摘要： An object is to improve characteristics of a power storage device and achieve a long lifetime. In the case where a lithium nitride is used for a negative electrode active material of a power storage device, a plurality of lithium nitride layers with different lithium concentrations are stacked. For example, in the case where a first lithium nitride layer and a second lithium nitride layer are stacked over a current collector, lithium is contained in the first lithium nitride layer at a lower concentration than lithium contained in the second lithium nitride layer. In this case, a concentration of a transition metal of the first lithium nitride layer is higher than a concentration of the transition metal of the second lithium nitride layer. Note that another alkali metal may be used instead of lithium.

摘要： To prevent, in the case of irradiating a single crystal semiconductor layer with a laser beam, an impurity element from being taken into the single crystal semiconductor layer at the time of laser irradiation. In a manufacturing method of an SOI substrate, a single crystal semiconductor substrate and a base substrate are prepared; an embrittlement region is formed in a region at a predetermined depth from a surface of the single crystal semiconductor substrate by irradiating the single crystal semiconductor substrate with accelerated ions; the single crystal semiconductor substrate and a base substrate are bonded to each other with an insulating layer interposed therebetween; a single crystal semiconductor layer is formed over the base substrate with the insulating layer interposed therebetween by heating the single crystal semiconductor substrate to cause separation using the embrittlement region as a boundary; an oxide film formed on the single crystal semiconductor layer is removed; and at least a surface of the single crystal semiconductor layer is melted by irradiating the surface of the single crystal semiconductor layer with a laser beam after the removal of the oxide film. The number of times the single crystal semiconductor layer is melted by the irradiation with the laser beam is one.

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.
