Abstract: A method of manufacturing a semiconductor package includes the following steps. A backside redistribution structure is formed, wherein the backside redistribution structure comprises a first dielectric layer, and a redistribution metal layer over the first dielectric layer and comprising a dummy pattern. A semiconductor device is provided over the backside redistribution structure, wherein an active surface of the semiconductor device faces away from the backside redistribution structure, the semiconductor device is electrically insulated from the dummy pattern and overlapped with the dummy pattern from a top view of the semiconductor package. A front side redistribution structure is formed over the semiconductor device, wherein the front side redistribution structure is electrically connected to the semiconductor device. A patterning process is performed on the first dielectric layer to form a marking pattern opening exposing a part of the dummy pattern.

Abstract: A method and a system for evaluating/analyzing patent portfolio using patent priorities are provided for selecting a patent family to establish a data set based on members of the patent family and priorities claimed by the members, forming a relationship matrix based on the members and the priorities claimed by the members in the data set and at last, and analyzing a relationship between the members of the patent family and the priorities claimed by the members of the patent family through the relationship matrix to form an analysis result and then, performing patent evaluation patent portfolio according to the analysis result. Accordingly, a patentee having numerous patents may quickly know what patents have high importance, high value and high techniques and the patentee or his competitor is facilitated to perform patent evaluation, patent portfolio, patent application and patent maintenance.

Abstract: A refuse burning equipment with a heat energy utilizing system includes a first burning room and a second burning room connected with the first one with a burning gas passageway. The first burning room have two tubular fences made of a tube bent into many parallel tubes of horizontal or vertical direction for condensed water to flow through to cool it. Refuse is conveyed through a distributor and pushed down by a screw pusher to be piled in the tubular fences as a thin and high of refuse wall, which then is dried and lowered down gradually by a roller above a furnace grate and then ignited by fuel oil sprayed out of a nozzle. Time for the refuse drying before unload on the grate and chance of refuse to contact with combustion gas are augmented to lower the excess air ratio required in the burning and the temperature of the combustion gas is greatly increased and thus the thermal efficiency improved.
