Title: Manufacture of semiconductor device
Inventor: KADOMURA SHINGO
IPC: H01L21/027
Filed: 1991-05-21
Abstract: PURPOSE:To remove a redeposit which is generated during etching of a lower- layer resist layer when patterning a high melting-point metal material layer with a three-layer resist process. CONSTITUTION:When a lower-layer resist lyaer with a non-uniform layer thickness is etched by using a mixed gas of O2/Cl2 in a bit wire machining of SRAM where a second-layer polycide film 9 is subjected to patterning. A high melting- point metal silicide layer 8 is exposed first at a region B with a thin layer thickness and then a compound with a composition consisting of for example WClx and WOxCly is generated. After it is sputtered, it is deposited at a pattern side-wall portion, thus forming a redeposit layer 13. After the second-layer polycide film 8 is subjected to patterning and then an intermediate layer pattern 11 is eliminated by RIE, the redeposit layer 13 can also be simultaneously volatilized and eliminated, thus preventing particle contamination when a lower-layer resist pattern 10a is subjected to ashing while a wafer is being heated at approximately 200 deg.C.

Filed: 1979-11-07
Abstract: PURPOSE: To obtain a screen which prevents the metallic foil from wrinkles and cracks, by sealing and exhausting air between the female mold having the forming surface which is minutely uneven and the metallic foil, and after that, by pressing and forming the metallic foil through the elastic body having the thick center.  
     CONSTITUTION: The metallic foil 1 is placed on the female mold 2 so that its mirror surface side is made to oppose the mold, and the sapce between them is airtighltly sealed by pressing its margin by the holding plate 6. Subsequently, after air has been exhausted from the exhaust port 4, formation is performed by pressing said part by use of the pressing member 9. After that, when the pressing member 9 is raised, since the elastic body 7 is formed as a spherical surface having the thick center, pressure is released gradully from the margin of the elastic body 7, and the elasticity is gradually restored to the original state. Accordingly, the large elasticity restoring force does not occur widthwise in the marginal part of the elastic body, as well, and no wrinkle nor crack does not occur in the metallic foil. After that, after the pressing member 9 has been removed, rapid cured resin is applied on the surface of the metallic foil 1, is hardened, and subsequently the metallic foil 1 is separated from the female mold 2 by releasing the vacuum and blowing in air from the exhaust port 4.

IPC: G09G5/20
Filed: 1989-06-07
Abstract: PURPOSE: To simplify constitution by setting each selected real intensity value to be the prescribed neighboring function of a command intensity value including a selected intensity value corresponding to the selected real intensity value. CONSTITUTION: A graphic engine 16 connected with a main processor 12 receives data of a text and a graphic shown on a display 14 and generates at least the intensity value of each pixel within the display 14 in a parameter. These are called command intensity values and stored in a memory 18 connected with the graphic engine 16. As the graphic engine 16 does not give a dot flare, the command intensity value is for a 'logical' pixel. Consequently the command intensity value stored within the memory 18 corresponds to the logical pixel by 1:1. Therefore the real intensity value of a pair of real intensity values of a pixel within a digitized display is calculated from a pair of command intensity values to attain by the standard and least constitution elements.

IPC: H01L21/76
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method whereby if an oxidation preventing film (liner) on trench inner walls is formed thick, no groove is formed at the edges of a trench isolation structure (TI) to ensure a stable profile of the TI structure. SOLUTION: After forming trenches 1, a first oxidation preventing film 104 is isotropically etched for a specified thickness to make the opening diameter of the first oxidation preventing film 104 wider than the trench aperture and form flanges (steps) around the openings of the trenches. If a second oxide preventing film 108 is formed thereon, its portions above the flanges exist in parallel to the substrate surface as a buffer whereby if the buffer parts are cut when the first oxide preventing film 104 is removed, no recess like a groove in the prior art never appears and hence a satisfactory oxidation preventing effect is obtained by thickening the second oxidation preventing film 108.
