Apple might use a self-developed 5G modem chip for iPhones from next year

Apple 5G phone. Apple is apparently planning and designing to partner with Taiwan Semiconductor Manufacturing Co. for the production of its own 5G modems for future iPhones.

Apple 5G phone: Wall Street journals reports

In 2019, the company bought the most of Intel’s smartphone-modem business, including 2,200 workers;
In Qualcomm’s hometown, San Diego, Apple is promoting nearly around 140 positions directly associated with developing and accomodating cellular modem chips;
In 2021, Qualcomm’s CFO said the company anticipated supply of 20% of the 5G modems Apple uses in its mobile devices in 2023, while the company presently supplies nearly 100% of them now.

With these three points in mind, it appears like Apple is not only creating its exclusively 5G modems, but it will also be essential as it will give the company even more profit over opponents, as explained by Wayne Lam, senior director of research at CCS Insight.

Apple 5G phone: 5G modern chips

Apple is apparently negotiating with ASE Technology, which owns Advanced Semiconductor Engineering (ASE) and Siliconware Precision Industries (SPIL), to package some of its first customized 5G modem chips.

The report suggests that ASE and SPIL have both been Qualcomm’s partners for packaging 5G modem chips for iPhones, including its latest Snapdragon X65 5G modem-RF system now being fabricated at Samsung Electronics.
Apple has already structured its principal chip manufacturing partner TSMC to start producing most of its new in-house modem chips.

Apple 5G phone: TSMC 4-nanometer technology

Apple and TSMC are presently demonstrating the production of Apple’s in-house modem designs using TSMC’s 5-nanometer process, but they will switch to the more recent and advanced 4-nanometer technology for mass production.
TSMC is already targeting to use of 4-nanometer technology for the chief A-series chip in the 2022 ‌‌iPhone‌‌ lineup, with 2022 iPads and 2023 iPhones moving to 3-nanometer technology for their A-series chips.
