Title: Solar battery
Inventor: MIZUSHIMA YOSHIHIKO
IPC: H01L31/04
Filed: 1978-02-07
Abstract: PURPOSE: To increase the efficiency of the output current by increasing the content ratio of the tellurium gradually from the side of the 2nd conducting layer toward the 1st conducting layer.  
     CONSTITUTION: The sunlight is introduced within photoelectric conversion layer 2 from the side of conducting layer 3, and the output corresponding to the incident sunlight is led outside via conducting layer 1 and 3. In this case, the tellurium content ratio of layer 2 is increased gradually from the side of layer 3 toward layer  3, and thus the energy inhibition band of layer 2 is larger at the side of layer 3 than the side of layer 1. On the other hand, layer 2 as it is the P-type semiconductor varies its conduction band position at each position in the thickness direction gradually from layer 3 toward layer 1. And the electric field is formed within layer 2 to accelerate the minor carrier produced within layer 2 based on the incidence of the sunlight from layer 3 side toward the layer 1 side. As a result, the optical carriers produced within layer 2 can be collected to layer 3 in a highly efficient way since the rectifying contact is given between layer 3 and layer 2.

Title: Ferroelectric gate memory, formation of ferroelectric thin film used therefor, and precursor solution used for the formation
Inventor: MITA MITSURO
IPC: H01L21/8246
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To enable application of such a voltage that spontaneous polarization formed in a ferroelectric thin film is saturated, by using a yttrium-manganese oxide having a relatively small relative dielectric constant as a ferroelectric thin film material in a ferroelectric gate memory. SOLUTION: A YMnO3 film 18 as a ferroelectric thin film is formed on the upper surface of an Si substrate 10 via an SiO2 film 14 as an insulating film, and a Pt electrode 20 as an upper electrode is stacked thereon. Thus, since the relative dielectric constant of the YMnO3 ferroelectric thin film is smaller than that of a conventional film, a voltage to be applied may be increased. Spontaneous polarization formed in the YMnO3 ferroelectric thin film is more likely to be saturated and residual dielectric polarization is increased. Therefore, the operating voltage of an MFMIS-FET using the YMnO3 ferroelectric thin film may be lowered. Also, the ratio of the voltage to be applied to a gate oxide film may be reduced so that dielectric breakdown of the gate oxide film is prevented.
