Title: Method of making alternative to dual gate oxide for MOSFETs
Inventor: TONTI WILLIAM R
IPC: H01L27/088
Filed: 2001-02-20
Granted: 2005-09-11
Abstract: A method for forming depleted conductor regions in MOSFET arrays includes the steps of preparing a substrate, forming a conductor layer on the substrate, implanting a dopant species into the conductor layer, masking portions of the doped conductor layer, and counterdoping unmasked portions of the doped conductor layer to form said depleted conductor regions on the substrate. This method provides an alternative to dual gate oxide for MOSFETS wherein low voltage regions at doped layers are used for support devices and high voltage regions at counterdoped portions are used for memory arrays such as DRAM, EDRAM, SRAM and NVRAM. This method is also applicable for all chips requiring high and low voltage integral device operation.

Title: Distributing digital content
Inventor: CHAN FRED S L
IPC: H04N7/173
Filed: 2001-03-16
Granted: 2003-01-01
Abstract: The method and apparatus for distributing digital content includes a local storage medium, a local digital content reader, a remote digital content enabler, and a transmission medium. The local digital content reader transmits a request signal through the transmission medium to the remote digital content enabler requesting an enabler signal to unlock the digital content stored on the local storage medium. The remote digital content enabler processes the request signal and then transmits the enabler signal back to the local digital content reader. The enabler signal enables the local digital content reader to read at least one of the digital contents stored on the local storage medium.

Abstract: A process for patterning thick film electrically functional patterns using a photosensitive polymer layer. A tacky photosensitive layer is applied onto a substrate surface. The photosensitive layer is imaged with a pattern using actinic radiation, the exposed areas of the photosensitive layer become hardened and non-tacky. A subsequent application of a thick film composition sheet will cause the thick film to adhere to the remaining tacky areas. Upon peeling the sheet, a thick film print pattern will be produced. This step is followed by a processing profile prescribed by the thick film composition used which results in a pattern having electrically functional properties. The invention also extends to a process wherein a thick film composition is recovered from a used sheet.

Title: Fiber reinforced cement composite materials using chemically treated fibers with improved dispersibility
Inventor: LUO CAIDIAN
IPC: C04B20/00
Filed: 2002-03-05
Granted: 2003-09-21
Abstract: A fiber-reinforced building material in one embodiment incorporates cellulose fibers that are chemically treated with a dispersant to impart improved dispersibility to the fibers. The fibers are treated with a dispersant which deactivates the hydroxyl sites of the fiber surfaces and in some cases, making the fiber surface more hydrophobic. The dispersant inhibits the hydroxyl groups on the cellulose fiber surface from bonding with hydroxyl groups of other fibers and hydroxyl groups on the same fiber, thereby significantly reducing inter-fiber and intra-fiber hydrogen bonding. The treated fibers can be readily dispersed and uniformly distributed throughout a mixture without re-clustering or reclumping once the mechanical mixing action stops. The chemically treated fibers with improved dispersibility improve the fiber distribution and reinforcing efficiency, which in turn improves key physical and mechanical properties of the material such as the modulus of rupture, z-direction tensile strength, and toughness, and surface finishes. With improved fiber reinforcing efficiency, less dosage of fiber is needed to achieve the required physical and mechanical properties.
