Title: Method of manufacturing semiconductor wafer
Inventor: HASHII TOMOHIRO
IPC: B24B37/12
Filed: 2001-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor wafer with improved manufacturing yields by grinding the surface of the wafer using a double-head grinder to increase the manufacturing efficiency and reducing a fine surface waviness generated by the grinding process. SOLUTION: After the wafer is sliced, it is subjected to the grinding process using the double-head grinder, double-sided lapping process, and double-sided polishing process. By the grinding process using the double-head grinder, a distorted layer and macro waviness components generated on the surface of the wafer are removed at dicing, and at the same time, the flatness of the wafer is improved. The fine surface waviness generated at the time of grinding using the double-head grinder is removed in the double-sided lapping process conducted after grinding.

Title: Wavelength stabilized laser, module and method of stabilizing wavelength of laser light
Inventor: YOKOYAMA YOSHITAKA
IPC: G02B5/28
Filed: 2001-08-01
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive small-sized wavelength stabilized laser module. SOLUTION: The backwardly emitted light of a semiconductor laser 1 is converted into light rays which are slightly spread from parallel rays through a lens 2. An array-like photodetector having at least two light receiving sections 5 and 6 is set up on the rear side of the laser 1 so that the photodetector receives the light rays. A filter 3 having such a characteristic that its transmittance continuously increases or decreases with respect to the wavelength of the light rays is set up between the lens 2 and photodetector so that all of the light rays 3 passes through the filter 3. At one 5 of the light receiving section 5 and 6, wavelength-nondependent signals are obtained by detecting the outside portion of the light rays and used for stabilizing and controlling the light output of the laser 1.  At the other light receiving section 6, wavelength- dependent signals are obtained by detecting the central portion of the light rays and used for stabilizing and controlling the wavelength of the light rays. Consequently, the oscillation wavelength of the semiconductor laser 1 can be stabilized with high accuracy.
