Filed: 1992-03-06
Abstract: PURPOSE:To reduce the driving loss of a drive source in an oil pump in which a fluid is delivered with its pressure boosted by rotation of a driven and drive rotor by forming in the drive rotor relief passages to be opened when the delivery pressure exceeds a set pressure. CONSTITUTION:When a drive rotor 16 is rotated via an input pulley 33 by an engine or the like, a driven rotor 18 meshing with the drive rotor 16 is rotated and the capacity of each pump space 19-22 is changed in sequence and the pressure of a fluid sucked from a suction port 14 is boosted and then the fluid is delivered from a delivery port 15.

Title: Manufacture of semiconductor element
Inventor: YOSHIMARU MASAKI
IPC: H01L23/522
Filed: 1989-03-03
Abstract: PURPOSE:To decrease Cl concentration in an interlayer insulating film, and prevent the fluctuation of threshold voltage of an element caused by heat treatment, by making a silicon oxide film containing arsenic oxide and phosphorus oxide an interlayer insulating film. CONSTITUTION:After a silicon oxide film 12 is stuck and formed, a silicon oxide film 13 containing arsenic oxide and phosphorus oxide is deposited and formed on the whole surface by CVD method using AsCl3 and PH3 as source gas. In this case, the content of arsenic oxide and the content of phosphorus oxide in the silicon oxide film 13 are 2-20mol% and 2-9mol%, respectively. Since the silicon film containing arsenic oxide and phosphorus oxide is used as an interlayer insulating film in a semiconductor element formed in this manner, even when heat treatment is performed after plasma silicon nitride film formation, the threshold voltage of a parasitic MOS transistor does not fluctuate as compared with the case where a silicon oxide film containing only arsenic oxide is used as an interlayer insulating film.
