Atrial fibrillation (AF) is the most common cardiac arrhythmia, and is responsible for the highest number of rhythm-related disorders and cardioembolic strokes worldwide. Intracardiac signal analysis during the onset of paroxysmal AF led to the discovery of pulmonary vein as a triggering source of AF, which has led to the development of pulmonary vein ablation — an established curative therapy for...
Minimization of circuit patterning on wafers is required for higher integrations of circuit elements in semiconductor devices and, therefore, extremely high preciseness and quality are strictly required for patterning of microstructures on photo masks. Particle deposition on the photo mask, such as oil dusts which are generated from mechanical bearings of the spin processors, is one of main causes...
