    摘要: It is an object of the present invention to provide a method for manufacturing an SOI substrate having an SOI layer that can be used in practical applications with high yield even when a flexible substrate such as a glass substrate or a plastic substrate is used. Further, it is another object of the present invention to provide a method for manufacturing a thin semiconductor device using such an SOI substrate with high yield. When a single-crystal semiconductor substrate is bonded to a flexible substrate having an insulating surface and the single-crystal semiconductor substrate is separated to manufacture an SOI substrate, one or both of bonding surfaces are activated, and then the flexible substrate having an insulating surface and the single-crystal semiconductor substrate are attached to each other.

    摘要: A thin film transistor includes, as a buffer layer, a semiconductor layer which contains nitrogen and includes crystal regions in an amorphous structure between a gate insulating layer and source and drain regions, at least on the source and drain regions side. As compared to a thin film transistor in which an amorphous semiconductor is included in a channel formation region, on-current of a thin film transistor can be increased. In addition, as compared to a thin film transistor in which a microcrystalline semiconductor is included in a channel formation region, off-current of a thin film transistor can be reduced.

    摘要: In a manufacturing process of a semiconductor device, a manufacturing technique for reducing the number of lithography processes that use a photoresist and simplifying the process is provided, which improves throughput. An etching mask for forming a pattern of a layer to be processed such as a conductive layer or a semiconductor layer is manufactured without using a lithography technique that uses a photoresist. The etching mask is formed of a light absorption layer including a material which absorbs a laser beam. The mask is formed by irradiating the light absorption layer with a laser beam through a photomask and utilizing laser ablation by energy of the laser beam absorbed by the light absorption layer.
