Patent JP-S637651-A (JP)
Title: Manufacture of semiconductor device
Inventor: HAZUKI RIYOUICHI
IPC: H01L21/768
Filed: 1986-06-27
Abstract: PURPOSE:To prevent the generation of microcracks in interlayer insulating films, by setting the thickness of the insulating film at the bottom layer of the interlayer insulating films comprising a three-layer structure at 1/2 or more of the thickness of an interconnection layer. CONSTITUTION:On a silicon substrate 11, a thermal oxide film 12 is formed. After an interconnection layer 13 is formed thereon, an SiO2 film 14 is deposited as the first insulating film. Then, an SOG film 15 is formed on the SiO2 film 14 by rotary application. As a result, when the thickness of the first SiO2 film 14 is set at 1/2 time or more the thickness of the interconnection layer 13, the yield of microcracks can be approximately prevented. Even if the thickness of the interconnection layer 13 is changed, the yield of the microcracks can be mostly prevented when the condition of 1/2 time or more is satisfied. When the materials of the first and second insulating films 14 and 16 and the material of the flattening film 15 are changed, the yield of the microcracks can be mostly prevented when the thickness of the first insulating film 14 is 1/2 time or more the thickness of the interconnection layer 13 as the above described case even if slight change might be found.

Filed: 1995-05-25
Abstract: PURPOSE: To provide a semiconductor laser, which can suppress disturbance of the far-field image of laser beams, by a method wherein the laser beams, which are emitted from the rear end face of the laser, are prevented from being reflected. CONSTITUTION: A semiconductor laser is chiefly constituted of a semiconductor laser chip 1, a light-receiving element 5, a stem 4 and a cap 6. A glass 13 for compression and sealing is arranged in a region is located in the vicinity of the element 5 and is struck with laser beams 10 and 11 which are emitted from the rear end face of the laser, of the stem 4. By this constitution of the laser, when most of the laser beams emitted from the rear end face enter the element 5 and the glass 13, scattered light is never generated because the surface of the element 5 is covered with an antireflection film and the glass 13 also does not reflect the laser beams and stray light is not generated.
