Title: Filter cleaning head
Inventor: SHTEKELMACHER RUBEN
IPC: B01D29/23
Filed: 2004-12-23
Abstract: A filtering device has a filter element disposed between the inlet and the outlet of the device. The inlet surface of the filter element is prone to clogging by suspended particles, e.g. waste, carried with the incoming raw fluid. The invention provides a cleaning head for the filtering device, comprising a basis and a nozzle movably mounted thereon. The cleaning head basis is mounted on a driving mechanism so that the nozzle can scan the inlet surface parallel thereto, and can clean the inlet surface by means of a backwash flow passing through the filter element into the nozzle under a cleaning pressure differential created by connecting the nozzle to a low-pressure outlet. The nozzle maintains, during scanning, permanent contact with the inlet surface so that lateral flow directly into the nozzle is essentially prevented despite variations of distance between the cleaning head basis and the inlet surface during the scanning.

Title: Plasma film forming method and apparatus therefor

IPC: H01L21/205
Filed: 2005-08-25
Abstract: A plasma film-forming method which comprises providing a purifying chamber (2) packed with a substance having a surface layer exhibiting a hydrophilic property or reducing action between a source (1) for supplying a C5H8 gas and a film-forming treatment section (3) for converting the C5H8 gas so as to have a plasmatic state and forming a fluorine-doped carbon film on a wafer (W), passing a C5H8 gas through the purifying chamber (2) to remove the moisture in the C5H8 gas and introduce the resultant C5H8 gas having a moisture content of, for example, about 20 X 10-9 volume ratio to the film-forming treatment section (3), to form a fluorine-doped carbon film. The above plasma film-forming method allows the reduction of the amount of the water incorporated into the resultant fluorine-doped carbon film to an extremely low level, which results in the decrease of the elimination of fluorine in a subsequent heating step due to the moisture in the resultant film, leading to the higher thermal stability of the film. Specifically, the above method allows the formation of a fluorine-doped carbon film exhibiting excellent thermal stability, by preparing and using a C5H8 gas having a moisture content of 60 X 10-9 volume ratio or less.
