Title: Semiconductor device
Inventor: FUJIWARA YUKO
IPC: H01L23/02
Filed: 1990-11-30
Abstract: PURPOSE:To prevent an extruded void by permitting sealing glass to have a notched part on which a projecting part is formed. CONSTITUTION:Sealing glass 11, which is applied on the circumference of a cap 10, is provided with a notched part 20, when the cap 10 is overlapped on an IC package main body, a through path from the cavity inside through the IC package outside shown by the arrow is formed. On the cavity side of the through path, a projecting part 11a which is projected downward from the cap 10 is formed. The increase of the inner pressure of the cavity 17 caused by heating and pressing is prevented by the through path constituted of a space 25 between the inner wall of the package main body 15 and the projecting part 11a. Then, the glass 11 is melt and the notched part 20 is blocked by pressing as shown. When sealing the cavity 17, the glass 11 flows more into the through path than to the outside by the projecting part 11a and an extruded void is not generated.

Title: Manufacture of distributed feedback laser having spatial change in diffraction grating coupling along length of laser cavity
Inventor: DAUTREMONT-SMITH WILLIAM
IPC: H01S5/12
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To provide a distributed feedback layer which is less in hole burning and chirping. SOLUTION: An epitaxial layer 20 is formed on the main surface of a semiconductor substrate 10 and a pair of silicon dioxide masks 31 and 32 is formed on the substrate 10 so that a fixed interval can be maintained between the masks 31 and 32. The widths of the masks 31 and 32 spatially change. It is effective when the epitaxial layer 20 has a refractive index which is different from that of the substrate 10 at the operating wavelength of a laser. Then the masks 31 and 32 are removed and the layer 20 is etched into stripes. The height of the diffraction grating stripes thus obtained spatially changes along the Y-direction expansion of the masks 31 and 32 and the coupling between the diffractive grating and an active layer also changes similarly. Therefore, a high-performance semiconductor laser can be manufactured by adjusting the light output of the laser.
