Title: High-pressure pressure regulator controlling device for vehicle internal combustion engine
Inventor: YAMAMOTO NAOKI
IPC: F02D41/04
Filed: 2000-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent generation of noises inside a cabin due to pressure pulsation while preventing defective operation of a valve element due to biting of a foreign matter or adhesion. SOLUTION: In a high vehicle speed area in which a vehicle speed V is higher than a predetermined vehicle speed V1 or in a high rotation number area in which the number N of an engine revolutions is higher than a predetermined number N1 of revolutions, a high-pressure pressure regulator is driven according to a low-frequency driving pulse signal (steps 5, 6). In this way, the valve element is vibrated greatly, so that removal of the foreign matter or recovery from adhesion can be carried out. Sound due to pressure pulsation is ignorable because it is masked by another mechanical noise or road noise. In a low vehicle speed and low number of revolutions area, a high-frequency driving pulse signal is used, and generation of noise is prevented (steps 5, 7).  If a fuel pressure condition becomes an abnormal one during control based on the high-frequency driving pulse signal, a switch to the low-frequency driving pulse signal is carried out immediately (steps 8, 9, 6).

Title: Method for improving adhesion of barrier layer to hdp- fsg thin films
Inventor: M SAAD HICHEM
IPC: C23C16/34
Filed: 2000-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a method of forming a damascene FSG film having a good adhesion to silicon nitride in the HDP-CVD system. SOLUTION: Silane SiH4, silicon tetrafluoride SiF4, oxygen O2 and argon Ar are used as reactive gases. SiH4 reacts with SiF4 to produce FSG. Ar is introduced to accelerate the gas dissociation, all the four gases are used almost for deposition, and SiH4 is not used during depositing of an interface part of the FSG film. For depositing silicon nitride on the topside of the FSG film, the interface part designates a topmost part, while for depositing the FSG on the topside of silicon nitride, the interface part designates a bottom part. Use of SiH4 together with SiF4 shows the tendency of relaxing the decomposition effect of SiF4 over the most of deposition. By removing SiH4 from the deposition of the interface part of the FSG film, less hydrogen is taken in a film existing at the interface region to improve the adhesion to silicon nitride existing above or below it.
