Abstract: PURPOSE: To obtain a semiconductor pressure senser of a stable electrical characteristic and a small zero point variation due to the atmospheric temperature by changing the thickness of an oxide film for passivation of the diaphragm part and constrained part other than the diaphragm part.  
     CONSTITUTION: A diaphragm part 15 on a silicone base plate 12 is tightly sealed by a glass cap 25 for forming a reference pressure chamber 24 such as a vacuum chamber or the like, and the thickness of an oxide film 22 for passivation on piezo resistors 16a and 16b can be made less than 1/3 that of a field oxide film for passivation of the constrained part 13 other than the diaphragm part 15 because its deterioration is prevented by the tight sealing. The passivation film at the part required for electrical insulation is made thick, and the passivation film of the diaphragm 15 having a thermal expansion coefficient greater than that of silicone forming the base plate 12 and being liable to be affected by the temperature, and having a large zero point resistance is made thin. By this construction, a semiconductor pressure senser having an improved zero point temperature characteristic, and small error and small size.

Filed: 1987-02-18
Abstract: PURPOSE:To transmit plural kinds of information without increasing the transmission bit rate by generating plural kinds of synchronizing data having different bit patterns alternatively in response to a 2nd information and sending it together with a 1st information data. CONSTITUTION:In sending a picture information data of a 1st field as the 1st information data, a switch 7 is thrown to the position A by using a field discrimination signal.

IPC: C23C16/42
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent a surface from being damaged due to an attacking gas by introducing a protective gas onto the surface before heating and/or on heating the surface when introducing a first gas and a second gas that reacts with it onto a surface that is heated for depositing a surface. SOLUTION: A semiconductor located at a station 23 is heated to, for example, approximately 440 deg.C and WF6 and SiH4 for depositing tungsten nucleus formation layer are introduced to a semiconductor surface through a gas entrance 30 at the upper part of the station 23. H2 is generated due to the reaction of the both WF6 and SiH4 , and H2 reacts with WF6 , thus generating HF as a by-product. The attacking gas WF6 and HF reach a semiconductor that is newly introduced into a reaction room on a station 21, so that a mixed gas consisting of Ar and silane is introduced to the surface of a semiconductor to protect the semiconductor surface from the attacking gas, thus diluting the attacking gas, adsorbing silane on the semiconductor surface and causing it to react with the attacking gas, thus preventing a surface layer from being damaged.

IPC: H01J43/04
Filed: 1988-02-19
Abstract: PURPOSE:To emit a large quantity of photoelectrons from photoelectric cathode by arranging the photoelectric cathode between a reflecting plate and a light receiving face and arranging the reflecting plate in the direction that the light passing the photoelectric cathode is reflected toward the photoelectric cathode. CONSTITUTION:A photoelectric cathode 17b is provided on the inner face of the main body 17A of a photoelectron multiplier tube to face a slender light receiving face 17a extended in the lengthy direction, a curved reflecting plate 17r is fitted to its inside. Since the reflecting plate 17r is arranged in the direction that the accelerated phosphorescence luminous light 15 passing the photoelectric cathode 17b is reflected toward the photoelectric cathode 17b, photoelectrons E are emitted when the accelerated phosphorescence luminous light 15 is thus reflected and radiates the photoelectric cathode 17b again. The accelerated phosphorescence luminous light 15 passes the photoelectric cathode 17b at least twice, thereby the generation efficiency of photoelectrons can be improved as compared with that when the light passes the photoelectric cathode only once.
