    摘要: Forming an insulating film on a surface of the single crystal semiconductor substrate, forming a fragile region in the single crystal semiconductor substrate by irradiating the single crystal semiconductor substrate with an ion beam through the insulating film, forming a bonding layer over the insulating film, bonding a supporting substrate to the single crystal semiconductor substrate by interposing the bonding layer between the supporting substrate and the single crystal semiconductor substrate, dividing the single crystal semiconductor substrate at the fragile region to separate the single crystal semiconductor substrate into a single crystal semiconductor layer attached to the supporting substrate, performing first dry etching treatment on a part of the fragile region remaining on the single crystal semiconductor layer, performing second dry etching treatment on a surface of the single crystal semiconductor layer subjected to the first etching treatment, and irradiating the single crystal semiconductor layer with laser light.

    摘要: An object is to manufacture a semiconductor device including an oxide semiconductor at low cost with high productivity in such a manner that a photolithography process is simplified by reducing the number of light-exposure masks. In a method for manufacturing a semiconductor device including a channel-etched inverted-staggered thin film transistor, an oxide semiconductor film and a conductive film are etched using a mask layer formed with the use of a multi-tone mask which is a light-exposure mask through which light is transmitted so as to have a plurality of intensities. In etching steps, a first etching step is performed by dry etching in which an etching gas is used, and a second etching step is performed by wet etching in which an etchant is used.
