  • Publication number: 20080047008
    Abstract: An improved deep packet filter system designed to optimize search of dynamic patterns for a high speed network traffic. The improved deep packet filter system is a hardware-based system with optimized logic area. One optimization technique is the sharing of common sub-logic in the hardware design to reduce the number of gates that are required. Another optimization technique is the use of a built-in memory to store portions of the pattern set, also resulting in a reduction of gates. The reduction of the logic area allows the deep packet filter system to be implemented onto a single field-programmable array chip.

  • Publication number: 20080038891
    Abstract: Provided are high voltage metal oxide semiconductor field effect transistor (HVMOSFET) having a Si/SiGe heterojunction structure and method of manufacturing the same. In this method, a substrate on which a Si layer, a relaxed SiGe epitaxial layer, a SiGe epitaxial layer, and a Si epitaxial layer are stacked or a substrate on which a Si layer having a well region, a SiGe epitaxial layer, and a Si epitaxial layer are stacked is formed. For the device having the heterojunction structure, the number of conduction carriers through a potential well and the mobility of the carriers increase to reduce an on resistance, thus increasing saturation current. Also, an intensity of vertical electric field decreases so that a breakdown voltage can be maintained at a very high level. Further, a reduction in vertical electric field due to the heterojunction structure leads to a gain in transconductance (Gm), with the results that a hot electron effect is inhibited and the reliability of the device is enhanced.

  • Publication number: 20070227980
    Abstract: The present invention provides a physical water treatment (PWT) method and apparatus to treat liquid coolants. Electrodes (22, 24) are provided in a coolant stream (21), and an alternating voltage is applied across the electrodes (22, 24) to produce an electric field through the coolant. The alternating voltage creates an oscillating electric field in the coolant that promotes the collision of dissolved mineral ions. The ions collide to form seed particles that precipitate out of solution. Bulk precipitation of seed particles decreases the availability of ions in solution which can crystallize on heat transfer surfaces. The seed particles adhere to additional ions that separate out of solution and form larger particles that may be removed from the coolant stream (21) using a variety of treatment measures. In addition to precipitating mineral ions, the electric field may be applied to destroy bacteria, algae and microorganisms that accumulate in the coolant stream (21).

  • Publication number: 20070190709
    Abstract: Provided is a multiple-gate metal oxide semiconductor (MOS) transistor and a method for manufacturing the same, in which a channel is implemented in a streamline shape, an expansion region is implemented in a gradually increased form, and source and drain regions is implemented in an elevated structure by using a difference of a thermal oxidation rate depending on a crystal orientation of silicon and a geographical shape of the single-crystal silicon pattern. As the channel is formed in a streamline shape, it is possible to prevent the degradation of reliability due to concentration of an electric field and current driving capability by the gate voltage is improved because the upper portion and both sides of the channel are surrounded by the gate electrodes. In addition, a current crowding effect is prevented due to the expansion region increased in size and source and drain series resistance is reduced by elevated source and drain structures, thereby increasing the current driving capability.
