Apple APL1064 PMIC for iPhone 16e C1 Modem with TSMC 65/55 nm Process Essentials

Analysis of the Apple APL1064 PMIC from the iPhone 16e includes optical, X-ray, SEM, and TEM imaging, revealing its advanced structural features.

The Apple APL1064 component is a power management IC (PMIC) device from the iPhone 16e smartphone C1 modem. The power-efficient C1 modem is Apple's first custom-made in-house modem for cellular phone applications, replacing a Qualcomm SDX71M counterpart used in the iPhone 16 Pro smartphone. The present report describes an investigation of the APL1064 component's optical and X-ray photographs, optical study of the die inside the APL1064 component, plan-view images of the device delayered to the gate level, cross-sectional SEM images of the device structure, detailed cross-sectional TEM images, and advanced SCM and sMIM analyses of the dopant structure of the device.
