摘要:
In a method of treating a semiconductor element which at least includes a semiconductor, a threshold voltage of the semiconductor element is changed by irradiating the semiconductor with light with a wavelength longer than an absorption edge wavelength of the semiconductor. The areal density of in-gap states in the semiconductor is 1013 cm−2eV−1 or less. The band gap may be 2 eV or greater. The semiconductor may include at least one selected from the group consisting of In, Ga, Zn and Sn. The semiconductor may be one selected from the group consisting of amorphous In—Ga—Zn—O (IGZO), amorphous In—Zn—O (IZO) and amorphous Zn—Sn—O (ZTO). The light irradiation may induce the threshold voltage shift in the semiconductor element, the shift being of the opposite sign to the threshold voltage shift caused by manufacturing process history, time-dependent change, electrical stress or thermal stress.

Disclosed is an information detecting device capable of reducing fluctuation in detection accuracy. A recording sheet P transported through a transport path comes into contact with a displacing member, and, in this state, a motor is driven to rotate a cam, and the resilient force of a coil spring causes a pressurizing member to collide with the recording sheet P. The impact force at that time is detected by a detection sensor, and transmitted to a sheet material information obtaining means. Then, on the basis of the detection result, it is possible to detect the type, density, thickness, surface irregularities, etc. of the recording sheet P. At this time, the recording sheet P is in contact with the displacing member, whereby it is possible to reduce fluctuation in detection accuracy due to positional deviation of the recording sheet P.
