    • A method for manufacturing a bulk acoustic wave resonator, each resonator including: above a substrate, a piezoelectric resonator, and next to the piezoelectric resonator, a contact pad connected to an electrode of the piezoelectric resonator; and, between the piezoelectric resonator and the substrate, a Bragg mirror including at least one conductive layer extending between the pad and the substrate and at least one upper silicon oxide layer extending between the pad and the substrate, the method including the steps of: depositing the upper silicon oxide layer; and decreasing the thickness unevenness of the upper silicon oxide layer due to the deposition method, so that this layer has a same thickness to within better than 2%, and preferably to within better than 1%, at the level of each pad.
    • 一种制造体声波谐振器的方法,每个谐振器包括:在基板上方,压电谐振器上方,并且紧邻压电谐振器,连接到压电谐振器的电极的接触焊盘; 并且在所述压电谐振器和所述基板之间,布拉格反射镜包括在所述焊盘和所述衬底之间延伸的至少一个导电层和在所述焊盘和所述衬底之间延伸的至少一个上部氧化硅层,所述方法包括以下步骤: 上氧化硅层; 并且由于沉积方法而减小上部氧化硅层的厚度不均匀性,使得该层在每个焊盘的水平处具有相同的厚度,优于2%以内,优选在1%以内。
