ISL6545CBZ-T_SN75LBC176DR Introduction

The details are shown in the figure below. . 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. 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.

TI has been steadily ramping up its production of analog chips on 300mm wafers in recent years to cut costs and increase productivity. TI said the 300mm fab yields 40% cheaper chips than the 200mm process used by competitors. Also, for analog use, the ROI of a 300mm fab is likely to be higher because it can last 20 to 30 years.

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

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

For SAW, also called Rayleighsurface wave, there are both longitudinal waves and transverse waves. . The particles in the solid vibrate in an elliptical trajectory, and the long axis of the ellipse is perpendicular to the surface of the solid.

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.
