Abstract: A temperature sensor that includes an organic-inorganic composite negative temperature coefficient thermistor and a transistor. The organic-inorganic composite negative temperature coefficient thermistor includes a thermistor layer which includes spinel-type semiconductor ceramic composition powder containing Mn, Ni and Fe and an organic polymer component, and a pair of electrode layers. The semiconductor ceramic composition powder has a molar ratio of Mn to Ni of 85/15≥Mn/Ni≥65/35 and a Fe content of 30 parts by mole or less when a total molar amount of Mn and Ni is regarded as 100 parts by mole, and has a peak with a local maximum value of around 29° to 31° in its X-ray diffraction pattern, a half width of which peak is 0.15 or more. The transistor is electrically connected with either one of the pair of electrode layers.

Abstract: An organic thin film transistor includes an insulating substrate (1), gate electrodes (2, 4), a gate insulating film (3), an organic semiconductor film (5), and a source electrode (6) and a drain electrode (7). The gate electrodes include a main gate electrode (2) that is disposed in a region opposed to a channel region between the source electrode and the drain electrode in the organic semiconductor film, and a pair of auxiliary gate electrodes (4) that are disposed in respective regions opposed to the source electrode and the drain electrode on the two sides of the main gate electrode. The main gate electrode and the auxiliary gate electrodes are electrically separated from each other. The contact resistance between the source and drain electrodes and the organic semiconductor film is controlled so as to be at a low level even when the organic thin film transistor is driven in a low voltage region, and the operation frequency can be sufficiently enhanced due to the channel length being shortened.
