In April 2019, Texas Instruments released the construction plan for this 300mm fab, with an estimated investment of $3.1 billion. However, in view of the sluggish semiconductor market in 2019 and the unsatisfactory revenue situation, TI's plan to invest in the construction of a 300mm wafer fab in Richardson is not as smooth as originally expected, and it may be delayed for two years to complete.

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.

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.

”. 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.

The Membrane type is similar to the basic model of the BAW resonator, with air on both sides. Since the acoustic impedance of the air is much lower than that of the piezoelectric layer, most of the acoustic waves will be reflected back.
