摘要： A single crystal semiconductor substrate is irradiated with ions that are generated by exciting a hydrogen gas and are accelerated with an ion doping apparatus, thereby forming a damaged region that contains a large amount of hydrogen. After the single crystal semiconductor substrate and a supporting substrate are bonded, the single crystal semiconductor substrate is heated to be separated along the damaged region. While a single crystal semiconductor layer separated from the single crystal semiconductor substrate is heated, this single crystal semiconductor layer is irradiated with a laser beam. The single crystal semiconductor layer undergoes re-single-crystallization by being melted through laser beam irradiation, thereby recovering its crystallinity and planarizing the surface of the single crystal semiconductor layer.

摘要： A semiconductor substrate is irradiated with accelerated hydrogen ions, thereby forming a damaged region including a large amount of hydrogen. After a single crystal semiconductor substrate and a supporting substrate are bonded to each other, the semiconductor substrate is heated, so that the single crystal semiconductor substrate is separated in the damaged region. A single crystal semiconductor layer which is separated from the single crystal semiconductor substrate is irradiated with a laser beam. The single crystal semiconductor layer is melted by laser beam irradiation, whereby the single crystal semiconductor layer is recrystallized to recover its crystallinity and to planarized a surface of the single crystal semiconductor layer. After the laser beam irradiation, the single crystal semiconductor layer is heated at a temperature at which the single crystal semiconductor layer is not melted, so that the lifetime of the single crystal semiconductor layer is improved.

摘要： To provide a high-performance semiconductor device using an SOI substrate in which a substrate having low heat resistance is used as a base substrate, to provide a high-performance semiconductor device without performing mechanical polishing, and to provide an electronic device using the semiconductor device, planarity of a semiconductor layer is improved and defects in the semiconductor layer are reduced by laser beam irradiation. Accordingly, a high-performance semiconductor device can be provided without performing mechanical polishing. In addition, a semiconductor device is manufactured using a region having the most excellent characteristics in a region irradiated with the laser beam. Specifically, instead of the semiconductor layer in a region which is irradiated with the edge portion of the laser beam, the semiconductor layer in a region which is irradiated with portions of the laser beam except the edge portion is used as a semiconductor element. Accordingly, performance of the semiconductor device can be greatly improved. Moreover, an excellent electronic device can be provided.

摘要： A semiconductor substrate including a single crystal semiconductor layer with a buffer layer interposed therebetween is manufactured. A semiconductor substrate is doped with hydrogen to form a damaged layer containing a large amount of hydrogen. After the single crystal semiconductor substrate and a supporting substrate are bonded, the semiconductor substrate is heated so that the single crystal semiconductor substrate is separated along a separation plane. The single crystal semiconductor layer is irradiated with a laser beam from the single crystal semiconductor layer side to melt a region in the depth direction from the surface of the laser-irradiated region of the single crystal semiconductor layer. Recrystallization progresses based on the plane orientation of the single crystal semiconductor layer which is solid without being melted; therefore, crystallinity of the single crystal semiconductor layer is recovered and the surface of the single crystal semiconductor layer is planarized.

摘要： To provide an SOI substrate with an SOI layer that can be put into practical use, even when a substrate with a low allowable temperature limit such as a glass substrate is used, and to provide a semiconductor substrate formed using such an SOI substrate. In order to bond a single-crystalline semiconductor substrate to a base substrate such as a glass substrate, a silicon oxide film formed by CVD with organic silane as a source material is used as a bonding layer, for example. Accordingly, an SOL substrate with a strong bond portion can be formed even when a substrate with an allowable temperature limit of less than or equal to 700° C. such as a glass substrate is used. A semiconductor layer separated from the single-crystalline semiconductor substrate is irradiated with a laser beam so that the surface of the semiconductor layer is planarized and the crystallinity thereof is recovered.
