Abstract: Aspects of the invention relate to techniques for determining edge fragment correlation information. With various implementations of the invention, image intensity slope information for edge fragments in a layout design is determined. The image intensity slope information comprises information describing how image intensity for each of the edge fragments changes with its position. Image amplitude sensitivity information for the edge fragments is also determined. The image amplitude sensitivity information comprises information describing how image amplitude for each of the edge fragments changes with positions of neighboring edge fragments. Based on the image intensity slope information and the image amplitude sensitivity information, edge fragment correlation information for the edge fragments is determined. Using the edge fragment correlation information, the layout design may be processed by using, for example, OPC techniques.

Abstract: One embodiment of the present invention provides a process for fabricating an electrode for a capacitor using carbon nanotubes (CNTs), wherein the electrode comprises a metal substrate and a layer of active material (CNTs) coated onto the metal substrate. Specifically, the process starts by dispersing CNTs in a solvent to form a suspension. Next, the CNTs are charged in the suspension. The metal substrate is then immersed in the suspension. Next, the CNTs are deposited onto the metal substrate using electrophoretic deposition (EPD) to form the layer of active material on the metal substrate. In particular, the layer of active material is formed on the metal substrate without using a binder, which effectively reduces contact resistance between the active material and the metal substrate.

Abstract: Disclosed is a method for preventing IP address cheating in dynamic address allocation. Firstly, check the source MAC address and the source IP address involved in an ARP packet sent from a subscriber terminal, i.e., detect whether there is a matching item in the legal subscriber address table; if so, process it normally, otherwise discard the ARP packet. In this way, an illegal subscriber cannot access to network through IP address cheating, but a legal subscriber can operate normally and continuously. For a subscriber terminal with a static IP address, a static item table is set in the legal subscriber address by manual configuration. When a new subscriber terminal asks for being allocated an IP address, check whether the IP address to be allocated has been set as a static item; if so, inform the subscriber terminal of applying for another IP address.
