Patent JP-H05206059-A (JP)
Title: Semiconductor device
Inventor: OTA FUMITO
IPC: H01L21/285
Filed: 1992-01-27
Abstract: PURPOSE:To lighten the formal stress of a high melting point metal by forming a metallic wiring layer once in a region, which includes a contact hole, using sputtering method or the like, and then, stopping the contact hole by the use of the high melting point metal. CONSTITUTION:First, an oxide film 2 is made on a substrate 1, and a contact hole 2 is provided. And, by sputtering method, Al wiring 3 is accumulated on an oxide film 2 which includes the inside of the contact hole 2a and the surface of the substrate. Next, by CVD method, tungsten is grown, and the contact hole 2a is stopped with a W plug 4. Then, with the Al wiring 3 as an etching stopper, etchback is performed, and it is flattened by removing the needless tungsten grown on the Al wiring 3. This way, the W plug 4 never contacts directly with the sidewall of the contact hole 2a, so the impurities at formation of a high melting point metal layer or formal stress never affect the underground, and a contact hole excellent in electric coverage can be obtained.

Title: Semiconductor device
Inventor: SANADA TATSUYUKI
IPC: H01S5/00
Filed: 1982-03-10
Abstract: PURPOSE:To make the height of the surface of both elements agree with each other by  a method wherein a stepwise difference is provided by etching a part of a semiconductor substrate of high resistance, and a high photosemiconductor element is provided on  the lower surface of the stepwise difference, and a normal semiconductor element is provided on the surfaces up and down of the stepwise difference. CONSTITUTION:After the stepwise difference is provided by etching a part of the semi-insulating GaAs substrate 31, a p<+> diffused layer 32 serving as a wiring electrode  layer and a p diffused layer 33 serving as the active layer of an FET are formed. Successively, an SiO2 film 52 is partially adhered, and each semiconductor layer 34-38 constituting the photosemiconductor element of a laser, etc. is grown over the entire  surface. Next, when an etching treatment is performed, the semiconductor layer on the  SiO2 film 52 is selectively etched, since the etching speed thereon is faster than on others, and accordingly each semiconductor layer remains only on the lower surface of  the stepwise difference. Finally, when a stripe electrode 40, a contact layer 41, an FET  source electrode 43, a gate electrode 44 and a drain electrode 42 are formed, the device  is completed. Since the surface of each element becomes approximately the same, it is advantageous for use in a lithography.

IPC: H03F1/02
Filed: 1980-03-26
Abstract: PURPOSE:To share a power circuit and control signal circuit between both stereophonic channel parts, by controlling every instantaneous power voltage according to a signal greater in level. CONSTITUTION:Input signals from input signal sources 1 and 31 for left and right stereophonic channels are detected by full-wave rectifiers 12 and 36 and a signal having a greater absolute level is extracted by logic circuit 37.

Abstract: PURPOSE:To obtain a uniform temperature distribution over the whole of the heat radiating pipe by a method wherein mixed gas of the fuel gas and the air for combustion is fed alternately from each end part of the heat radiating pipe by performing a change-over control and a catalytic combustion is caused using catalytic members. CONSTITUTION:Premixed inflammable mixed gas from a mixer 1 is pressingly sent to the flow paths 7 of a heat radiating pipe 6 through a cross valve 4, passes through the flow paths 7 toward the direction shown by an arrow B while making plural catalytic members A1, A2...Ai, Aj..., An catalyst-burn in order and is exhausted from the pipe line l5a for exhaust of a cross valve 4a. A timer circuit 9 gives a signal to a control circuit 8 after an elapse of a constant time and a switching action of the cross valves 4 and 4a is performed by the control circuit 8. Therefore, the gas in the flow paths of the heat radiating pipe 6 makes a counterflow to the direction shown by an arrow C from the B direction and reaches the side of one end part 6a of the heat radiating pipe while making the catalytic members An, An-1... burn in order. By performing a change-over control in such a way, the surface temperature distribution of the heat radiating pipe 6 can be uniformly formed over the whole region of the heat radiating pipe.

Filed: 1982-03-09
Abstract: PURPOSE:To measure the precise length of a fishing line by detecting the revoluting speed and revoluting direction of a roller turned while being pressed against the thread of a spool by a detecting means consisting of magnets, hole elements, etc. CONSTITUTION:When a fishing device is thrown into the sea, the spool 2 is turned in the direction delivering a fishing line, a rubber roller 14 pressed against the periphery of the fishing line is rotated and a worm wheel 18 is rotated at a speed proportional to the length of the delivered line. In every time when the magnets 19a, 19b arrayed with 180 deg. phase difference are opposed to the  hole elements 20a, 20b having 180 deg.-theta phase difference each other, a pulse is generated. A pulse from the hole element 20a is advanced by theta at its phase from  the pulse of the hole element 20b and a discriminating circuit discriminates that  the spool 2 is rotated in the direction delivering the line 3. A microcomputer processes the signal and the pulse due to line length to display the line length to be momently changed on a display part 7b.

When a given count number (n) is reached (during period-D'), the drive of the space motor 9 is turned OFF. The shuttle head 2 makes an inertic movement and goes into the withdrawing region of the platen 4. After the platen 4 is withdrawn, the shuttle head 2 is stopped after the lapse of a given period of time.

Filed: 1983-03-08
Abstract: PURPOSE:To produce Japanese words with high accuracy by checking and correcting effectively the word endings of inflection having high error frequencies with a KANA (Japanese syllabary) character input and in accordance with the prefixing conditions of attached words. CONSTITUTION:An independent word dictionary collating circuit 3 collates the KANA character strings supplied from each sentence with an independent word dictionary and stores the collated independent words to a candidate word memory 5. When the candidate word is equal to a declinable word, the word ending of inflection is checked 6 for the character string obtained by excluding the candidate words out of the KANA character string. An attached word checking circuit 8 collates the character string obtained by excluding the checked word ending of inflection and the candidate word with an attached word dictionary and at the same time checks the connection conditions between the attached word and the independent word. The word ending of inflection is changed for the KANA character string which is rejected through the checking of the circuit 8, and a clause candidate producing circuit 14 produces the correct KANA character string candidates to send them to a clause display circuit 10 for KANA/ KANJI (Chinese character) conversion. These converted characters are displayed 11.
