摘要:
A semiconductor device production system using a laser crystallization method is provided which can avoid forming grain boundaries in a channel formation region of a TFT, thereby preventing grain boundaries from lowering the mobility of the TFT greatly, from lowering ON current, and from increasing OFF current. Rectangular or stripe pattern depression and projection portions are formed on an insulating film. A semiconductor film is formed on the insulating film. The semiconductor film is irradiated with continuous wave laser light by running the laser light along the stripe pattern depression and projection portions of the insulating film or along the major or minor axis direction of the rectangle. Although continuous wave laser light is most preferred among laser light, it is also possible to use pulse oscillation laser light in irradiating the semiconductor film.

A release layer formed over a substrate; at least one of thin film integrated circuits is formed over the release layer; a film is formed over each of the at least one of thin film integrated circuits; and the release layer is removed by using an etchant; thus, the at least one of thin film integrated circuits is peeled from the substrate. A semiconductor device is formed by sealing the peeled thin film integrated circuit by lamination or the like.

A data processing device which includes a flexible position input portion for sensing proximity or a touch of an object such as a user's palm and finger. In the case where a first region of the flexible position input portion is held by a user for a certain period, supply of image signals to the first region is selectively stopped.

Provided is an image sensor having a pixel includes a photoelectric conversion element; a capacitor which is connected between the photoelectric conversion element; a reset circuit which resets a potential of a node between the photoelectric conversion element and the capacitor; an amplifier circuit which outputs a signal corresponding to the potential of the node; and a switch which controls electrical conduction between the amplifier circuit and a vertical signal line. When the node is brought into an electrically floating state, the potential of the optical signal is stored in the node in a state of being inverted. When an optical signal is detected while the potential is stored in the node, the potential of the node increases in accordance with an output potential of the photoelectric conversion element, and thus the potential of the node corresponds to a difference in potential between the optical signals in different light-receiving periods.

A photoelectric conversion element includes a first electrode, a second electrode, a first layer, and a second layer. The first layer is provided between the first electrode and the second electrode. The second layer is provided between the first layer and the second electrode. The first layer contains selenium. The second layer contains In, Ga, Zn, and O. The second layer may contain an In—Ga—Zn oxide. The selenium may be crystalline selenium. The first layer functions as a photoelectric conversion layer. The second layer functions as a hole injection blocking layer. The In—Ga—Zn oxide may have a c-axis aligned crystal.
