Abstract: A method for manufacturing a semiconductor laser device includes preparing an original substrate having a plurality of semiconductor laser device regions arrayed in a matrix, and a plurality of ridges formed in stripes so as to pass through each of the plurality of semiconductor laser device regions that are aligned in one direction. A scribing process is applied to the original substrate along cutting lines set along boundaries of the plurality of semiconductor laser device regions from a rear surface at an opposite side of a top surface at which the ridges are formed. A blade is applied to the original substrate along each cutting line from the top surface of the original substrate for dividing the original substrate along the cutting line.

Abstract: The stress sensor includes: a magnetic material; a stress applied portion on the magnetic material; a magnet disposed so as to be adjacent to by a magnetic material; a magnetic sensor disposed via the magnetic material so as to be opposed to the stress applied portion, wherein the magnetic sensor detects a magnetic flux emitted from a magnetic domain generated in the magnetic material by a local stress applied to the stress applied portion. The local stress or stress distribution can be detected with a convenience structure, and can obtain a high spatial resolution by using a stress response phenomenon of a single magnetic domain.
