Title: Semiconductor light emitting device and manufacture thereof
Inventor: FUJIWARA HIROYUKI
IPC: H01S5/042
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide the semiconductor light emitting device, which favorably connects an individual electrode with a bonding pad, and has high density and high light emitting efficiency.

Title: Method and system for recording/reproducing recording medium
Inventor: YAMAKAWA AKIO
IPC: G11B7/13
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To read out data from a DVD(digital video disc) and a CD having different thickness of substrate using a single optical pickup. SOLUTION: A CD 10 is irradiated with light through a laser diode 41, a laser light grating 42, a beam splitter 43, and an optical lens 44. A laser light reflected on the CD 10 passes through the optical lens 44 and the beam splitter 43 before impinging on a photodiode 61. Since the substrate is thin and the optical lens 44 has number of aperture NA as high as 0.6 in order to reproduce a DVD recorded with data at high density, it is susceptible to aberration at the time of reading a CD 10. In order to prevent the effect of aberration at the time of reading a CD 10, relatively small and large (3-16μm) light receiving sections are formed such that the photodiode 61 detects only the returning light for NA up to about 0.3 and the light is not detected substantially for high NA.

Title: Forming method for automatic positioning pattern
Inventor: MATSUMOTO MINORU
IPC: H01L21/22
Filed: 1980-03-12
Abstract: PURPOSE:To decrease processes, diminish errors and obtain large difference in stages by a method wherein an element pattern as well as an automatic positioning pattern are made up on an insulating film on a substrate, and the substrate is etched. CONSTITUTION:An SiO2 film 2 is made up on an Si substrate 3, and resist-masks 1 for forming an automatic positioning pattern and an element pattern are each built up to regions I, II. The film 2 is etched, the masks 1 are removed and B is introduced to the Si substrate by BBr3 in a nonoxidizable atmosphere. At the same time, Si is etched by Br, and difference in stages (a) is made up. When thermally treating the substrate, an impurity layer is expanded while Si is also oxidized to form SiO2,  and the difference in stages of Si for positioning further expands to (b). According to this constitution, positioning accuracy is little because the number of man- hour of positioning is few, and large difference in stages is obtained.
