Global shipments of smartphones declined by 12% in 2022 to reach 1.2 billion units, the lowest since 2013. Apple Inc. (NASDAQ:AAPL) replaced Samsung by achieving the highest-ever global smartphone shipment in the last quarter of 2022, securing around 23% market share in Q4 2022, with the launch of Apple Inc. (NASDAQ:AAPL)'s iPhone 14.

The Challenges Faced by Smartphone Chip Manufacturing in Keeping up with Moore's Law

While smartphones may not match the processing power of PCs and servers, their chips have been at the forefront of the manufacturing industry. Initially, the chips were 10nm and 7nm (nanometers) in size, but with the advancement in technology, 5nm chips have been introduced, with Apple Inc. (NASDAQ:AAPL)'s latest iPhone iterations boasting the 4nm chip process. Now companies like TSMC are hoping to develop 2nm chips, which means you can expect smaller chips with better efficiency and higher transistor density.

When discussing nanometers and transistor density, Moore's Law, which states that the number of transistors placed on silicon doubles every year, plays a significant role. It predicts a consistent advancement in processing technology. However, when the manufacturing process for chips is evaluated through the lens of Moore’s Law, the slowing down of technological processes is likely to be on the verge in the coming years.

While the transistor density continues to improve, it may be challenging for chip manufacturers to move to 2nm or smaller in the coming years, as maintaining pace with Moore's Law is becoming increasingly difficult due to the shrinking of chip geometrics. It means that Moore's Law is under strain.

Manufacturers are still able to deliver significant improvements in chip manufacturing through innovations that radically change the transistor structure and constituent materials, despite chip densities not doubling every two years with the past consistency.

Prominent innovations include the replacement of the planar structure with the FinFET structure and the use of high k insulating films/metal gates to suppress gate leak current. Companies like Intel Corporation (NASDAQ:INTC), TSMC (Taiwan Semiconductor Manufacturing Co.), and Samsung have also invested in ASML to enable smaller chip circuits and larger wafers.

In the future, transistor structures are expected to evolve from FinFET to Gate-All-Around, where the channel’s region is surrounded by a gate that will help suppress the leak current and increase the gate’s current driving power. Silicon and strained silicon for the channel region are likely to be replaced with germanium and group III-V compounds, allowing for high-speed transistor operation.
