Title: Manufacture of oxide superconductive compact
Inventor: SHIGA SHOJI
IPC: H01B13/00
Filed: 1987-11-27
Abstract: PURPOSE:To improve the productivity in manufacture of a lengthy material by forming an oxide superconductor component in a film form on a running continuous filament substrate by means of a PVD method to increase oxygen in the film body. CONSTITUTION:A superconductor component is formed in a film form on a substrate by using superconductor materials and precusors to provide a superconductor material, for example, sintered bodies of YBa2.5Cu4.6OX, alloys such as YBa2.2Cu3.3, or compounds such as Y2O3, BaCO3, and CuO, by means of a PVD method such as spattering in vacuum or low O2 pressure atmosphere. Inconveniences such as amorphous tendency of crystals and reduction in film forming speed are avoided by the subsequent O2 increasing treatment. As both steps of film forming 1 and O2 increasing 2 can be conducted under a low pressure condition of the same degree, they are advantageously disposed in the same treating chamber 9 without shielding each other to control the atmosphere locally in each step. Hence, a lengthy oxide superconductive compact excellent in superconducting properties such as critical current density can be efficiently mass-produced at a high speed.

Abstract: PROBLEM TO BE SOLVED: To prevent the contamination which might be caused by the racrifice oxidation method by etching the surface of a semiconductor wafer under test to remove its working strain layer before forming a measuring element. SOLUTION: Before forming a measuring element, a finish-polished semiconductor wafer under test is etched with an SC-1(NH4 OH/H2 O2 /H2 O) liq. to remove a surface working strain layer of the wafer, and GOI (oxide film dielectric strength characteristic) of each semiconductor wafer is measured to compute the non-defective ratio such that the finish-polished surface of the semiconductor wafer is etched to a depth of 10nm or more to measure GOT (oxide film dielectric strength characteristic), thereby preparing a sample to evaluate the crystal quality. Thus it is possible to prevent the contamination which might be caused by the sacrific oxidation method and improve the semiconductor wafer quality.

Title: Wavelength-variable light-emitting element
Inventor: MIYAZAKI KOICHI
IPC: H01L33/30
Filed: 1988-11-25
Abstract: PURPOSE:To make this element small-sized by a method wherein a plurality of active layers which emit light at different wavelengths are formed inside an identical element and a plurality of gates are formed inside a common substrate supporting the active layers. CONSTITUTION:A P-type gate 3 filled inside an N-type substrate 1 is controlled by an external control system 9. A positive voltage is applied to an electrode 1; a negative voltage is applied to an electrode 1'; the negative voltage is applied to a P-type gate 3' (part of A); then a negative electric field is generated in its circumference. Accordingly, an electron supplied from the electrode 1' is repelled and flows toward the P-type gate 3; when it is passed through the P-type gate 3, it is coupled with a hole supplied from the electrode 1 at an active layer 6 and emits light at its intrinsic light-emitting wavelength. When the negative voltage is applied to the P-type gate 3 (part of B), the electron flows toward the P-type gate 3', is coupled with the hole at an active layer 6' and emits light at its intrinsic light-emitting wavelength. In addition, when a voltage to the P-type gates 3, 3' is zero, the electron is passed around the P-type gates 3, 3' and is coupled with the hole; a mixed color can be obtained. Thereby, it is possible to control a light-emitting wavelength by a gate which can be controlled externally.
