The rise of such products as automotive, industrial, telecom, and networking chips in recent years has resulted in continued advancements in packaging and testing technologies, and the market revenue of these technologies has seen a corresponding rise as well. Demand for advanced packaging has been relatively strong thanks to high demand for 5G smartphones, consumer electronics, and high-performance processors.

In particular, the mainstream development of advanced packaging and testing is currently concentrated on three major fields: HPC chip packaging（2.5D/3D）, FOPLP（fan out panel level packaging）, and SiP（system in package）. Some of the other factors driving forward the technological development of advanced packaging also include improvements in end product functions, advancements in transistor gate sizes, reduction in advanced packaging L/S, and migration of chip interconnect technology from micro-bumping to hybrid bond.

According to TrendForce’s investigations, the advanced packaging market last year reached a revenue of US$31.037 billion in 2020（which was a 13% increase YoY）and accounted for 45.8% of the total packaging market. At the moment, most packaging and testing companies have successively entered the advanced packaging market, with Flip Chip applications accounting for the majority of applications across smartphone AP, WiFi chips, entry-level processors, and high-end PMICs. Flip Chip applications make up more than 80% of the total advanced packaging revenue.

In spite of continued growth, advanced packaging will unlikely overtake traditional packaging in terms of market share within 5-10 years

In spite of the multitude of companies that are eager to enter the advanced packaging industry, not all of them possess the technological competence to progress in R&D, thus making acquisition the fastest path to advanced packaging success. With regards to technological competence, foundries and IDMs are the likeliest candidates to enter the industry, as they already possess ample experience in chip development.

At the moment, TSMC, Intel, and Samsung are the most well-equipped to do so, respectively. With regards to outsourced operations, Taiwanese companies such as ASE, SPIL, and PTI lead the industry in terms of packaging technologies, while U.S.-based Amkor is able to compete for neck-and-neck with ASE. Although these aforementioned companies are not specialists in chip fabrication, they have an extremely strong grasp of the downstream assembly ecosystem, hence their superiority in advanced packaging.

On the other hand, thanks to China’s Big Fund, the trinity of Chinese packaging and testing operators（JCET, TFME, and Hua Tian）were able to acquire major global players, including STATS ChipPac, AMD-SUZ, and Malaysia-based Unisem, respectively, during the 2014-2019 period.

Hence, not only have the Chinese trio been able to raise their market shares and rankings in the global packaging and testing market, but they have also been able to acquire certain competencies in advanced packaging technologies.

The current market would seem to suggest that advanced packaging has been gradually cannibalizing the market share of traditional packaging. However, as applications including home appliances and automotive electronics still require traditional packaging, TrendForce believes that only after 5-10 years will advanced packaging overtake traditional packaging in terms of market share.
