed in a manner that the opening parts for exposing the seeds are not arranged only continuous in one single direction in the entire surface of the wafer type substrate. Consequently, a nitride type compound semiconductor light emitting device can be obtained while being provided with a low dislocation density and excellent light emitting efficiency and especially a semiconductor laser with a lowered threshold current value can be obtained.

摘要: A batch type data input and output control system executes a file output program which outputs data to a file stored in an external storage unit from a main storage apparatus, and a file input program for processing the data in the file. An input/output parallel management means for managing parallel processing of the file output program and file input program and a data transfer unit are provided for transferring the data within the main storage unit without transferring the data through the external storage unit. The data written by the file output program is directly transmitted to the file input program, for instance in units of a character or record under control of the input/output parallel management means. The file output program and file input program are executed in parallel, and can be registered or deleted by designation of another program or a user. When one of the file output program and the file input program ends in an abnormal state, the other program is compulsorily ended. When both programs end in a normal manner and a subsequent program is designated, the subsequent program is automatically initiated.
