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.

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.

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. Today, timing often requires a quartz crystal. "Everyone uses quartz crystals for clocks," Solis said.

So, does this mean that 150mm wafers are gradually withdrawing from the stage of history? The answer is no, there is still a huge market space for 150mm wafers. A large number of 150mm fabs in the industry were closed, and more and more 300mm fabs were launched and gradually achieved mass production.

. 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.

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

There are also different structures where sound waves propagate as transverse waves. In the above-mentioned BAW-SMR and FBAR?filter diagrams, sound waves propagate in the form of longitudinal waves, that is, the direction of particle vibration and the direction of wave propagation are parallel.

. The resonator used in the Ladder type (SAW is also mentioned later) includes series and parallel. A series resonator plus a parallel resonator is called a stage, and the entire ladder type filter can be composed of several stages.
