Optimisation de transducteurs ultrasonores hautes fréquences à base de ZnO pour applications MEMS, Optimization of high-frequency ZnO-based ultrasonic transducers for MEMS applications

Reda Aitayad

Ce manuscrit porte sur la fabrication et l’optimisation de transducteurs à ondes acoustiques de volume (BAW) à base de couches minces de ZnO. L’optimisation concerne d’abord le matériau piézoélectrique en couche mince : le dépôt du ZnO par pulvérisation cathodique RF est optimisé, et la condition…, This manuscript focuses on the fabrication and optimization of bulk acoustic wave (BAW) transducers based on ZnO thin films. The optimization first concerns the piezoelectric thin-film material: ZnO deposition by RF magnetron sputtering is optimized, and the 80% Ar / 20% O₂ condition makes it…
