Title: Method for manufacturing EEPROM
Inventor: PENG NAI-JEN
IPC: H01L27/108
Filed: 1999-10-22
Granted: 2001-12-21
Abstract: A method for manufacturing EEPROM. The foregoing EEPROM has a polysilicon stud connected to the source region and being ""spiked"", which is employed to enhance the F-N tunnel effect at the source region. The manufacturing method comprises following steps: a CVD oxide layer is first formed on the silicon substrate. A source region is then defined by reactive ion etching technology. After that, an undoped polysilicon layer is formed on the source region. The undoped layer is then As-doped in order to dope the impurities into the polysilicon layer. The polysilicon layer is partly removed by back-etching or CMP to make the polysilicon remained lower than the top of the trench. After that, a heat-growth step is performed by wet-oxidization in order to grow an oxide layer on the polysilicon layer. At that time, the top of the polysilicon layer is spiked and the spiked polysilicon stud desired is formed to strengthen the erasing effect in the source region.

Abstract: A wafer polishing head and method for polishing a semiconductor wafer on a polishing pad, and a wafer polished or planarized by the method. The polishing head comprises a housing including an upper portion, a retaining ring having an interior cylindrical surface defining an interior cylindrical pocket sized to carry the wafer and to laterally restrain movement of the wafer when the wafer is moved relative to, and while being polished against, the polishing pad. A wafer subcarrier is attached to the retaining ring by a primary diaphragm and to the housing by a secondary diaphragm. A resilient pneumatic annular sealing bladder is coupled for fluid communication to a first pressurized pneumatic fluid to define a first pneumatic zone and is attached to a first surface of the wafer stop plate adjacent the retaining ring interior cylindrical surface to receive the wafer and to support the wafer at a peripheral edge. The resilient pneumatic annular sealing bladder defines a second pneumatic zone radially interior to the first pneumatic zone and extends between the first surface of the wafer stop plate and the wafer when the wafer is attached to the polishing head during a polishing operation and is coupled for fluid communication to a second pressurized pneumatic fluid. The first surface of the wafer stop plate is not being in contact with a wafer back side surface during polishing of the wafer. The wafer attachment stop plate is operative during non polishing periods to prevent the wafer from flexing excessively from an applied vacuum force used to hold the wafer to the polishing head during wafer loading and unloading operations. The first and pressurized fluids are adjusted to achieve a predetermined polishing pressures over a front side surface of the wafer.

Title: System for collecting and condensing light
Inventor: LOPEZ JOSEPH
IPC: G02B27/10
Filed: 2000-06-30
Granted: 2001-09-21
Abstract: A collecting and condensing system includes a paired reflector set having a first, or collecting, reflector that collects radiation emitted from a radiation source and collimates the collected radiation into parallel beams directed to a portion of a second, or condensing or focusing, reflector which focuses the light onto a target along the common optical axis shared by the two reflectors. An opening is formed in the second reflector to permit the radiation to be transmitted from the source located at the focal point of the first reflector toward the first reflector, and an opening is formed in the first reflector to permit the radiation reflected and focused by the second reflector to be transmitted to a target located at the focal point of the second reflector. A lens having the same common optical axis and the same focal points of the first and second reflectors is positioned between the reflectors to collect and condense radiation that would otherwise be lost through the openings formed in the respective reflectors. The overall system produces essentially unit magnification. In addition, a retro-reflector may be added to increase the overall flux density at the target. Multiple electromagnetic sources and associated paired reflector sets can be cascaded along the common optical axis to increase the brightness at the target.
