We present a robust, chip-scale packaged FBAR oscillator that is compatible with high volume manufacturing. The oscillator's extremely small size (area < 1 mm2, thickness = 0.23 mm) combined with an SMT-compatible pad design enables integration of th

We present a fourth-design generation Free Running Oscillator and Voltage Controlled Oscillator using integrated bipolar circuitry in the lid wafer with a temperature-compensated FBAR resonator in the base wafer. The goal is to produce a high frequen

Analysis and sample preparation techniques for the bulge test have been improved to the point where the test can provide reliable and accurate measurements of the mechanical properties of thin films. Ag-Pd multilayer films of variable bilayer period

Recent advances in temperature-compensation for FBAR (Film Bulk Acoustic Resonators) have brought this technology forward as a serious contender in the oscillator marketplace. As with any mechanical resonator oscillator, a cost-effective hermetic pac

This paper demonstrates two variations of Temperature compensated (TempCo) FBAR resonators with high Kt2. One 1.5 GHz non-symmetric stack design TempCo FBAR resonator has a Kt2 of 4.28% and linear TCF of 0 ppm/°C. A second, quasi-symmetric stack des

Since its first application to thin films in the 1950's the bulge test has become a standard technique for measuring thin film mechanical properties. While the apparatus required for the test is simple, interpretation of the data is not. Failure to r

The elastic biaxial modulus of a polycrystalline material as a function of [111] fiber texture was determined by imposing an equibiaxial strain and calculating the resulting stress assuming a plane-stress condition. The situation of a such a texture

In this paper we address possible causes for inconsistencies in bulge test results and describe methods by which the bulge test technique can be made to produce accurate and reliable results. Experiments have been conducted on a variety of materials:
