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.

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.

The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system. A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity.

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. .

. The BQ25792 is available in a 4mm x 4mm, 29-pin QFN package and is available now from TI and authorized resellers. Complete reels and custom reels are available on TI.com and through other channels, starting in 1,000 pieces. The BQ25790 is available in a 2.9mm x 3.3mm, 56-pin WCSP package and is available now from TI and its authorized resellers.

Quartz (quartz), as a common piezoelectric material, exhibits linear response under high voltage and high pressure, but there is no suitable method to make quartz into thin film deposits on Si substrates. A suitable BAW piezoelectric material needs high electromechanical coupling coefficient, low electromechanical loss, high thermal stability, and also conforms to IC process technology.

Physically, waves are mainly divided into two types, one is electromagnetic wave, which does not require any medium, but propagates through the periodic oscillation of the electric and magnetic fields generated by the initially charged particles, so in a vacuum can also spread. Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves.
