Abstract: PURPOSE:To obtain a semiconductor device having an insulating film which is deposited on an electrode, that is, a gate and is formed so that an upper part of its film is thicker than that of conventional ones to avoid defective breakdown strength by causing an upper edge part of the electrode to be formed into a smooth projection shape. CONSTITUTION:In the case of a semiconductor device having a three-layer structure; electrode 13 - gate insulating film 12 semiconductor 11, an upper part of the electrode 13 is formed a smooth projection shape. For example, a gate oxide film 12 is formed on the semiconductor substrate 11 and doping is performed by forming a gate polysilicon film 13 on the above film 12. An SiO2 film 14 of a first layer, an Si3N4 film 15, and an SiO2 film 16 of a second layer are allowed to grow and they are etched so that the three-layer structure 17 corresponding to dimensions of the electrode may remain. Once its structure is thermally oxidized, outside gate polysilicon of the structure 17 forms an SiO2 film 18. Then, the SiO2 film 18, polysilicon 13, and the gate oxide film 12 are etched by the use of the three-layer structure 17 as a mask. After that, the Si3N4 film 15 is removed to grow an SiO2 film 19 and then, the SiO2 film 19 is etched by using a resist 20 as a mask.

Title: Connecting method and connecting structure of optical waveguide and optical fiber
Inventor: SEMURA SHIGERU
IPC: G02B6/42
Filed: 1994-06-29
Abstract: PURPOSE:To realize fusion splicing of an optical waveguide and an optical fiber. CONSTITUTION:A projecting shape end 70 of the optical waveguide 100 to be fused to the optical fiber 90 at the end faces to each other is separated from a circumferential clad layer 40 and a substrate 10 and, therefore, the heat diffusion at the time of heating the end face of this projecting shape end 70 is lessened at the time of fusion. As a result, the heat capacity of the projecting shape end 70 decreases and, therefore, the fusion of the end faces of the projecting shape end 70 and the optical fiber 90 to each other by fusing the end face of the projecting shape end 70 is made possible.
