IPC: H01L21/28
Filed: 1993-02-22
Abstract: PURPOSE:To acquire stable contact resistance and to reduce a junction leak current by interposing a polysilicon thin film whose coverage is better than that of barrier metal between a tungsten layer and a silicon substrate. CONSTITUTION:After an n-type diffusion layer 2 is formed on a p-type silicon semiconductor substrate 1, a layer insulation film 3 is formed. A contact hole 4 is shaped to expose the diffusion layer 2 and a polysilicon thin film 5 is formed by using a CVD method to the contact hole 4. It becomes possible to cover an interior of a contact hole properly by the polysilicon thin film. Thereafter, a tungsten film 6 is formed by using the CVD method and a tungsten buried plug 7 is formed by etching back a part excepting the contact hole 4. Thereby, it is possible to acquire a stable contact resistance and to reduce a junction leak current.

Title: Method of asphalt dewaxing using synthetic zeolite
Inventor: MORIYOSHI AKIHIRO
IPC: C10C3/00
Filed: 1988-03-11
Abstract: PURPOSE:To remove wax, unsatd. components present in satd. hydrocarbon, etc., from an asphalt through adsorption and obtain an asphalt having excellent low-temp. properties, by mixing an asphalt heated so as to have a lowered viscosity with synthetic zeolite. CONSTITUTION:Asphalt 1 is heated so as to have a low viscosity. The asphalt is mixed with dried synthetic zeolite 2. The incorporated synthetic zeolite 5 adsorbs wax, unsatd. components present in satd. hydrocarbon, arom. components and water which are contained in the asphalt, and simultaneously performs desulfurization. The synthetic zeolite 5 having some of the components of the asphalt 1 adsorbed thereonto is blended as a component of an aggregate 3 when an asphalt mixture 4 is prepared. Alternatively, the adsorbed material 7 is extracted with a solvent 6, or is desorbed by heating under a high pressure or substituting with a purge gas or a substance having higher adsorbability. The asphalt which has adhered to the surface of the synthetic zeolite is returned to purified asphalt 8. Since the wax, unsatd. components present in satd. hydrocarbon, etc. can be removed from the asphalt as described above, it is possible to prevent oxidation of the asphalt and obtain wax improved in adhesion to an aggregate and low temp. properties.

Title: Antenna receiving and inputting circuit
Inventor: GOMI SHINTAROU
IPC: H04B1/18
Filed: 1981-04-18
Abstract: PURPOSE:To eliminate an interference phenomenon due to an intermodulation disturbing wave, etc., by generating an AGC voltage corresponding to a reception state centering on a reception frequency over a wide range. CONSTITUTION:An AGC voltage is led out of an FETQ1 for high frequency amplification at its drain side and an attenuator composed of diodes D1 and D2 is controlled through a wide-band AGC processing circuit. A resistance R3 provided between the drain of the FETQ1 and a tuning transformer T varies the Q value of the tuning transformer T, and as the resistance R3 is increased more and more, band characteristics become wider and wider. Therefore, AGC operation is adjusted on the basis of the value of the resistance R3. Consequently, even when the band is narrowed down behind an intermediate frequency stage, interference is eliminated by controlling the attenuator in accordance with intensity of a near-by frequency.
