摘要： An external noise intrusion prevention device preventing intrusion of external noise into a central conductor of a trunk cable in an up signal frequency band is provided. A first filter circuit 3 letting a signal in frequencies of 54 MHz or higher pass is provided between an input terminal 1 and an output terminal 2. A front filter circuit 4a and a rear filter circuit 4b, which constitute a second filter circuit 4, are provided on both ends of the external noise intrusion prevention device, respectively. A noise elimination circuit 6 formed by cascading two connection transformers 6a and 6b is also provided. The two connection transformers 6a and 6b are connected to each other while being arranged in a line symmetrical manner.

摘要： A stacked film assembly for use as wiring in a semiconductor device having a bottom film (CVD-W film) 33 and a top film (Al alloy film) 12, where the surface roughness (Ra) of the bottom film is less than 100 .ANG. and the crystal orientation of the top film formed on this surface is controlled, a CVD method for the making thereof, and a semiconductor device in which the stacked film assembly is employed. Even when there is no lattice matching of the bottom film and the top film, crystal orientation of the top film can be sufficiently controlled to provide a targeted face ((111) face with aluminum film), and in particular it will be possible to readily form a stacked film assembly having a satisfactory barrier function as well as sufficient EM resistance and with good film formation.
