  • Publication number: 20190206725
    Abstract: Multi-patterning methods are provided for use in fabricating an array of metal lines comprising metal lines with different widths. For example, patterning methods implement spacer-is-dielectric (SID)-based self-aligned double patterning (SADP) methods for fabricating an array of metal lines comprising elongated metal lines with different widths, wherein an “unblock” mask is utilized as part of the process flow to overlap mandrel assigned and non-mandrel assigned features in a given SADP pattern to define regions to unblock a metal fill (remove dielectric material between wires) in a dielectric layer between defined metal lines of an a SADP pattern thus enabling the formation of wide metal lines within any region of a pattern of elongated metal lines formed with a minimum feature width.

  • Patent number: 9973537
    Abstract: A method for updating security information is applied to a system including an information service provider and mobile devices. The information service provider includes a server and a database, in which the server provides security information to the mobile devices and each of the security information is related individually to a security code. The information service provider can transmit updated security information to the mobile devices in an active-push manner in communicative off-peak hours, and at the same time each of the mobile devices would be automatically waken up and connected with the service-provider so as to receive the updated security information. While the mobile device is to request additional information, the passive-pull transmission manner can then be applied by the mobile device to obtain the additional information from the information service provider. Thus, merits of both the active push transmission and the passive pull transmission can be obtained.

  • Publication number: 20170069025
    Abstract: An alerting method by using trend lines of security information is implemented in a client device of a security information processing system. The method allows a client device to choose and drag at least one trend line in a technical diagram of security information to form at least one alerting line so as to generate at least one alerting condition corresponding to the trend line and the dragging operations. When the client device receives a plurality of security information, the client device checks if any of the received security information matches any one of the alerting conditions by passing the alerting line twice. If “YES”, then the client device generates an alerting signal and displays that matched security information on the client device, such that the user can see the matched security information and take it as a reference for deciding whether or not to buy or sell the security.

  • Publication number: 20170032128
    Abstract: A processing method for fuzzy checking securities information, which is employed in a user device of a securities information processing system, allows a user to execute a securities suggesting setting function in order to configure at least one securities suggesting condition composed of at least one candlesticks checking condition. In addition, each candlesticks checking condition includes a fuzzy checking condition which can be defined by the user. When the user device receives a plurality of securities information, these securities information are checked to see if any of them fulfills all of the fuzzy checking conditions of candlesticks checking conditions contained in any of the securities suggesting conditions. If the result is positive, then the user device suggests and prompts the fulfilled securities information to the user so as to provide a reference to the user for determining when to buy or sell the securities in which the user is interested.

  • Publication number: 20160048918
    Abstract: An alerting method of a trend of security information is implemented in a client device of a security information processing system. The method allows a user of the client device to click and drag at least one trend line on a technical graph of security information to form at least one alerting line so as to generate at least one advising condition corresponding to the trend line and the user's click-and-drag operations. When the client device receives a plurality of security information, the client device checks if any of the received security information matches any one of the advising conditions. If “YES”, then the client device generates an alerting signal and displays that matched security information on the client device, such that the user can see the matched security information and take it as a reference for deciding whether or not to buy or sell the security.

  • Publication number: 20070201173
    Abstract: An apparatus for protecting an integrated circuit from electrostatic discharge (ESD) includes an RC trigger device configured between a pair of power rails, a first control path coupled to the RC trigger device, and a second control path coupled to the RC trigger device. A power clamp is configured between the power rails for discharging current from an ESD event, the power clamp having an input coupled to outputs of the first and second control paths, the power clamp independently controllable by the first and second control paths. The first and second control paths are further configured to prevent the power clamp from reactivating following an initial deactivation of the power clamp.

  • Publication number: 20050239145
    Abstract: The present invention comprises a method for rapid detection of at least a first carbohydrate in a carbohydrate-containing sample molecule comprising the steps of: (a) retaining the sample molecule on a region of one liquid permeable reaction membrane, (b) flowing a solution of first lectin, capable of binding the first carbohydrate, through the one reaction membrane to bind the first lectin to the retained first carbohydrate, the lectin being directly conjugated to a label prior to binding to the carbohydrate or being bound to a labeled separate molecule only after the first lectin has been bound to the carbohydrate, and (c) thereafter, detecting the label bound on the one reaction membrane, indicating the presence of the first carbohydrate.
