Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a low-resistance tungsten film and such a structure where a gate electrode and a source/drain area can be formed through two resist exposure steps, in a gate electrode of a MOSFET having tungsten film. SOLUTION: In the formation process of a MOSFET, an element isolation region 2, a gate insulation film 3 and a gate polysilicon film 4 are formed successively on a silicon substrate 1, and then a titanium nitride film 5 is formed thereon. Further, the titanium nitride film 5 is recrystalized, so that a tungsten film 6 to be formed thereon is made to be at low resistance. Next, in the formation process of a CMOS, the region 2, film 3, film 4 of <=0.35μm in width on the film 3, film 5 of <=0.35μm in width and of <10nm in film thickness on the film 4, and film 6 of <=0.35μm in width on the film 5 are formed on the substrate 1.  Thanks to such a structure, a gate electrode and a source/drain region can be formed by performing resist exposure step twice, ion implantation and heat treatment, and at the same time, such a structure where no mutual diffusion of impurities in the gate electrode is generated can be realized.

Filed: 1990-06-19
Abstract: PURPOSE:To enhance the quality without affecting the dimension of the upper opening, which is to control the focus characteristics, by forming a long circular or square hole in the longer edge side face of an outer cylindrical electrode. CONSTITUTION:A long circular hole 4 is formed in the longitudinally stretching side face 7 of an outer cylindrical electrode 1.

Title: Manufacture of laminated sheet copper-clad on both-sides
Inventor: MISAWA HIDETO
IPC: H05K3/00
Filed: 1993-06-30
Abstract: PURPOSE:To decrease a deflection of a printed wiring board for high-frequency circuit by making the thickness of a copper foil for circuit forming to be laid on the top side to be less than 52% of the thickness of a copper foil for ground ing to be laid on the bottom, in hot molding. CONSTITUTION:A copper foil 1a for circuit forming touches the upper side of a prepreg 4a on the uppermost surface, and a copper foil 1b for grounding touches the lower side of a prepreg 4b at the lowermost surface. The thickness of the copper foil 1a for circuit forming is 52% less than that of the copper foil 1b for grounding. After heat molding, this constitution produces a protrusion on the copper foil side for circuit forming to be laid on the upper side, but when it is used as a high-frequency printed circuit board, upon etching the copper foil 1a for circuit forming, it works to make a deflection of a laminated sheet protrude on the copper foil side for earthling. Forces of equal magnitude are applied to both surfaces in mutually opposite direction, thus diminishing the deflection.

Title: Luminance signal processing circuit
Inventor: ICHIKAWA YUICHI
IPC: H04N5/18
Filed: 1995-06-27
Abstract: PURPOSE: To prevent the fluctuation of clamp potential due to noise by switching the clamp reference voltage of a clamp circuit to the level which is not affected by noise according to the output signal of a DOC circuit detecting the omission of an FM signal. CONSTITUTION: An amplitude limit is performed for the FM luminance signal A from an input terminal 7 by a limitter 8 and the base band luminance signal demodulated by an FM demodulator 9 is inputted in the input terminal 1 of a clamp circuit via a circuit 10. Because a DOC (omission compensation) detection circuit 11 outputs a control signal L/H according to the absence/presence of the omission of the signal A, a changeover transistor 13 is turned off/on. Because a DOC circuit 12 does not perform a compensation operation/performs the operation, the clamp potential of a point A becomes a normal clamp operation at the time of a signal L. At the time of a signal H, the voltage of a point B is lowered by the quantity fixed according to a noise level from clamp reference voltage. Thus, the fluctuation of clamp voltage in response to noise is eliminated.

Abstract: PURPOSE:To bond a metallic material to other (non)metallic material with excellent bonding strength, by forming a base metal electrodeposition layer on one surface of a metallic material, expelling hydrogen through reversing of the polarity of the electrodeposition current and conducting bonding to other (non)metallic material with an adhesive. CONSTITUTION:The cathode of a direct current source is connected to one bonding surface of a material made of a pure metal such as At, Ag, Pt, Pd, Rh, Os, Fe, Ni, Ti, Si, Ge or In, or an alloy contg. at least 50wt% aforesaid metal (e.g.: Ag-Pd alloy), while the anode is connected to a base metal such as Sn, Zn, Pb, Cu, Fe, Ni, Al, Cr, Ti, Si or In, thereby conducting electrodeposition to form a at least 0.02mu-thick base metal electrodeposition layer. The polarity of the electrodeposition current is reversed for 2-4sec to allow an electric current to flow the metallic material towards the base metal. This expels hydrogen present in the electrodeposition layer. A polymerization-curable adhesive contg. an acrylic monomer having an alkali-reactive group incorporated therein is applied on the treated bonding surface of the metallic material from which hydrogen has been expelled, followed by bonding to other (non)metallic material.
