Abstract:
Provided is a semiconductor device including magnetic tunnel junctions, which are spaced apart from each other on a substrate, and each of which includes a free magnetic pattern, a first pinned magnetic pattern, and a tunnel barrier pattern therebetween. The semiconductor device further includes a separation structure interposed between the magnetic tunnel junctions. The separation structure includes a second pinned magnetic pattern and a first insulating pattern stacked to each other.
Abstract:
A UV fluid sterilizer which makes it possible to effectively sterilize a fluid which has a low UV transmissivity and an advanced oxidation device with high oxidation efficiency using a turbulent flow. To this end, the UV sterilizer or advanced oxidation device has a spring coil or wrinkled pipe in a spiral shape to bring forth a turbulent or spiral flow in the fluid.
