Title: Diaphragm breakage protection in a reciprocating diaphragm pump
Inventor: MURAKOSHI FUSAO
IPC: F04B43/00
Filed: 2000-11-09
Granted: 2002-11-21
Abstract: A diaphragm pump prevents deformation, breakage, and the like of a diaphragm caused by the diaphragm being pushed strongly against a discharge opening during operation of the diaphragm pump, and that also provides smooth fluid transfer of the pumped fluid. At its extreme discharge position, the diaphragm is blocked from entering the pumped fluid discharge opening by a perforated diaphragm protecting device covering the fluid discharge opening. Selection of the size of openings in the diaphragm protecting device, appropriate for the materials being pumped, allows smooth movement of pumped fluid in the pump through the pumped fluid discharge opening, without interference. In one embodiment, the diaphragm protecting device is a movable perforated plate which is resiliently urged open, and which is pushed closed when the diaphragm reaches its discharge extreme position.

Title: Gas distribution system for a CVD processing chamber
Inventor: ISHIKAWA TETSUYA
IPC: H01L21/469
Filed: 2000-11-15
Granted: 2002-07-21
Abstract: The present invention provides an apparatus for depositing a film on a substrate comprising a processing chamber, a substrate support member disposed within the chamber, a first gas inlet, a second gas inlet, a plasma generator and a gas exhaust. The first gas inlet provides a first gas at a first distance from an interior surface of the chamber, and the second gas inlet provides a second gas at a second distance that is closer than the first distance from the interior surface of the chamber. Thus, the second gas creates a higher partial pressure adjacent the interior surface of the chamber to significantly reduce deposition from the first gas onto the interior surface. The present invention also provides a method for depositing a FSG film on a substrate comprising: introducing first gas through a first gas inlet at a first distance from an interior surface of the chamber, and introducing a second gas through a second gas inlet at a second distance from the interior surface of the chamber, wherein the second gas creates a higher partial pressure adjacent the interior surface of the chamber to prevent deposition from the first gas on the interior surface. Alternatively, the first gas is introduced at a different angle from the second gas with respect to a substrate surface.
