  • Patent number: 6368941
    Abstract: The present invention provides a method of fabricating a STI on a wafer to eliminate the common occurrence of junction leakage in the prior art. The method begins by forming a patterned hard mask on a silicon substrate. The patterned hard mask is a laminated layer comprising a pad oxide and a silicon nitride layer, and exposes a portion of the surface of the silicon substrate. The exposed portion of the silicon substrate is then dry etched to form a trench in the silicon substrate having a <100> surface and a <111> surface. Next, a portion of the pad oxide is wet etched around the STI corners of the trench to expose a portion of the top surface of the silicon substrate surrounding the periphery of the trench. A microwave-excited Kr/O2 plasma is used to oxidize both the interior surface of the trench and the exposed top surface of the silicon substrate located beneath the layer of silicon nitride surrounding the periphery of the trench at a temperature of 400° C.

  • Patent number: 6367026
    Abstract: A method of and apparatus for providing clock signals for synchronizing operation of elements of a digital interface system between an IEEE 1394 serial bus and a personal computer interface (PCI) bus. The digital interface system includes a number of functional elements in addition to a PCI interface element. Each of the functional elements and the PCI interface element receives a system clock signal via a clock tree. The clock tree derives individual clock signals from the system clock and provides these individual clock signals to each of the functional elements. The clock tree is balanced such that each clock transition occurs at each of the functional elements, other than the PCI interface element, at substantially the same time. Clock balancing is achieved through appropriate circuit layout and insertion of delay elements. The clock tree also derives a clock signal for the PCI interface element from the system clock signal.

  • Publication number: 20020037499
    Abstract: The invention relates to a microfabricated device for the rapid detection of DNA, proteins or other molecules associated with a particular disease. The devices and methods of the invention can be used for the simultaneous diagnosis of multiple diseases by detecting molecules (e.g. amounts of molecules), such as polynucleotides (e.g., DNA) or proteins (e.g., antibodies), by measuring the signal of a detectable reporter associated with hybridized polynucleotides or antigen/antibody complex. In the microfabricated device according to the invention, detection of the presence of molecules (i.e., polynucleotides, proteins, or antigen/antibody complexes) are correlated to a hybridization signal from an optically-detectable (e.g. fluorescent) reporter associated with the bound molecules. These hybridization signals can be detected by any suitable means, for example optical, and can be stored for example in a computer as a representation of the presence of a particular gene.

  • Patent number: 6363428
    Abstract: An apparatus for and method of separating protocol header information from content data in an IEEE 1394-1995 serial bus network. A receiving node receives isochronous data packets from a transmitting node via a serial bus. Each packet can include a data portion in addition to protocol header information, although not every packet necessarily includes the data portion. Each incoming packet is loaded into a buffer in the receiver as the packet is being received. The protocol header information is removed and stored in sequence in a first block of memory. This is accomplished by placing an input_more direct memory access (DMA) instruction into a next instruction register and, then, executing the instruction. In addition, the receiver is conditioned for removing the data portion from the buffer by loading an input_last DMA instruction into the next instruction register.
