Patent EP-0468669-A1 (EP)
Inventor: LENTINE ANTHONY LODOVICO
IPC: G06E1/00
Filed: 1991-07-11
Abstract: An optoelectronic apparatus where information is communicated to and from the apparatus in the optical domain, but where the apparatus includes a transmission gate (151) interposed between successive optoelectronic gates (101, 102) to sequentially convey information internally in the form of electrical, rather than optical, signals. Illustratively, the transmission gate is optoelectronic and comprises two back to back p-i-n photodiodes each including a quantum well region. The first and second optoelectronic gates are S-SEEDs comprising p-i-n photodiodes also each including a quantum well region. The transmission gate is responsive to a first level of an optical control signal ( 109, 119) for substantially blocking current, and to a second level of the optical control signal for substantially passing current. Applicarions of the apparatus include its use in a shift register, 2 x 1 switch, 1 x 2 switch, and an exclusive OR gate.

Abstract: A silicon oxynitride film to be used as an passivation film in a semiconductor device is formed by the chemical vapour deposition of a mixture of a nitrogen containing organic silane gas such as (CH₃)₃SiNHSi(CH₃)₃, (CH₃)₃SiN(C₂H₅)₂, (CH₃)₃SiNHCOCH₃, (CH₃)₂SiN(CH₃)₂ and CH₂=CH-(CH₃)₂SiN(CH₃)₂ and the ozone gas. A semiconductor wafer is placed in a reaction vessel and is heated at a temperature not higher than 450°C. The mixture of the nitrogen containing organic silane gas the ozone gas is introduced into the reaction vessel and the reaction is carried out to form a silicon oxynitride film having the desired composition at a high deposition rate. Since the poisonous mono-silane gas is not utilized, the process can be carried out safely. Further, the reaction is performed at a low temperature not higher than 450°C, the aluminum wiring conductors are not damaged during the chemical vapour deposition. The reaction vessel may be kept at the atmospheric pressure or a pressure higher than the atmospheric pressure. Further, the plasma CVD may be carried out.

Abstract: Une solution d'un précurseur de céramique préparée à partir d'un ou de plusieurs alkoxydes de métal ou acylates de métal est appliquée sur un film céramique ayant une surface irrégulière et formée sur la surface d'un conducteur, de façon à remplir les vides dans la surface, puis à les chauffer de façon à former une céramique au moins partiellement. Grâce à ce revêtement, la surface de l'isolant est aplanie et l'isolant est ainsi préservé des défauts que comportent les isolants en céramique traditionnels qui s'usent facilement par frottement et qui ont une médiocre aptitude au façonnage. La tendance de cet isolant à dégager des gaz est également réduite.

Abstract: A seal device of the non-contact type having seal faces (4a, 5a) formed by those end faces of a rotating seal ring (5) and a stationary ring (4) which are perpendicular to axes of the rings (5) and (4), and also having dynamic pressure generating spiral grooves (19) formed in one of the seal faces (4a, 5a) at a certain interval in the circumferential direction of the seal face and further having inverted grooves (20) each being formed continuous from the front end of each of the spiral grooves, extending along the circumferential direction of the seal face but across its corresponding spiral groove, and provided with a closed front end. The seal device can be used at high speed and under high pressure and it can correct the tilting of its seal faces (4a, 5a), which is caused by pressure and heat added, to prevent them from being contacted with each other. Even when the difference of pressures added to them changes, the seal device can keep them parallel to each other to reduce the amount of liquid leaked to a greater extent.
