Title: Method for growth of pluralistically mixed crystal semiconductor
Inventor: ONABE KENTAROU
IPC: H01L21/208
Filed: 1981-02-27
Abstract: PURPOSE:To cause pluralistically mixed crystal semiconductor to grow under optimum conditions by using a solution of such composition as chemical affinity of dissolution reaction to a basic mixed crystal layer which has already grown in zero or less. CONSTITUTION:The basic idea is that degree of supersaturation of solutions required for prevention against danger of dissolution can be found by plotting a curve representing that chemical affinity of dissolution reaction becomes zero on a graph of equilibration between liquid and solid phases. For instance, the areas between a liquidus line indicating that equilibrium temperature TL=640 deg.C and a curve representing A=0 represent states where precipitation and dissolution reactions can concur. In other words, it corresponds to thermodynamic instability of interface between solid and liquid phases during crystal growth, i.e. such composition of a solution as danger of dissolution of the basic mixed crystal layer can take place. Therefore, for the purpose of preventing such danger, composition of the solution should at least fall in the area above the curve indicating A=0, and then a degree of supersaturation of a solution that is required for the basic mixed crystal layer not to be dissolved is to be acquired from equilibrium temperature and temperature difference corresponding to the composition of the solution.

Title: Solar battery cell
Inventor: SATO KATSUMI
IPC: H01L31/0693
Filed: 1988-02-10
Abstract: PURPOSE:To prevent the inverse direction breakdown of a solar battery cell, by positively making a current flow in the inverse direction, when an inverse voltage is applied to the solar battery cell, by making a first semiconductor region and a second semiconductor region short-circuited, and making a third semiconductor region and a fourth semiconductor short circuited, too. CONSTITUTION:When the photo detecting surface of a solar battery cell is irradiated with light, photoelectromotive force generates between a P-type GaAs layer 104 and an N-type GaAs layer 102, and operates as a battery in which a cathode 301 is negative and an anode 302 or an anode 303 is positive. A P-type GaAs region 101 and an N-type GaAs region 102 are shorted, and does not contribute to photovoltaic power generation. In solar battery cell modules connected in series via external connection electrodes 301, 302 or external connection electrodes 301, 303, an inverse voltage is applied, when a part of the solar battery cells is darken. At this time, the P-N junction formed by the P-type GaAs region 101 and the N-type GaAs region 103 is biased in forward direction, and a current flows from the cathode 301 to the anode 302 or 303. Therefore, inverse voltage is not applied to the P-N junction having original function of electric power generation as a solar battery cell.

IPC: G11C29/00
Filed: 1985-02-19
Abstract: PURPOSE:To obtain a counter measures by attaining compulsorily a mode for lowering power consumption and detecting surely an abnormal temperature through an initial device examination to be carried out prior to shipping and the like, when a chip detecting temperature has exceeded a specified value. CONSTITUTION:When an IC chip 10 exceeds a specified temperature, an output of a chip temperature detector 2 is reversed to L and an output CS of a NAND gate 11 comes out L through an inverter 12, even though a chip selecting signal anti CS is in the selective state at L. As a result, a constant current source of peripheral circuit 4-6 is cut off and is compulsorily moved to a mode of lowering a power consumption. And with the suppression of chip's heating, an output of semi-conductor storage device is stopped and then a temperature rising is assuredly detected. Thus even the initial device examination to be performed prior to the shipping assures the detection of an abnormal temperature of chips and makes it possible to take the specified measures.
