ABA3100_AD1888JCP Introduction

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.

But in fact, the global semiconductor market has an annual scale of US$470 billion, including four categories of digital chips (US$330 billion), analog chips (US$58.8 billion), sensors and discrete devices. When everyone pays attention to the domestic substitution strategy of semiconductors after dinner, they often equate semiconductors with digital integrated circuits represented by CPUs.

·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 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.

In the semiconductor industry, digital IC technology is difficult and pursues excellent efficiency. Therefore, the often-discussed 7nm, 5nm, and 3nm refer to the process used in digital IC manufacturing, which is mainly controlled by a few multinational companies. It is extremely low, so it has become an area that the market pays more attention to. .

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. Today, timing often requires a quartz crystal. "Everyone uses quartz crystals for clocks," Solis said.

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. .

"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." said Ray Upton, vice president of TI's Interconnect Microcontrollers Group: Large amounts of data to make accurate and informed decisions is a very important innovation capability.

As a common piezoelectric material, quartz exhibits a linear response under high voltage and high pressure, but there is no suitable method to make quartz into a thin film deposit on a Si substrate. Appropriate BAW piezoelectric materials require high electromechanical coupling coefficient, low electromechanical loss, high thermal stability, and conform to IC process technology.
