    摘要: A secondary battery to be provided includes an electrode including silicon or a silicon compound, and the electrode includes, for example, a current collector formed using metal and a silicon film as an active material provided over the current collector. The hydrogen concentration in the silicon film of the electrode may be higher than or equal to 1.0×1018 cm−3 and lower than or equal to 1.0×1021 cm−3. Such a silicon film is formed over a current collector by a plasma CVD method or the like for example, and hydrogen is contained as little as possible in the silicon film, which is preferable. In order to contain hydrogen as little as possible in the silicon film, the silicon film may be formed over the current collector under a high temperature environment.

    摘要: An object of the present invention is to provide a method for manufacturing an SOI substrate provided with a semiconductor layer which can be used practically even where a substrate having a low upper temperature limit such as a glass substrate is used. The manufacturing method compromises the steps of preparing a semiconductor substrate provided with a bonding layer formed on a surface thereof and a separation layer formed at a predetermined depth from the surface thereof, bonding the bonding layer to the base substrate having a distortion point of 700° C. or lower so that the semiconductor substrate and the base substrate face each other, and separating a part of the semiconductor substrate at the separation layer by heat treatment in order to form a single-crystal semiconductor layer over the base substrate. In the manufacturing method, a substrate which shrinks isotropically at least by the heat treatment is used as the base substrate.

In an electrode for the power storage device, phosphorus-doped amorphous silicon is used for the active material layer over a current collector as a material that can be alloyed with lithium, and niobium oxide is deposited over the active material layer as a layer containing niobium. Accordingly, the capacity of the power storage device can be increased and the cycle characteristics and the charge-discharge efficiency can be improved.
