  • Publication number: 20120241914
    Abstract: A method of reducing contamination of contact pads in a metallization system of a semiconductor device. Fluorine contamination of contact pads in a semiconductor device can be reduced by appropriately covering the sidewall portions of a metallization system in the scribe lane in order to significantly reduce or suppress the out diffusion of fluorine species, which may react with the exposed surface areas of the contact pads. The quality of the bond contacts is enhanced, possibly without requiring any modifications in terms of design rules and electrical specifications.

  • Patent number: 7856616
    Abstract: An action-based in-process software defect prediction (ABDP) applies classifying records of a performed action to predict whether subsequent actions cause defects in a project. A performed action is previously defined herein as an operation performed based on tasks in Work Breakdown Structure (WBS) of the project. Rather than focusing on the reported defects, ABDP discovers the patterns of the performed action that may cause defects composing a historic data set, and uses analytical results to predict whether the subsequent actions are likely to generate defects composing another historic data set. Once actions with high probability of causing the defects are identified, stakeholders review these actions carefully and take appropriate corrective actions to create a fresh performed action. The fresh performed action is continually appended to the historic data sets of amending the defects to construct a new prediction model for further subsequent actions.

  • Patent number: 7848786
    Abstract: A portable electronic device has various functions such as mobile communication, multimedia entertainment, and data processing. The device includes a main body installed with two keyboards and two slide rails, and two sub-bodies respectively equipped with a display. The sub-bodies are pivoted to each other and rotate through a shaft, and slide along slide rails through connecting members on the main body respectively. Therefore, the sub-bodies can be lifted relative to the main body through the shaft and the connecting members, so as to be optionally drawn close to the main body with the two displays facing the same direction, or to stand on the main body with the two displays facing opposite directions. Therefore, two different operating modes are achieved.
