Abstract: An organic light-emitting device having a porous desiccant layer therein and a method for fabricating the same is provided. The porous desiccant layer is manufactured by spreading a liquid desiccant on a surface, forming air bubbles (by activating some vesicant or injecting gas into the liquid desiccant) and curing the liquid desiccant. The porous desiccant comprises solidified hardening glue having bubbles and lots of desiccant particles or powder distributed evenly therein. Some residual vesicant may remain inside the solidified hardening glue after activation. The bubbles inside the porous desiccant enhance the absorption rate and efficiency of the desiccant so that moisture and gaseous oxygen inside the OLED package can be absorbed rapidly.

Abstract: The present invention provides a design structure of an plated wire of a fiducial mark for a die-dicing package. In the present structure, a cutting line is positioned between each two adjacent ball grid array (BGA) chips. There is configured a solder mask opening at the edge connecting region of the cutting lines. A fiducial mark is positioned in the opening of each BGA chip, wherein the fiducial mark is close to the cutting line and positioned a plated wire therein to pull from the fiducial mark to out the opening and to connect to the plated wire of the cutting line. So as all the plated wires utilizing the coverage of the solder mask can be entirely cut without the pulling problem from the cutter. The present invention provides a new design structure of the plated wire to overcome the burr effect of prior die dicing so as to enhance the product efficiency and decrease the manufacturing cost.

Abstract: A method and apparatus for performing address translation in a computer system supporting virtual memory by searching a translation lookaside buffer (TLB) and, possibly, a translation table held in memory and implemented as a B-tree data structure. The TLB is initially searched for a translation for a specified input address. If exactly one valid entry of the TLB stores a translation for the specified input address then the output address corresponding to the specified input address is determined from the contents of that entry. Otherwise, the translation table is searched for a translation for the specified input address. If two or more valid entries of the TLB store a translation for the specified input address then these entries are invalidated.
