Abstract: PROBLEM TO BE SOLVED: To decrease the number of photo-processes by merging a storage- electrode contact-hole forming process and a storage-electrode forming process, and to prevent the faulty array of a storage-electrode contact hole and a storage electrode. SOLUTION: A first insulating layer 108 is etched by using second substance layers and conductive-layer spacers 118 formed on a second insulating layer 112 as masks. Consequently, storage-electrode contact holes, second openings, having size relatively smaller than the size of first openings are formed. The first and second openings are filled with second conductive layers 120 such as polysilicon films, and the second conductive layers 120 and the second substance layers are etched to a flattened shape so that the upper surface of the second insulating layer 112 is exposed. When the second insulating layer 112 is removed by wet type etching, etc., self-alignment storage electrodes 122 are formed to the second openings as storage-electrode contact holes.

Title: Manufacture of continuous resin sheet
Inventor: OKADA REISUKE
IPC: B29C39/16
Filed: 1985-04-23
Abstract: PURPOSE:To enable compactness of equipment and efficient manufacturing, by a method wherein at the time of manufacturing of a sheet by making use of a mixture of resin or a monomer with a filler whose specific gravity is different from each other, a mixture extruded through a slit is made to cure while the mixture is being made to run in a vertical direction and the same is unloaded in a horizontal direction. CONSTITUTION:A mixture of a resin filler is extruded through a slit and led to a double belt 2. The same 2 is made to cure by heating and cooling the same while the same is being passed through the belt 2. The cured sheet is bent in a horizontal direction by a roll 3. In this instance, the diameter of the roll 3 is made into a favorable size appropriately according to hardness of the cured sheet. Then even if various treatment is applied to the sheet by a double belt 4 while the sheet is being moved horizontally, it does not happen that the filler is sunk or lifted as the resin has already cured once. A building in which facilities are held can be made low and operation is very easy as the sheet moves in the horizontal direction, by leading the sheet to a horizontal state from a vertical state.
