Texas Instruments currently has 15 wafer fabs in 9 countries, of course, these plants include outdated capacity that is about to close, as well as new 300mm capacity. In April 2019, Diodes completed the acquisition of Texas Instruments' 150mm/200mm wafer fab (GFAB) in Greenock, Scotland, UK, as part of TI's strategy to gradually abandon outdated capacity.

Accurate rhythm is achieved through crystal oscillation. But when these expensive crystals wear out, they can vibrate or jump, affecting the accuracy of timekeeping.

This enables TI to introduce the industry's first crystalless wireless MCU for the embedded market, the SimpleLink CC2652RB, with the clock contained in the same chip. Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. At just 100 microns in size, these tiny timers are smaller than the diameter of a human hair, but they operate at much higher frequencies than quartz crystals, enabling the integration of high-precision and ultra-low jitter clocks directly into packages that contain other circuitry, TI say.

"The new BAW resonator technology is important because TI is integrating it into its silicon products, reducing design time, solution size and component cost," said Philip Solis, research director for connectivity and smartphone semiconductors at IDC.

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 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.

For SAW, also called Rayleighsurface wave, there are both longitudinal waves and transverse waves. . The particles in the solid vibrate in an elliptical trajectory, and the long axis of the ellipse is perpendicular to the surface of the solid.

However, the thin film structure needs to be strong enough to be unaffected by subsequent processes. 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.
