Texas Instruments (TI) said it will close its last two 150mm (6-inch) wafer fabs in the next few years while building its next 300mm (12-inch) fab at its Richardson, Texas, fab. "This will be a multi-year program that is expected to be completed no later than 2023 to 2025," Dave Pahl, head of investor relations at Texas Instruments, said on the conference call.

Among them, 42 150mm fabs and 24 200mm fabs were closed, while the number of closed 300mm fabs accounted for only 10% of the total. The details are shown in the figure below. According to IC Insights statistics, in the past 10 years (2009-2018), all 11-ball semiconductor manufacturers closed or rebuilt a total of 97 fabs. .

When asked why nobody in the industry has built something like a BAW resonator, Upton said, "It's very difficult to develop. But it's not easy to convert electrical energy into mechanical acoustics while keeping the signal stable and robust within a clean clock." TI has been involved in MEMS research for many years.

. 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.

There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter. Only the ladder type and lattice type are briefly introduced here. The BAW filter can connect multiple resonators according to a certain topology.

”. Ray Upton, vice president of TI’s Interconnect Microcontroller Group, said: “The ability to make accurate, informed decisions through the use and analysis of large amounts of data is a very important innovation capability. Wireless networks are at the heart of this data migration, and the ability to connect the last mile through connected devices is a critical part of the data loop.
