Title: Electronic device utilizing superconducting oxide thin film
Inventor: SATO HISASHI
IPC: H01L39/22
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To eliminate a buffer layer at the interface between a surface protection layer and a substrate by forming a superconducting oxide thin film of a very thin film, having a specific composition formed on a LaSrAlO4 substrate. SOLUTION: A superconducting oxide thin film 1 is formed of a very thin film, having the composition expressed by La2-x Srx CuO4+d (where x is 0 to 2 or less, d is -1 to +1) formed on the LaSrAlO4 substrate 3. The thin film has the thickness ranged, for example, from 0.66-5.3nm. When thickness 1 of the thin film is 0.66nm or less, it becomes smaller than molecule diameter of the oxide superconductor material, it is now impossible to form the oxide superconducting material having the composition expressed by the above formula. When thickness 1 exceeds 5.3nm, a degree of modulation of the electric characteristic of the oxide superconducting material thin film 1 is no longer the effective value for the practical use.  Thereby, it is possible to realize a field effect type 3-terminal element, having a larger modulation degree using a high temperature oxide superconducting material thin film 1 in which the buffer layer does not exist in the interface between the surface protection layer and substrate 3.

Title: Hybrid integrated circuit
Inventor: ANDO MASARU
IPC: G01R31/28
Filed: 1994-11-07
Abstract: PURPOSE: To provide a hybrid integrated circuit in which the connection between an external connecting terminal and wiring pattern can be confirmed easily with a simple circuit. CONSTITUTION: A test mode switching signal is given to a terminal 5 for switching to test. As a result, the output of a logic circuit 2 is fixed and, at the same time, a three-state buffer 4 is switched so that a test signal inputted to a test input terminal 6 can be outputted to an external terminal 8 for input. The connecting state of the terminal 8 is tested by giving the test signal to the terminal 6 and checking an output signal from the external terminal 8. On the other hand, since the input to an internal circuit 1 is fixed by means of the logic circuit 2, the output of the internal circuit 1 is also fixed. Therefore, signals from a logic circuit 3 change in accordance with the test signal given to a terminal for test input. The connecting state of an external terminal 9 for output is tested by detecting the signals from the circuit 3.
