Abstract: An acoustic resonator device includes a composite first electrode on a substrate, a piezoelectric layer on the composite electrode, and a second electrode on the piezoelectric layer. The first electrode includes a buried temperature compensating layer having a positive temperature coefficient. The piezoelectric layer has a negative temperature coefficient, and thus the positive temperature coefficient of the temperature compensating layer offsets at least a portion of the negative temperature coefficient of the piezoelectric layer.

Abstract: A method for fabricating a resonator, and in particular, a thin film bulk acoustic resonator (FBAR), and a resonator embodying the method are disclosed. An FBAR is fabricated on a substrate by reducing mass from a top electrode layer. For a substrate having multiple resonators, mass is reduced from only selected resonator to provide resonators having different resonance frequencies on the same substrate.

Abstract: A filter formed of acoustic resonators, where each resonator has its own cavity and a bottom electrode that spans the entirety of the cavity, so that the bottom electrode has an unsupported interior region surrounded by supported peripheral regions. In the preferred embodiment, the cavity is formed by etching a depression into the substrate, filling the depression with a sacrificial material, depositing the piezoelectric and electrode layers that define an FBAR or SBAR, and then removing the sacrificial material from the depression. Also in the preferred embodiment, the sacrificial material is removed via release holes that are limited to the periphery of the depression. Preferably, the bottom electrode is the only electrode that spans the cavity, thereby limiting the formation of parasitic FBARs or SBARs. In one embodiment, the bottom electrode includes a serpentine edge that leaves a portion of one side of the cavity free of overlap by the bottom electrode, so that a top electrode may overlap this portion. Thus, the top and bottom electrodes can overlap the same side without sandwiching the piezoelectric layer outside of the unsupported interior region.

Abstract translation: 由声谐振器形成的滤波器，其中每个谐振器具有其自身的空腔和跨越整个空腔的底部电极，使得底部电极具有被支撑的周边区域包围的无支撑的内部区域。 在优选实施例中，通过将凹陷蚀刻到基板中，用牺牲材料填充凹陷，沉积限定FBAR或SBAR的压电层和电极层，然后从凹陷中去除牺牲材料来形成空腔。 同样在优选实施例中，通过限制在凹陷周边的释放孔去除牺牲材料。 优选地，底部电极是跨越空腔的唯一电极，从而限制寄生FBAR或SBAR的形成。 在一个实施例中，底部电极包括使空腔的一侧的一部分离开由底部电极重叠的蛇形边缘，使得顶部电极可能与该部分重叠。 因此，顶部和底部电极可以重叠在同一侧，而不将压电层夹在未支撑的内部区域之外。

Abstract: A method for making metal/ceramic superconductor thick film structures including the steps of preparing a silver/superconductor ink, applying the ink to a substrate, evaporating the ink's binder, decomposing a silver compound in the residue to coat the superconductor grains, sintering the coated superconductor grains, and oxygenating the superconductor grains through the silver coating. The resultant inter-granular silver increases the critical current and mechanical strength of the superconductor.
