    摘要: A semiconductor device using an oxide semiconductor is provided with stable electric characteristics to improve the reliability. In a manufacturing process of a transistor including an oxide semiconductor film, an oxide semiconductor film containing a crystal having a c-axis which is substantially perpendicular to a top surface thereof (also called a first crystalline oxide semiconductor film) is formed; oxygen is added to the oxide semiconductor film to amorphize at least part of the oxide semiconductor film, so that an amorphous oxide semiconductor film containing an excess of oxygen is formed; an aluminum oxide film is formed over the amorphous oxide semiconductor film; and heat treatment is performed thereon to crystallize at least part of the amorphous oxide semiconductor film, so that an oxide semiconductor film containing a crystal having a c-axis which is substantially perpendicular to a top surface thereof (also called a second crystalline oxide semiconductor film) is formed.

    摘要: A semiconductor device which can operate at high speed and consumes a smaller amount of power is provided. In a semiconductor device including transistors each including an oxide semiconductor, the oxygen concentration of the oxide semiconductor film of the transistor having small current at negative gate voltage is different from that of the oxide semiconductor film of the transistor having high field-effect mobility and large on-state current. Typically, the oxygen concentration of the oxide semiconductor film of the transistor having high field-effect mobility and large on-state current is lower than that of the oxide semiconductor film of the transistor having small current at negative gate voltage.

    摘要: The present invention provides a method for manufacturing an SOI substrate, to improve planarity of a surface of a single crystal semiconductor layer after separation by favorably separating a single crystal semiconductor substrate even in the case where a non-mass-separation type ion irradiation method is used, and to improve planarity of a surface of a single crystal semiconductor layer after separation as well as to improve throughput. The method includes the steps of irradiating a single crystal semiconductor substrate with accelerated ions by an ion doping method while the single crystal semiconductor substrate is cooled to form an embrittled region in the single crystal semiconductor substrate; bonding the single crystal semiconductor substrate and a base substrate with an insulating layer interposed therebetween; and separating the single crystal semiconductor substrate along the embrittled region to form a single crystal semiconductor layer over the base substrate with the insulating layer interposed therebetween.
