摘要:
When a 2-dimensional video image is displayed, a front/rear feeling and a stereoscopic feeling are enabled to be expressed. A detection signal Sd is formed by a high pass filter 25 and a rectifying circuit 26 in accordance with an amount of edge information. The detection signal Sd is supplied to a variable delay circuit 14L. A detection signal Sd′ is supplied to a variable delay circuit 14R. The variable delay circuits 14L and 14R are controlled in accordance with the edge information amount so that a video image for the left eye and a video image for the right eye are moved in the opposite directions. Thus, an imaginary image is synthesized to the front or rear side from a display plane. The left and right video images are displayed on CRTs 20L and 20R. The projection light passes through a horizontal polarizing filter 21L and a vertical polarizing filter 21R and the left and right video images are overlapped on a screen 22. The left and right video images are separately observed by glasses 23 having polarizing filters 24L and 24R and a stereoscopic feeling is enhanced.

A first polycide lead, which is formed on a silicon substrate, consists of a first doped polysilicon layer and a first tungsten silicide layer that is formed on the first doped polysilicon layer. An interlayer insulating film, which is formed on the silicon substrate, has an opening that reaches the first doped polysilicon layer. A second polycide lead, which is formed on the interlayer insulating film, consists of a second doped polysilicon layer that is connected to the first polycide lead in the opening and a second tungsten silicide layer that is formed on the second doped polysilicon layer. In the opening, the first and second doped polysilicon layers are in contact with each other at the side surfaces of the first polycide lead.

A semiconductor device having a protective insulating film is disclosed. This semiconductor device includes a semiconductor substrate, and an interconnection pattern provided on said semiconductor substrate and electrically connected with said elements. A silicon-oxy-nitride film is provided on said semiconductor substrate so as to cover said interconnection pattern. The silicon-oxy-nitride film is deposited in accordance with a chemical vapor deposition Method using plasma, using a mixture gas including organic silane and a nitriding gas and has therefore superior step coverage. The silicon-oxy-nitride film has a superior barrier characteristic to moisture coming in from the outside. A semiconductor device superior in reliability such as moisture resistance is thus obtained.

A semiconductor device having a multilayer interconnection structure includes a tungsten plug buried in a contact hole formed in an interlayer insulating film covering first aluminum interconnection with a first titanium film and a first titanium nitride film interposed therebetween, and second aluminum interconnection formed thereon with a second titanium film and a second titanium nitride film interposed therebetween. According to this structure, remaining particles of an alterated layer of aluminum formed on the surface of the first aluminum interconnection are removed, and the first aluminum interconnection reacts with the first titanium film to form an intermetallic compound, so that mixing of the interface between them is carried out. Coverage of the contact hole is improved by burying the tungsten plug.

In a semiconductor device, an impurity diffused layer serving as an active region is formed in a predetermined region of the surface of a semiconductor substrate of silicon, an underlayer insulating film is formed on the semiconductor substrate for the purpose of protecting and stabilizing the surface of the semiconductor substrate, and an interconnection electrically connected to the impurity diffused layer through a contact hole and formed on an Al-Si-Sn alloy, an Al-Si-Sb alloy or alloys having Ti added to the respective alloys, so that occurrence of an alloy pit and a silicon nodule is prevented. In addition, a completed protective film is formed on the interconnection and the underlayer insulating film and an aperture in a bonding pad region is formed in a predetermined region of the completed protective film, so that the interconnection and the bonding pad are electrically connected to each other. The proportion of silicon and other materials in the alloy are controlled to simultaneously avoid alloy pit and silicon nodule defects both at the contact hole and throughout the alloy conductor.

A pebble-stone crushing device for use in an excavator for laying pipelines underground has a plurality of rotor teeth formed integrally with the rear face of a cutter head which is mounted in the most front part of an excavator body to excavate a working face in front thereof, and a plurality of stator teeth formed radially on and integrally with an annular front face plate of said excavator body so as to cooperate with said rotor teeth. The stator teeth comprises plural groups of radially spaced apart tooth members having different length. Further, the tooth members comprises groups of comparatively long main tooth members and groups of comparatively short auxiliary tooth members each being disposed, respectively, between every adjacent two main tooth members.
