ABA3100RS3_AD1888JCP-REEL Introduction

Because analog ICs are the bridge between the physical world and the digital world, analog chips are widely used in end markets such as industrial, automotive, consumer and communications industries. Basically, where there is electricity, there is a demand for analog chips.

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 has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. At just 100 microns in size, these tiny timers are smaller than the diameter of a human hair, but they operate at much higher frequencies than quartz crystals, enabling the integration of high-precision and ultra-low jitter clocks directly into packages that contain other circuitry, TI say. This enables TI to introduce the industry's first crystalless wireless MCU for the embedded market, the SimpleLink CC2652RB, with the clock contained in the same chip.

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 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. .

Flexible VIN broadens application range: The TPS62840 has a wide input voltage range of 1.8VIN-6.5VIN and accepts a variety of chemistries and configurations, such as two lithium-manganese dioxide (2s-LiMnO2) cells in series , single-cell lithium thionyl chloride (1xLiSOCL2) batteries, four- and two-cell alkaline batteries, and lithium polymer batteries (Li-Po).

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

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

?? Because only the edge part is in contact with the underlying substrate, this structure is relatively fragile when under pressure, and similar to the membrane type, the heat dissipation problem also needs attention. In the Airgap type, an auxiliary layer (sacrificial support layer) is deposited before the piezoelectric layer is formed, and finally the auxiliary layer is removed to form an air gap under the oscillating structure.

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.
