Filed: 1992-12-18
Abstract: PURPOSE: To provide a method of manufacturing contact vias (connecting vias) in an integrated circuit, in which the vias having no defect due to the step covering and providing a flat topography. CONSTITUTION: On a first insulation layer 12, a first protective layer is formed and openings 16 are formed through this layer 12 at current-forming regions. A conductive layer 18 is deposited on the protective layer and partly fills up openings 16 to form Al conductive plugs 20. A second protective layer is formed on the plugs and portions of the conductive layer formed on the first protective layer are removed. During the removal of these portions, the second protective layer prevents the conductive plugs from being damaged. Next, the first and second protective layers are removed, while leaving the plugs 20 in the openings of the insulation layer. This enables the formation of conductive contacts by depositing the second conductive layer on the plugs.

Title: Video information processing device and method
Inventor: YONEDA AKI
IPC: H04N19/59
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To eliminate flickering or fluctuations of images caused when frame dropping occurs in an interlace frame processing and the dropped frame is supplemented by copying a frame or field immediately preceding or following the dropped frame. SOLUTION: An interlace frame is converted once into a progressive frame 503 which is processed as an interlace frame 501. Thus, half of the time component of the interlace frame is discarded to prevent flickering of a frame-thinned part. The interlace frame is not always converted into a progressive frame but converted only when frame thinning occurs. As a result, the time component loss can be minimized and also computer resources are saved to deal with similar problems.

Abstract: PURPOSE:To improve the corrosion resistance and the mechanical strength of the lug part of a grid body and the welded part of a strap by specifying the amounts of calcium and tin contained in the grid body consisting of a lead- calcium-tin (Pb-Ca-Sn) alloy. CONSTITUTION:The lug part of a grid body consisting of Pb-Ca-Sn alloy is connected to the grid body by a strap formed of a Pb-Sn alloy, in which 1.0-5.0wt.% of Sn is contained and the remainder is Pb. The amount of calcium contained in the grid body is determined as 0.030-0.065wt.%, while the amount of Sn is specified as 0.5-1.0wt.%, and a Pb-Sn alloy containing 1.0-5.0wt.% of Sn is used for the strap for connecting the lug part of the grid body thereto.
