  • Patent number: 6997040
    Abstract: A gas sensor includes a silicon substrate provided with a recess, an insulating layer, a first and a second conductive patterned layers and a detecting portion for sensing a gas which passes there through. In the gas sensor, the insulating layer is formed on a top portion of the silicon substrate which does not form the recess. The first and the second conductive patterned layers extend over the recess, thereby being apart from the silicon substrate physically. The detecting portion is formed on both portions of the first and the second conductive patterned layers.

  • Patent number: 6844108
    Abstract: To compliment the drawback of the conventional large-size reserve battery cell inapplicable to a small electronic system, disclosed is a super-slim reserve battery cell sized merely several millimeters in its entirety including micro-size battery elements sized about several ?m by using a micro-machining technology of processing mechanical structures in a super-slim size. The present invention realized electrolyte container and other battery elements by using materials such as silicon, nickel, copper, aluminum, etc. to form a membrane structure of relatively thinner thickness than the periphery in an electrolyte container contiguous with the battery cell that is broken only when activating the cell. Therefore, it is possible to activate the battery cell with less power while securing sufficient impact-resistant characteristics under normal circumstances.
