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.
