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.

From a regional perspective, Japan closed the largest number of fabs. In addition, Renesas has adjusted its factory in Otsu, Shiga Prefecture, Japan, to manufacture optoelectronic devices. Take Renesas as an example. The company's two recently closed fabs are both 150mm, including a fab in Kochi Prefecture, Japan, which produces analog, logic devices and some obsolete micro components. It is reported that Renesas expects to close two more 150mm fabs in 2020 or 2021.

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

In the semiconductor industry, digital IC technology is very difficult and pursues the ultimate efficiency. Therefore, the often talked about 7nm, 5nm, and 3nm refers to the process used in the digital IC manufacturing process, which is mainly controlled by a few multinational companies, and the localization rate is extremely high. Low, so it has become the most concerned area of the market. .

·Selectable mode can improve performance and reduce overall cost: The selectable mode and stop function of TPS62840 can improve noise performance and reduce signal distortion. These advantages can help reduce solution cost because designers do not need to use more expensive precision signal chain components, sensors or radio solutions to perform the same function to achieve system requirements. .

The function of the analog chip is to connect the real world and the digital world. Most of the information in the world we live in is composed of continuous variables, such as sound waves, light intensity, current, temperature, etc. These variables must be processed by analog chips to become discrete variables that can be calculated by digital chips, that is, 0- 1 variable. .

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

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. 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. .

. Design engineers can use this MCU to achieve simpler and smaller designs while improving performance and reducing cost. TI's new product announcement includes an industry-first crystalless wireless microprocessor (MCU) that integrates a TI BAW resonator in a package. Time-to-market is accelerated as designers eliminate the need to screen, calibrate and assemble external quartz crystals.

Wireless networking is 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. "By leveraging and analyzing large numbers of Making accurate, informed decisions with data is a very important innovation capability.
