Abstract: A semiconductor structure is provided with a test region. In test region, the semiconductor structure includes a semiconductor substrate, a plurality of bit line contact structures arranged on semiconductor substrate and a plurality of wire groups. The semiconductor structure is provided with a plurality of separate active regions extending along a first direction. In first direction, each active region is electrically connected to two bit line contact structures. The plurality of wire groups are arranged along a second direction. Each wire group includes a plurality of wires extending along a third direction. In third direction, each of two bit line contact structures for each active region is connected to respective one of two bit line contact structures for active region adjacent to said each active region by a respective one of wires, so that two wire groups of the wire groups cooperate with each other to form a conductive path.

Abstract: An automatic uploading method, comprising the steps of: receiving a wake-up signal by a low-power-consumption wireless transmission module of a portable information capturing device; actuating a high-power-consumption wireless transmission module of the portable information capturing device according to the wake-up signal; creating a connection between the high-power-consumption wireless transmission module and a first relay station after the high-power-consumption wireless transmission module has been actuated; shutting down the low-power-consumption wireless transmission module after the connection has been created; and transmitting, via the connection, an upload data of the portable information capturing device to a second relay station, wherein the second relay station is connected to the first relay station.
