Patent ID: 7791077

Claim:
An electronic device including an insulation film formed on an insulating substrate, a non-crystallized semiconductor thin film formed on the insulation film, a crystallized region in which a predetermined transistor formation region of the non-crystallized semiconductor thin film is crystallized in a lateral direction, and a plurality of semiconductor devices which are formed in the non-crystallized semiconductor thin film or the crystallized region on the insulation film, the plurality of semiconductor devices including: a MOS thin-film transistor; and at least either one of a lateral bipolar thin-film transistor and a MOS-bipolar hybrid thin-film transistor, wherein a base region or a channel region of the lateral bipolar thin-film transistor and the MOS-bipolar hybrid thin-film transistor is provided in a single crystallized region, and the channel region of the MOS thin-film transistor is provided in the non-crystallized semiconductor thin film or the crystallized region, and directions of movement of carriers in the MOS thin-film transistor, the lateral bipolar thin-film transistor and the MOS-bipolar hybrid thin-film transistor formed in the crystallized region are parallel to the direction of the crystallization.
