Title: Manufacture of semiconductor device
Inventor: INOUE HIROYUKI
IPC: H01L23/522
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To reduce the aspect ratio of a contact hole by patterning a first and a second conductive film so that they may be left over on a diffusion layer on a semi conductor substrate. SOLUTION: A LOCOS oxide film 102, a gate oxide film 103, and a polycrystalline silicon film 104 are formed in this order on a semiconductor substrate 101. After that, a silicon dioxide film 105 is formed by a CVD method. Nextly, phosphor ions are implanted through the gate oxide film 103 to form a low-density impurity diffusion layer 106. Then, arsenide ions are implanted to form a high-density impurity diffusion layer 108. On these impurity layers 106, 108, a first and a second buried conductive layer 109, 113 are formed. After that, photo resist 114 is applied and is processed to the pattern of each of the buried conductive layers 109, 113. By this method, the aspect ratio of a contact hole 120 can be reduced.

Title: Manufacture of cell and cell
Inventor: SAMURA TETSUYA
IPC: H01M2/08
Filed: 1989-07-28
Abstract: PURPOSE:To manufacture a cell with such good cell characteristics as high conductivity and freedom from liquid spill by filling the portion between both electrodes materials of a cell with electrolyte and the portion other than that portion with light hardening material in case of a cell constituted of both electrode materials, separator, current collecting material, electrolyte, etc. CONSTITUTION:Positive electrode material 2, separator 3, negative electrode material 4 and current collecting material 5 are laminated in order in a container 1 where the light with a wavelength of, e.g. 200-700nm passes through, and dipped in an electrolyte. Then, the container 1 is vacuum-degassed through a vent 9 to replace the air in the separator 3 with the electrolyte and seal the vent 9. Thereafter, when the light is irradiated on the surface of lamination at both sides from a light source 6 through the container 1, the electrolyte 7 of a portion against which the light is striken is hardened, and the electrolyte 8 of a portion against which the light is not striken remains unhardened. Resultantly, the light is not transmitted through the portions of the current collecting material 5, the positive electrode material 2, the separator 3 and the negative electrode material 4, so that the electrolyte remains as it is, and as the light strikes against the portions other than them, the electrolyte is hardened. Thereby, it is possible to simply manufacture a cell with high conductivity and also free from liquid spill because the portion between electrode materials is filled with an electrolyte.
