The company currently has two 300mm fabs named RFAB and DMO56. TI outsources much of its logic and embedded IC production to foundries, but mostly produces analog chips in its own factories.

Of the roughly $1.5 billion in annual production at the two 150mm fabs, a significant portion will be moved to 300mm fabs, increasing productivity and economics, Pahl said.

"Quartz crystals require additional components to extend their accuracy -- over time -- as their performance changes beyond controllable temperature changes," he added. In addition, Solis said, "using a BAW resonator is more efficient than using a quartz crystal. precise.

In short, advances in BAW technology have brought "higher performance, simpler design, lower cost and smaller size" to wired and wireless networks, Wong explained.

. In order to keep the acoustic wave in the piezoelectric film to oscillate, there must be sufficient isolation between the oscillating structure and the external environment to obtain a small loss and a large Q value. On the other side of the oscillating structure, the acoustic impedance of the piezoelectric material is not much different from that of other substrates (such as Si), so the piezoelectric layer cannot be deposited directly on the Si substrate. The propagation speed of sound waves in solids is ~5000m/s, which means that the acoustic impedance of solids is about 105 times that of air, so 99.995% of the sound wave energy will be reflected back at the boundary between the solid and the air, which is the same as the original wave (incident wave). together to form a standing wave.

Compared with BAW-SMR, a smaller part of the membrane type is in contact with the underlying substrate, which is not easy to dissipate heat. However, the thin film structure needs to be strong enough to be unaffected by subsequent processes.

A suitable BAW piezoelectric material needs high electromechanical coupling coefficient, low electromechanical loss, high thermal stability, and also conforms to IC process technology. Quartz (quartz), as a common piezoelectric material, exhibits linear response under high voltage and high pressure, but there is no suitable method to make quartz into thin film deposits on Si substrates.
