Title: Manufacture of semiconductor device
Inventor: KOSHIDA MASAHIKO
IPC: H01L21/28
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent each wiring film from being peeled from each other and a contact resistance from increasing by effectively removing an oxide film which is formed on an interface between the upper and lower wiring layers of a composite wiring structure and a multilayer wiring structure. SOLUTION: After a polycrystal silicon film 12, which is a lower layer wiring film is formed, a water mark and a silicon oxide film 13 such as a natural oxide film are formed on the surface thereof. The silicon oxide film 13 is reduced with a tungsten (W) which is contained in an upper layer wiring film (tungsten) formed in a post-process and acts as a reducing substance to a volatile matter for removal. Specifically, an oxygen atom is removed from the silicon oxide film 13 with a WF6 gas, and sublimated as a volatile WOX. Thereby peeling off of a tungsten 15 and increase of resistance of the entire wiring layer are prevented.

IPC: G01B11/26
Filed: 1990-06-12
Abstract: PURPOSE:To perform wide range measurement with good accuracy by examining parallelism of a measurement surface of an object to be measured with respect to a measurement reference surface by means of measuring parallelism between a reference surface of a reference standard and the object to be measured. CONSTITUTION:A part of input light D from an autocollimator 30 is reflected from a reference surface 4 of a reference standard 40 to be reflection light E, which is to return into the autocollimator 30, while the remaining light passes through the reference standard 40 and hits and is reflected on a measurement surface 52 of an object 50 to be measured and then it becomes reflection light F which is to return into the autocollimator 30. Since the reflection light E and reflection light B are parallel to each other and the reflection light B coincides with reflection light C, a shift between the reflection light E and the reflection light F at this time is equal to a shift between the reflection light C and the reflection light F and also equal to a relative value of parallelism of the measurement surface 52 with respect to a measurement reference surface 51.

Title: Floating lid used in container
Inventor: KOBAYASHI TOSHIKATSU
IPC: B65D90/42
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To bring buoyancy to a floating lid and also to smoothly discharge air residing on a lower layer by laminating the lower layer comprising a water absorbing material and an upper layer comprising a non-water-absorbing material including buoyancy and exposing a whole or a part of a side wall when the lower layer absorbs water. SOLUTION: Since a lower layer 11 of the floating lid 10 is formed of a water absorbing material, it attempts to absorb moisture in a liquid-like substance when in contact with a surface of the substance. Even after the lower layer 11 completes absorbing moisture and has been soaked in the liquid-like substance, since an upper layer 12 of the floating lid 10 is constituted of a non-water-absorbing material including buoyancy, the upper layer 12 itself does not absorb the liquid-like substance but floats on its surface, thereby preventing the entire floating lid 10 from sinking in the liquid-like substance. Since a whole or a part of a side face of the floating lid 10 is exposed, absorption of water of the layer 11 and discharge of air residing inside can be simultaneously and smoothly done until water absorption of the lower layer 11 is completed.

Filed: 1986-07-02
Abstract: PURPOSE:To improve the noise immunity as the entire set by poviding a single tuning characteristic to an optical reception section and eliminating an undesired frequency component at the input stage of an optical signal. CONSTITUTION:A twin-T circuit 29 comprising resistors 23-25 and capacitors 26-28 is used for a pheripheral circuit for a photodiode. An output voltage of an emitter of a transistor (TR) 19 is fed back to a base of a TR 20 whose collector is connected with a photodiode via the twin-T circuit 20. Then the locking quantity of a conversion signal current of the photodiode 1 is controlled by a collector current in response to the signal frequency to control an output signal voltage at the base-emitter of the TR 19 to give the frequency selectivity. In selecting the frequency characteristic of the twin-T circuit 29 as the characteristic of a notch filter, the frequency characteristic of the output 30 is the single tuning characteristic. Thus, the noise immunity is improved and no coil is used, then miniaturization and thick film circuit integration are attained.
